from improper operation.

2 Getting Started

_____________________________________________________________________________________________________________________________________

2-3

2.3 Safety Symbols

The signs and symbols on the multimeter, which provide guidelines for safety and
handling, are displayed and described below.

This symbol advises the user of a possible danger area.
Please consult the manual (see “Connection of Measurement
Leads” and Chapter “Operating Instructions”).

This symbol makes the user aware, that a dangerous
voltage can be present at measurement connectors.

The CE mark means, that the manufacturer has issued an
EC Declaration of Conformity for this multimeter. This declaration
certifies, that this multimeter conforms to the pertinent requirements
of EC directives.

2.4 Accident Prevention

While using this measurement unit, precautions to prevent an accident should be
taken, appropriate to the use of a measurement device.

It is especially important to observe , that during current measurement, a very low
impedance i.e. 0.1Ω exists between the Hi and Lo connectors, so that a cur­rent/voltage, which is applied to the Hi connector, can be contacted by a cable that is
connected to the Lo connector.

2.5 Connecting the Unit to Main Power

This PREMA measurement unit is designed to be connected to AC Main Voltage, at a
frequency of 50 Hz or 60 Hz. The rear panel of the unit is equipped with a standard
DIN grounded power connector.

!

Grounding

_____________________________________________________________________________________________________________________________________

2-4

Before connecting the unit to power, you should make sure that it is set to the right
voltage (indicator and fuse).

The voltage selection switch with integrated fuse is located right under the power
connector, where you can also read off the current voltage setting; a setting of
"220V" represents an AC voltage from 220V to 240V, "110V" represents a voltage
from 100V to 120V.

Switching the AC Voltage is done as follows:

)

1. Unplug the unit.

2. The clamp for the fuse is located between the plug and the power selector and
must be removed. For a setting of "110V" you will need a fuse rated at 0.4A;
for "220V" you’ll need a fuse rated at 0.2A.

3. Place the necessary fuse in the clamp and push the clamp back in.

4. Turn the cylinder with the voltage indicators once left or once right to the de­sired setting, so that the voltage that is currently set is indicated by the white
arrow on top.
The indicators are used as follows:

Setting Voltage Range

110 V 90 V

RMS

Table: Main Voltage Ranges

2.6 Grounding

In order to protect the user, the unit’s case is grounded through the grounding lead of
the power cable. To ensure proper grounding, the power cable should always be con­nected to a properly grounded power connector.
The unit case is galvanically separated from the measurement connectors and inter­face ports.

The back of the unit is equipped with a grounded screw, identified by the

sym-

bol, where the user can connect a separate ground line (rack mounting bracket).

2.7 Warranty

PREMA warrants the reliable function of the unit for a period of two years from the
date of delivery.
Repairs that need to be carried out during the warranty period are not billed to you.

Damage caused by inappropriate use of the unit, or by surpassing specified limits,
does not fall under PREMA’s warranty obligations.
Please be aware, also, that PREMA will not be held liable for damages, incidental or
coincidental, associated with the use of this measurement device.

2.8 Certificate

Each Digital Multimeter 5017 is provided with a calibration certificate at the factory,
certifying the location, date, and traceability of the unit’s calibration to the user.
Please look for this certificate at delivery time. It can also be useful as a control for
yearly recalibrations, since PREMA warrants that the unit will remain within specifi­cations for one year, and recommends recalibration after that time.

2.9 Turning it on

The multimeter can be switched on with the

STANDBY KEY

after connecting the power
cable. A device setting with measurement function, range and time can be stored as a
power-on setting in the "Configure Menu, Settings, Save Settings".
Switch off the instrument also with the

STANDBY KEY

.

The 5017 is then in standby mode. The red LED at the bottom left of the front panel
lights up.
The analog board of the unit is provided with power, even in standby mode, so that no
warm-up time needs to be taken into account when the unit is turned on.
Otherwise, warm-up times, as provided in Chapter “Technical Specifications”, should
be heeded.

Note: The transformer is not disconnected from Mains Power in standby

mode.

The instrument starts automatically with power-on after switching­off the unit by pulling the power cord.

Operation with rear panel inputs and Scanner

If the 5017 is to be operated from the rear panel inputs or the built-in scanner, please
proceed as follows:

)

1. Please remove all measurement cables from the connectors and
unplug the unit.

2. Turn the unit upside down, so that it is lying on its top shell.

3. Remove the four screws from the unit case's bottom shell.

4. Remove the unit case's bottom shell.

5. Tightly grasp and remove and then swap the two front-rear cable-set connec­tors that are visible on the left, as seen from the front panel of the unit. Only
the rear cable-set connector is connected to the preamplifier input circuitry.
The front cable-set connector is essentially a place-holder for the input that is
not being used.

6. While re-sealing the case, make sure that no wires are caught anywhere.

After turning the unit on (of course, you should first re-seal the unit’s cover) the
channel indicator field in the display will show the indication “REAR,” or a channel
number (if the Scanner is installed).
The software automatically checks for any rear-panel connections when the unit is
turned on and tests if the cable set connector has been moved from front panel input
to rear-panel input.

2.11 Rack Mounting

A rack adapter with two height units is offered for the 5017. The unit has a width of
one-half 19-inch, so it can be combined with another half-19-inch unit. More infor­mation about rack mounting can be found in the Chapter “Accessories.”

When installing the unit into a 19-inch rack, you should take into account, that the
ventilation openings in the back are not covered up. In addition, it should be possible
to cut power to the unit in an emergency, through the use of an EMERGENCY OFF
switch somewhere nearby.

Note: When the unit is installed in a 19-inch rack, and is to be operated through

the rear panel inputs or the Scanner, please make sure that the front-rear
cable-set connector in the unit has been connected to rear-panel input, prior
to installing the unit into the rack (see the previous section on
“Connection of Measurement Leads”).

2.12 Miscellaneous

Conforming to the Norm EN 61010

The Digital Multimeter 5017 is produced according to EN 61010. This means the
highest possible level of safety for the user, in relation to “dangerous body currents,”
“high temperatures,” and “mechanical endangerment".

This has the consequence, that this unit cannot be switched from front-panel to rear­panel input with a switch, as is found with multimeters of other brands.
The minimum of 5.5mm clearance and creepage distance at a nominal voltage of
1000Vdc is not implemented by standard slide switches. When 1000V are applied to
the front input connectors, and a switch to the rear input connectors is effected by
slider switch, a dangerous transfer of high voltage from the front inputs to the rear
inputs can occur.

In our opinion, the manual re-positioning of the Front-Rear cable-set connector is not
the most elegant, but certainly the safest solution at the moment. This does not mean,
however, that PREMA will not come up with a completely new solution in the future.

Scanner with Model 5017SC

For the model 5017SC with integrated scanner it is important to take the DC and AC
voltage limits of the Scanner into account, depending on which option is installed.
The input voltage at the rear panel is limited to 125 Vpk with the standard scanner
option.

The limit of 1000Vpk continues to be valid for the front input connectors only.

Current measurement and the 1000V range can only be selected while using the front
input connectors .

Filter

To increase disturbance suppression for better stability of the measurement readings,
the input signals can be passed through a digital filter which operates as moving
average filter for the last ten readings. After the first ten readings have come into the
filter loop, each new reading thereafter replaces the oldest one.

Two filters are available:

• Automatic average value filter (Auto Filter)

• Fast Automatic average value filter (Fast Auto Filter)

• Moving average filter (Avg. Filter)

The Menu "Configure"

_____________________________________________________________________________________________________________________________________

4-14

Automatic Filter (Auto Filter)

The automatic filter calculates the moving average over ten readings and
additionally the difference between the last two successive readings, comparing this
result with a difference value preset in the factory (depending on measuring range,
function and time). The filtering process is restarted when the difference exceeds the
value preset in the factory.
The filtering process also restarts when function, range or measuring time are
reselected.

Fast Automatic Filter (Fast Auto Filter)

similar to the automatic filter, but the first value after switching of channels or ranges
is more stable.

Moving Average Filter (Avg. Filter)

The moving average filter operates according to the same principle as above but
does not permit any signal-dependent restarting of the filter loop.
This filter is restarted when a function, range or measuring time is selected and after
pressing the

FILTER

KEY.
This kind of filtering achieves additional disturbance suppression by more than
20 dB.

_____________________________________________________________________________________________________________________________________

5-1

5 Remote Control

This chapter describes operation of the 5017 via the IEEE-488 and RS232 interface in
remotely controlled measuring systems.
This instrument supports both interface types: IEEE-488 and RS232

5.1 Configuration

Some manual configurations must be made to enable operation of the 5017 via one of
the two interfaces IEEE-488 or RS232.
All necessary settings are made in the menu "Device, Interface".

• Select interface (RS232, IEEE-488)

• Assign device address for IEEE-488

• Set handshake mode for RS232

• Set the command set (standard is ‘5017’)

Select Interface

Select the interface with which the instrument is to be controlled in the menu "Device,
Interface" (see chapter "Manual Operation").
The 5017 is equipped in the standard version with the two most common interfaces
used in measuring systems, namely IEEE-488 and RS232.

Configuring the RS232 Interface

Transmission via the RS232 interface takes place with 8N1 format, i.e. a data word
has 8 bits, no parity bit and one stop bit. The transmission speed is fixed at 9600 Bd.

Handshake Mode

The 5017 permits setting of various handshake modes so that this instrument can
communicate with numerous RS232 control programs. Many programing languages
and the Windows terminal program use XON/XOFF handshake. A special RS232
cable (zero modem cable, see chapter ‘Accessories’ No. 3017) is required for
RTS/CTS handshake, but very fast and reliable data transmission is possible then.

Configuration

_____________________________________________________________________________________________________________________________________

5-2

End Detection under RS232

The end of a transmitted or received message is designated with a line feed character
"LF" in RS232 data transmission.

Configuring the IEEE-488 Interface

The device address and the terminator character of the messages (ASCII strings) are
of importance for programing and data transmission in communication between the
control computer and the 5017. The IEEE address can be assigned by the user, but the
terminator is fixed and defined by the 488.2 standard.

Setting the IEEE-488, Device Address

The device address is set via the menu "Device, Interface, IEEE488" (see chapter
"Manual Operation") and can be saved in the power-up status.
The device address set in the factory is 7.

End Detection in the IEEE-488, Message Transmission

When operating with the IEEE488 interface, the standard string terminators are used
for reception and transmission of messages (ASCII strings), namely "LF+EOI". "LF"
stands for "Line Feed" and "EOI" designates an interface line which is set by
hardware control.

Define the Command Set

Different command sets can be selected. In this way the 5017 can replace the DMMs
6047/6048 and 6001/5001/4001 and work with the same software.
Please chapter ‘Compatibility’ for special remarks and restrictions of the
compatibility.

5 Remote Control

_____________________________________________________________________________________________________________________________________

5-3

5.2 General Information concerning Remote Control

All functions which can be manually controlled via the keyboard can also be remotely
controlled, except for the device address assignment which can only be set via the
keyboard.

As soon as the instrument has received the first command via the interface, the
keyboard is disabled for manual control of the instrument functions. Manual control
via the keyboard is thereafter possible again after pressing the

LOCAL-BUTTON

.
In remote control mode the designator “Rem" is lit in the right window of the main
display.

The instrument understands up to 30 characters in a command. All characters are
ASCII characters. Several commands can be combined in and executed from a single
string of characters sent as one message (e.g. "VDR5A1"), but some commands must
be sent at the end of a string, as ‘NVxxxxxxxxx’, ‘Cnx’, ‘Slx’, ‘D1...’ and the ‘?­commands’.

The specific commands for controlling data transmission via the interface are
contained in the manual for the utilized IEEE bus interface and some are specific to
the programing language used.

Any space characters (SPACE, ASCII code 20H) contained in the character string
sent by the computer are ignored.
The instrument can receive commands (operation as LISTENER) and it can also send
device messages concerning its status (operation as TALKER). In this status the
indication "ADR" appears on the very right in the display.

The time when the instrument transmits messages can be defined by the computer.
One possibility is for the computer to address the instrument as TALKER, and then
read-out the device message. The second possibility is to operate the instrument in
SRQ (service request) mode. It then requests service from the computer when a status
change has taken place. Switchover to SRQ mode can be made with a command. The
basic status of the instrument after power-up is without SRQ

5.3 Special Features for the RS232 Interface

The DMM 5017 is directly sending measurement values when opening the RS232
interface. If this is not wanted, the command ‘CN0’ can be send from the PC. Then
the instrument sends only a measurement value, if ‘RD?’ comes from the PC.

Capabilities of the IEEE-488 Bus Interface

_____________________________________________________________________________________________________________________________________

5-4

5.4 Capabilities of the IEEE-488 Bus Interface

The IEEE computer interface has the following capabilities defined by the IEEE-488
standard:

SH 1 Handshake source function
AH 1 Handshake sink function
T6 TALKER function
L3 LISTENER function
RL1 Remote control
DC1 Reset function
DT1 Initiate function
SR1 Service request function

General IEEE-488.1 Messages

The instrument understands the universal commands DCL, SPE and SPD. The
command DCL (device clear) brings the instrument into its basic state (V dc, 300V).
Of the addressed commands it understands GET, GTL, LLO and SDC.
The commands have the following effects:

DCL Device Clear Sets the instrument to the basic state
SDC Selected Device Clear Sets the instrument to the basic state
GTL Go To Local Terminates remote control status
LLO Local Lock Out The instrument cannot be switched to manual

control via the local button (keyboard lockout)

5.5 RS232 / IEEE-488.2 Common Commands

In addition to the 488.1 commands, the 5017 also understands common commands
according to the IEEE-488.2 standard that can be used with both interfaces RS232
and IEEE-488.

The common commands are transmitted to the 5017 as ASCII character string which
must always start with an asterisk "*".

The following commands are implemented in the 5017:

*CLS Clear Status Byte (command)
*ESE Standard Event Status Enable (command)
*ESE? Standard Event Status Enable (query)
*ESR? Standard Event Status Register (query)

Register.
The reply is a decimal value whose binary meaning is as stated above.

*ESR? Standard Event Status Register Query

The command "*ESR?" reads the current contents of the Standard Event Status
Register. The contents of this register are written directly by the instrument according
to a certain event. After read-out this register is reset to 0.

5 Remote Control

_____________________________________________________________________________________________________________________________________

5-7

*IDN? Identification Query

The command "*IDN?" queries the identification designation of the 5017. Read-out
produces a character string with the following format:

"PREMA GmbH,5017 DIGITAL MULTIMETER,0,<year>-<week>-<Number>"
with <year> = Year of software version

<week> = Week of software version
<Number> = No. of software version

For example:
"PREMA GmbH,5017 DIGITAL MULTIMETER,0,97-10-01"

*OPC Operation Completed Command

The command "*OPC" sets the Operation Completed bit (Bit 0) of the Standard
Event Status Register after all currently running command sequences have been
executed completely.

*OPC? Operation Completed Query

The command "*OPC?" makes the instrument write an ASCII 1 into the output buffer
if all currently running operations have been completed.

*RST Reset Command

The command "*RST" executes a reset of the 5017. The instrument thereby takes the
default setting (*RST). All still running internal operations are aborted, but no
registers are reset.

RS232 / IEEE-488.2 Common Commands

_____________________________________________________________________________________________________________________________________

5-8

*SRE Service Request Enable Command

The command "*SRE <Number>" sets the mask for the Service Request Enable
Register. The individual numbers here have the following meaning:

Decimal value Contents of the Service Request Enable Register

0 Resets the register.
1 (Bit 0), sets measurement value
2 (Bit 1), sets Error message like "Overflow", "Sensor?", "Div/0"
4 (Bit 2), sets Error Available (EAV)
16 (Bit 4), sets Message Available (MAV).

128 (Bit 7), sets button pressed

Bit 3 and 6 are not assigned.

*SRE? Service Request Enable Query

The command "*SRE?" reads the contents of the Service Request Enable Register.
The meaning of the contents of this register is as described above for the *SRE
command.

*STB? Read Status Byte Query

The command "*STB?" reads out the status byte of the 5017. The value of the Status
Byte is always 0, because the measurement value is set back after a new command.
Use SRQ if you want to check when a maeasurement value is available.

Decimal value Meaning in the status byte register

1 (Bit 0), Measurement Value available
2 (Bit 1), Error like "Overflow", "Sensor?", "Div/0" occured
4 (Bit 2), Error Queue.
16 (Bit 4), Message Queue.
32 (Bit 5), Event Summary Bit (ESB).
64 (Bit 6), Master Summary Status (MSS)/ Request Service (RQS)
128 (Bit 7), Button pressed

5 Remote Control

_____________________________________________________________________________________________________________________________________

5-9

Bit 3 is not assigned.
To determine exactly what events have taken place, query the corresponding status
registers.For example, if Bit 5 (ESB) is set, the cause can be determined with the
command"*ESR?".
For the IEEE488 interface, setting of Bit 6 activates the SRQ line so that the
controller card in the computer can respond.

*TST? Self Test Query

The command "*TST?" interrogates the result of the power-up self test of the
instrument. The reply is “0“ is the self test was completed without error. If any other
value is obtained, please contact PREMA GmbH.

*WAI Wait-to-Continue Command

The command "*WAI" prevents execution of further commands until the operations
of a previous command have been completed.

D0 switches display mode off again and the display according to the active operating
mode and function appears.

String Length Selection

_____________________________________________________________________________________________________________________________________

5-16

5.9 String Length Selection

The digital multimeter can send different length messages to the computer whereby
the desired message length is selected with L0 or L1. The latest measurement reading
is returned if the computer sends the command L0. The status information is not
output in response to L0. In response to L1 the instrument sends the most recent data
including the status information.

5.10 SRQ Mode

If the digital multimeter is not to be continually interrogated by the computer but
instead the digital multimeter is to request service from the computer when a status
change has taken place, SRQ mode (service request) must be switched on with the
command Q1.
A SRQ is sent, for example, when keyboard input has been made, when error
messages appear. Utilization of SRQ mode requires that the connected computer can
recognize a SRQ and reply to it with a serial poll (see computer manual).

5.11 Operation of the Digital Multimeter as TALKER

On request by the computer, the instrument sends a message containing its present
status and the most recent measurement reading. For this purpose the computer must
address the instrument as TALKER. The instructions how to do this are contained in
the manual of the computer manufacturer. The message ‘ADR’ is lit in the right
window of the display when the instrument has been addressed as TALKER.

The transmitted message consists of a character string and a fixed terminator at the
end of each character string enabling the computer to recognize the end of the
transmission. The message consists of two message units. The first unit contains the
data of the most recent measurement reading or calculation result, and the second unit
contains data concerning the programing status. The two message units are
transmitted as complete data record. The string terminator is fixed and defined with
IEEE-488.2 standard as "LF + EOI".
The ASCII (ISO 7 bit) code is used for the transmission.

The length of the second message unit is fixed and always consists of 27 characters
plus the terminator character. The length of the first message unit is 14 characters for
output of measurement readings and calculation results.

_____________________________________________________________________________________________________________________________________

5-17

Only the first message unit is transmitted when the short string is requested
(command “L0"). The status information (2nd message unit) is not sent in this case.

Description of the Message Record Sent

The following table gives an overview of the possible lengths of the message record
depending on the selected operating mode.
A message record consists of one (short string format) or of two (long string format)
message units, followed by a terminator character. The second message unit is called
the status information.

40 characters + terminator character

Example: +01.298764E+0MRVDP00A0R2F0T2D0S0Q0MOFB00"+ Terminator

or in short string format (13 characters)
+01.298764E+0" + Terminator

Example:

ERROR 01 MR04P00A1R6F0T2D0S0Q0MOFB00"+ Terminator
ERROR 01 + Terminator

The numbers in brackets (..) apply for the number of characters in short string format.

The measurement reading or a text message appears in the first message unit.
Text messages are ERROR x, NULL, CAL.
Character positions not required are filled with blanks.
The second message unit (status information) commences at the 14th character.

_____________________________________________________________________________________________________________________________________

6-1

6 Calibration

6.1 Calibration Periods

PREMA recommends that the unit be calibrated after one year has elapsed.
Within that year, specification data are guaranteed to be valid.

6.2 PREMA Calibration Service

You can have your unit calibrated by PREMA or by a local calibration lab. Call the
telephone number indicated on the front of the manual, in order to obtain information
about the price and duration of this service. We make every effort to return the unit to
your use as quickly as possible. In addition, when we perform a full calibration, you
receive a factory certificate.
Calibrations with an official certificate can also be obtained from PREMA.

6.3 Necessary Equipment

The following aids should be available to you, in order to be able to carry out a
complete calibration of the unit:

• Multifunction Calibrator for DC Voltage, DC Current, AC Voltage, AC

Current, and Resistance to at least 100M Ω, with a minimum resolution of 6½
digits (e.g. Datron 4800), or

• Voltage Standards (e.g. Fluke 732A, 10V) and Resistance Standards and

• Short-Circuit Terminators (three of them, e.g. PREMA 3016 Short-Circuit
Terminator Set) in order to perform the zero correction .

• Connection cables with gold-plated Banana Plugs (e.g. PREMA 3014 or 3015,
Precision Cable Set)

As an alternative you can also utilize less precise sources with good short-time
stability; the value of the source can be checked with PREMA’s 8½ digit DMM 6048.
You can then enter the DMM 6048’s reading into the 5017 as calibration value.

With this method, even 5½ digit calibrators can be used to calibrate 7½ digit
multimeters.

6.4 Automated Calibration

Automated Calibration

_____________________________________________________________________________________________________________________________________

6-2

The calibration of the 5017 can be automated with a computer and a Multifunction
Calibrator.
All measurement functions can be remotely controlled by the computer, through a
special command set (for more information see chapter “Remote Control”).

Calibration can normally be carried out entirely by remote control, without any need to
manually adjust potentiometers or capacitors.

For a complete calibration, the following measurement functions must be calibrated:

DC Voltage 300mV, 3V, 30V, 300V, 1000V
AC Voltage 200mV, 2V, 20V, 200V, 700V
DC Current 200µA, 2mA, 20mA, 200mA, 2A
AC Current 200µA, 2mA, 20mA, 200mA, 2A
2-wire Resistance 30kΩ, 300kΩ, 3MΩ, 30MΩ
4-wire Resistance 300Ω, 3k Ω, 30kΩ, 300kΩ, 3MΩ, 30MΩ

The measurement functions for frequency, period, temperature, and the lower 2-wire
resistance are automatically calibrated through the measurement functions listed above.

All ranges of individual measurement functions must be calibrated separately. In order
to properly set the zero-point, it is very important to carry out an offset correction
prior to calibration on each range of each measurement function.

Even after calibration, an Offset Correction should be carried out on a regular basis, at
least once a month.

6 Calibration

_____________________________________________________________________________________________________________________________________

6-3

6.5 Important Steps prior to Calibration

The following items must be taken care of before the calibration procedure is started:

1. The calibration environment should be at a stable temperature of at least

18°C (64.4°F), but no more than 28°C (82.4°F). Ideally, the temperature
should be 23 ±1°C (73.4°F). In order to prevent erroneous measurements
due to temperature fluctuations, you can wrap the connectors at the unit in a
heat-insulating cloth (like a dust cloth).

2. There must be a 2-hour warm-up period before the calibration is started.

3. Make certain, that the measurement connectors are set to front operation .

If the connectors are set to rear operation, switch them to front operation, as
described in the chapter “Getting Started.”

5. An offset correction must be carried out for every measurement range of

every measurement function.
If you are working with a multifunction calibrator, the offset correction is
carried out when the unit is already connected to the calibrator, and the
calibrator is set to “Zero” (the calibrator’s zero-point).
It is important, however, that the true unit zero-point be set after calibration,
by using the short-circuit terminators on the 5017 front input connectors.

6. Wherever possible, use shielded cables, as short as possible, and with gold-

plated connectors. In this manner, you can make certain that the
thermoelectric voltage at the measurement connectors is kept as small as
possible.

7. After connecting a cable, or after changing the measurement function or

range, you should wait at least one minute, before the first measurement
value is read.

PIN Number and Calibration Switch

_____________________________________________________________________________________________________________________________________

6-4

6.6 PIN Number and Calibration Switch

Calibration can be protected against accidental or incorrect calibrations, through the
use of a rear calibration switch and a special PIN number.

The calibration button is located on the rear panel, and can be pushed with a pointed
object (pen, pencil, paper clip, etc.). This button can be pushed after the calibration
menu has been selected. At the same time, a request to input the PIN number will
appear in the display.

6 Calibration

_____________________________________________________________________________________________________________________________________

By following the steps described above, each measurement function and measurement
range is calibrated.

The following measurement functions and ranges must be calibrated:

Measurement Function Measurement Ranges

Vdc 300mV, 3V, 30V, 300V, 1000V
Vac 200mV, 2V, 20V, 200V, 1000V

Ω4W 300Ω, 3kΩ, 30kΩ, 300kΩ, 3MΩ, 30MΩ
Ω2W 300kΩ, 3MΩ, 30MΩ

Table: Measurement Functions to be calibrated

Vac+dc, Iac+dc, Frequency, Period and Temperature Measurement are calibrated
through the measurement functions named above.
The lower resistance ranges are only calibrated in the 4-wire resistance measurement.

Changing the PIN Number

By default, the 7-digit PIN No. is set to 0000000. If you want to change this number
please proceed as follows.

Press Key Display / Action

1. cal key on the rear
panel

1 PIN:0 000000

Enter a PIN No. (default: 0000000), with correct PIN No. the display

shows aternate "CAL" and the reading.

2. cal key on the rear

An offset correction must be carried out for the following measurement functions and
ranges:

Measurement Function Measurement Ranges

Vdc 300mV, 3V, 30V, 300V, 1000V
Vac 200mV, 2V, 20V, 200V, 700V

Ω2W 300Ω, 3kΩ, 30kΩ, 300kΩ, 3MΩ, 30MΩ
Ω4W 300Ω, 3kΩ, 30kΩ, 300kΩ, 3MΩ, 30MΩ

Table: Offset Correction for Measurement Functions

In order to eliminate thermoelectric voltage and lead resistance, and to correct the
zero-point, an Offset Correction must be carried out for each measurement function.

A correction of the zero-point is possible, when the existing deviation is less than
approx. 0.2% of the range’s full-scale value for DC Voltage measurements, or approx.
5% for all other functions.
If the deviation is greater, the message “Offset too high” is displayed.

Offset values that are too large can be adjusted in the “Offset” Math Program.

Note: To achieve a correct zero-point alignment, a warm-up period of at least two

hours should be observed.

After switching functions and ranges, you should wait for a running period of
at least two measurements before carrying out an offset correction.

6 Calibration

_____________________________________________________________________________________________________________________________________

6-7

6.8 Calibrating DC Voltage

Offset Correction for DC Voltage

To carry out the Offset Correction for DC Voltage measurements, a short-circuit must
be applied to the V-Ω front input connectors (Accessory No. 3016).
After triggering a zero-point correction by pressing the zero key, an Offset
Measurement is carried out for the curren tly set measurement range.

Notice: If calibration is done with a calibrator, the calibrator's offset has to be

corrected for at the 5017 front input correction. T he cables must be
properly connected between calibrator and 5017 and the calibrator set to
Zero, prior to the Offset correction of the 5017. Now perform the 5017
offset correction by pressing the zero key on the front panel.

Important: After calibration is completed and the calibrator removed, another offset

correction must be performed , with a short-circuit, at the 5017 front input
connector as described above.

Calibration of DC Voltage

After selecting the desired measurement range, an exactly known positive or negative
reference voltage source is connected to the input connectors. The voltage can be
between 5% and 100% (preferably between 20% and 100%) of the display range for the
measurement range in question.
If the input voltage is not in this range, an error message is displayed.

The 5017 will now display a value that should correspond to the value of the known
voltage source. If the reference value deviates too much from the measured value, the
measurement range must be recalibrated.

If several measurement ranges are to be calibrated, the process described above is
started again for the next range.

Calibration of Resistance Ranges

_____________________________________________________________________________________________________________________________________

6-8

6.9 Calibration of Resistance Ranges

Offset Correction

When zeroing two-wire resistance measurement, the V Ω-Hi and VΩ-Lo connectors
should be short-circuited, by connecting a short-circuit terminator to these front input
connectors, instead of the resistance to be measured.

In four-wire resistance measurement, the real offset value is determined, by using two
short-circuit terminators (Accessory No. 3016) to short-circuit the V Ω-Hi and VΩ-Lo
connectors first, and then the two Sense connectors. The Sense and Source connectors
are then connected to each other with a third short-circuit terminator, to accomplish a
four-wire short.

It is important to make certain, that the “shortest” short-circuit is created at the Sense
connectors, to prevent contact resistance or pass-through resistance from being
measured.

Notice: If calibration is done with a calibrator, perform a calibration offset cor

rection as discribed above with DC voltage.

Important: After calibration is completed, the 5017 zero-point must be readjusted

again, with short-circuits, as described above.

Calibration of Resistance

Resistance ranges should be calibrated through four-wire resistance measurement. The
same calibration factors are then used for two-wire resistance measurements.
Only the higher resistance ranges need to be calibrated separately in 2-wire
measurement.

In addition , all of the two-wire resistance ranges can also be calibrated sep arately.

The zero offset correction must be performed with the ZERO key. In addition, chapter
7, ‘Operating Instructions’ should be considered, esp ecially referring to compensation
for measurement cable resistance.

Note: In 2-wire resistance measurement the V-Ω-Hi plug may not be

connected to the Sense-Hi plug.

6.10 Calibration of AC Voltage

An offset correction has to be proceeded for all ranges as described for the DC voltage.

Calibration of AC Voltage measurement is carried out without DC Voltage coupling.
The AC Voltage ranges should be calibrated with a Sine Voltage that has a frequency of
1kHz.
The same calibration factor is transferred for the AC Voltage function with DC
Component.

In all other ways, you can proceed as with DC Voltage calibration.

6.11 Calibration of DC and AC Current

An offset correction should be carried out with open connectors. During AC Current
calibration, only the function for AC Current without DC Component is calibrated.

The reference currents shall consist of DC current for the DC Current function, and of
a 1kHz Sine Current for the AC Current function.

Notice: In the 2A range, the calibration current must not exceed 1A.

6.12 Calibration of Temperature

1. Preparations

a) Warmup-period: The DMM 5017 to be calibrated should have run for at least 1h.

2. TEMP-Function: ZERO Offset Correction

a) Insert a four-wire shorting-bridge at the input of the DMM5017, i.e. shorten the four

DMM 5017 Volt/Ohm-inputs - Sense and Source - HI against LO and both pairs
against each other.

b) On the DMM5017 select 1sec integration time and press the TEMP-button. The

DMM5017 will then display ‘Sensor ?’, because ZERO Ohms as sensor input is not

specified. But performing this sequence of operations corrects for the OHM­function ZERO-offset, with the OHM-function implemented as fundamental function
for the Temperature-measurement with RTDs. That means here, the DMM5017
display ‘Sensor ?’ is not an error !

c) Press the following buttons in sequence to select the RTD-type (e.g. Pt 100):

Menu/↵ A 3 Device ↵ A 3 Temp Sensor ↵ A Pt 100 ↵ Menu/OUT.
Wait for some 10min for thermal stabilization.

d) On the DMM5017 with the TEMP-function selected perform the ZERO-offset

correction by pressing the following buttons in sequence:
2nd TIME/ZERO
The DMM5017-display will now show: ‘done’.

3. TEMP-Function: Calibration

a) Remove the four-wire shorting-bridge from the DMM5017 input terminals and

connect the RTD of the above selected RTD-type onto which the following
calibration has to be performed.

b) On the DMM5017 press again the TEMP-button: The actual temperature is now

displayed with the EN60751 factory calibration. Wait for another some 10min for
thermal stabilization.
On the DMM5017 activate the calibration mode by pressing the Cal-button on the
rear. The display will now ask for the input of the PIN number (Personal
Identification No.) that saves your data under this secret No.. Enter your PIN here or
simply press the Menu/↵-button without entering any PIN: The DMM5017-display
now starts flashing alternatingly ‘CAL.’ and the actual temperature display with the
EN60751 factory calibration.

c) Press the following buttons in sequence to recalibrate the DMM5017 TEMP-

function:
Menu/↵ A 2 CONFIGURE ↵ A 4 Calibration ↵ A 1 Enter Value ↵ <> now
input the new temperature calibration value here ↵
To ensure the successful recalibration the further flashing DMM5017-display now
shows ‘Cal.’ and the recently entered temperature calibration value.

d) Press the following buttons to permanently save the new temperature calibration

value:
Menu/↵ A 2 CONFIGURE ↵ A 4 Calibration ↵ A 2 Store Cal. ↵
The DMM5017 displays ‘wait...’ until the data recording into the EEPROM has
finished.
Then the DMM5017 starts flashing again still indicating that the calibration mode
has been activated.

e) Press the Cal-button on the rear of the DMM5017 to leave the calibration mode.The

DMM5017 now displays the recalibrated temperature calibration value.

4. TEMP-Function: Extended list of RTDs

Press the following buttons in sequence to select the recently calibrated RTD, e.g.
Pt100 :

Menu/↵ A 3 DEVICE ↵ A 3 Temp. Sensor ↵ A 6 Cal. Pt100 ↵ Menu/OUT.

Cal. Pt100 is new in this list as the USER calibrated version of a Pt100-Sensor. The

DIN-EN 60751 calibrated version is still available in the menu as
A 3 Pt100 but without the addendum Cal.

6.13 Storing Calibration Values

Storage of calibration values is absolutely necessary to store them durably. Every
calibration step is stored only temporarily, so that the files are deleted if you switch of
the instrument.

If you wish to interrupt a calibration procedure and turn off the unit, you can do so, only
if you store the calibration with the menu "Store Cal." before you switch off power.
Y ou could then continue the procedure the next day for example, from the point where
you left off.

7.1 DC Voltage Measurement

Input Resistance in DC Voltage

To make use of the high linearity of the measurement process, the input resistance for
voltage measurements up to 3V is set very high (>10GΩ). In this range, the unit al­lows precise measurements, with a maximum load error of 1ppm, even at measure­ment objects with an internal resistance of 1kΩ.

In the 30V, 300V, and 1,000V ranges, for example, and with a 100Ω internal resis­tance in a measurement object with a resolution of 100,000, a corresponding error of
one digit step occurs.

The values of the input resistance in the individual measurement ranges, and the
maximum display ranges, are shown in the following table:

Full Input Maximum
Range Scale Resistance Resolution

300 mV 30 100 000 10 GΩ 10 nV

The error, in %, of a measurement, is calculated as follows:

Error = 0.0001% (1 ppm)

The error rating, in ppm (parts per million), often used in measurement technology, is
derived from: Error(%) x 10,000.

Series Mode Suppression

One of the main advantages of the integrating measurement process lies in the high
suppression of series AC voltage components (e.g. main line scatter), which are
overlaid on the actual signal voltage. For frequencies, where the measurement time is
an integer multiple of the period length, an infinitely high noise suppression level
theoretically results.
Short-term fluctuations of the mains frequency would lead to measurement errors in
case of fixed measurement times.

That is why, in the 5017 a PLL circuit (Phase Locked Loop) is used to synchronize
the measurement time with the period of the main line frequency. An integer multiple
of the mains period is always contained in the measurement time.
Due to the fully integrating measurement process, the positive and negative half­waves of line voltage are neutralized. Line scatter can thereby be completely sup­pressed.
The 5017 achieves a Series Mode Suppression of >100 dB with line frequencies of
50 / 60Hz ± 5%.

Common Mode Suppression

The ability of a measurement device, to display only the desired differential signal
between the “HI” and “LO” inputs, while suppressing an equal voltage on both
clamps against ground, is designated as Common Mode Suppression. In an ideal
system, no errors would be generated, but in real life, scatter capacitances, isolation
resistances, and non-symmetrical resistances convert a part of the common mode
voltage into a series voltage.
Common mode suppression in the 5017 is more than 160dB, with a non-symmetry of
1kOhm in the leads.

Thermal Voltages

One of the most common error sources in DC Voltage measurement in the low signal
range is the thermal voltage produced by thermal EMF.
These thermal voltages occur at the contact points of different metals that are at the
same or different temperature levels.

Diagram: Thermal Voltage sources in a measurement circuit

DC Voltage Measurement

_____________________________________________________________________________________________________________________________________

7-4

The sketch shows the possible thermal voltage sources in a measurement circuit,
which can exist at an external connection point (Contact 1/2), but can also occur in
the connectors of the measurement unit.
It is always important to carry out all connections with the same material, or at least to
use materials, that produce very small thermal voltages, when they are put in contact
with each other.

The table below shows the different thermal voltages for diverse material
combinations:

Contact Materials approx. Thermal Voltage

Cu - Cu < 0,3µ/°C
Cu - Ag (Silver) 0,4µ/°C
Cu - Au (Gold) 0,4µ/°C
Cu - Sn (Tin) 2-4µ/°C (dep. on composition)

For example, if material 1 consists of a silver lead and material 2 consists of a copper
cable, a connection between contacts 1 and 2 at a temperature difference of just 1°C
already results in a thermoelectric voltage of 400nV. In the smallest voltage range,
with a resolution of 7½ digits (10nV sensitivity), this would result in an error of ± 40
digits.

Noise Effects Through Inductive Interferences

If the measurement leads are located near changing magnetic fields, generated for
example by a nearby high-voltage line, induction will cause an interfering voltage in
series with the measurement voltage.
By using twisted pair measurement leads, inductive interferences by a magnetic field
can be very strongly reduced. One should also take care not to allow the leads to hang
around loosely and move around during measurements, since that can cause error
voltages.
An additional measure for the reduction of noise is to increase the distance to the
magnetic field, or if possible to shield measurements from it.
