Safety Precautions
1 Safety Features and Precautions
Y ou have selected an instrument which provides you with a hig h level
of safety.
This instrument fulfills the requirements of applicable European and
national EC directives. This is confirmed by means of the CE mark. A
corresponding declaration of conformity can be requested from Dranetz-BMI.
The TRMS digital multimeter has been manufactured and tested in accordance with the following safety regulations:
IEC 61010–1:2001 / DIN EN 61010–1/VDE 0411–1:2002.
When used for its intended purpose (see page 10), safety of the operator, as well as that of the instrument, is assured. Their safety is however not guaranteed, if the instrument is used improperly or handled
carelessly.
In order to maintain flawless technical safety conditions, and to
assure safe use, it is imperative that you read the operating instructions thoroughly and carefully before placing your instrument into service, and that you follow all instructions contained
therein.
The multimeter is equipped with an automatic socket blocking mechanism for your safety, and in order to safeguard your instrument. This
mechanism is linked to the rotary switch and only allows access to
those jacks which are actually required for the selected function. It
also prevents the user from turning the rotary switch to impe rmi ssi ble
functions after the measurement cables have already been plugged in.
Measuring Categories and their Significance per IEC 61010-1
The measuring category and the maximum rated voltage which are
printed on the device apply to your measuring instrument, for example
1000 V CAT III.
Observe the following safety precautions:
• The multimeter may not be used in potentially explosive atmospheres.
• The multimeter may only be operated by persons who are capable
of recognizing contact hazards and taking the appropriate safety
precautions. Contact hazards according to standard exist anywhere,
where voltages of greater than 33 V RMS or 70 V DC may occur.
Avoid working alone when taking measurements which involve
contact hazards. Be certain that a second person is present.
• Maximum allowable voltage between the voltage measuring terminals, and between all connections and earth is 1000 V for measuring category III, or 600 V for measuring category IV.
CAT Definition

Safety Precautions
• Be prepared for the occurrence of unexpected voltages at devices
under test (e.g. defective devices). For example, capacitors may be
dangerously charged.
• Make certain that the measurement cables are in flawles s condition
e.g. no damage to insulation, no interruptions in cables or plugs etc.
• No measurements may be made with this instrument in electrical
circuits with corona discharge (high-voltage).
• Special care is required when measurements are made in HF electrical circuits. Dangerous pulsating voltages may be present.
• Measurements under moist ambient conditions are not permitted.
• Be absolutely certain that the measuring ranges are not overloaded
beyond their allowable capacities. Limit values are included in
chapter 8, “Technical Data”, in the table entitled “Measuring Functions and Measuring Ranges” in the “Overload Capacity” column.
• The multimeter may only be operated with installed batteries
or rechargeable batteries. Dangerous currents and voltages are
otherwise not indicated, and the instrument may be damaged.
• The instrument may not be operated if the fuse cover or the battery
compartment lid has been removed, or if its housing is open.
• The input for the current measuring range is equipped with a fuse
link.
Maximum permissible voltage for the measuring circuit (= rated
voltage of the fuse) is 1000 V AC/DC.
Use specified fuses only (see page 57)! The fuse must have a
breaking capacity of at least 30 kA.
Repair and Parts Replacement
When the instrument is opened, voltage conducting parts may be exposed. The instrument must be disconnected from the measuring circuit before the performance of repairs or the replacement of parts. If
repair of a live open instrument is required, it may only be carried out
by trained personnel who are familiar with the dangers involved.
Defects and Extraordinary Strains
If it may be assumed that the instrument can no longer be operated
safely, it must be removed from service and secured against unintentional use.
Safe operation can no longer be relied upon:
• If the device demonstrates visible damage
• If the instrument no longer functions, or if malfunctioning occurs
• After long periods of storage under unfavorable conditions, e.g.

Control Functions
4 Control Functions
4.1 Selecting Measuring Functions and Measur ing Ranges
The rotary switch is linked to the automatic socket blocking mechanism, which only allows access to two connector jacks for each function. Be certain to remove the appropriate plug from its respective jack
before switching to and from the “A” functions. The socket blocking
mechanism prevents the user from inadvertently turning the selector
switch to impermissible functions after the measurement cables have
been plugged in to the instrument.
4.1.1 Automatic Range Selection
The multimeter is equipped with auto-ranging for all measuring functions, except for temperature measurement, diode and continuity testing, and the MHz measuring function. Auto-ranging is active as soon
as the instrument is switched on. The instrument automatically selects
the measuring range which allows for highest possible resolution of
the applied quantity. When the instrument is switched to frequency
measurement, the previously selected voltage measuring range remains active.
The Auto-Ranging Function
The multimeter is switched automatically to the next higher range at
±(1 1999 d + 1 d → 0 1200 d), and to the next l o wer range at ±( 0 1 100 d -
1 d → 10990 d).
Exception, capacitance measurement:
The multimeter is switched automatically to the next higher range at
±(1 19 9 d + 1 d → 0 120 d), and to the next lower range at ± (0 1 10 d - 1 d

4.1.3 Quick Measurements
Measurements performed using a suitable fixed measuring range are
executed more quickly than those which utilize automatic range selection. Quick measurement is made possible with the following two
functions:
• Manual measuring range selection, i.e. selection of the measur-
ing range with the best resolution (see chapter 4.1.2).
or
•With the DATA function (see chapter 4.4). In this way, the appro-
priate measuring range is selected automatically after the first
measurement and the second measurement is executed more
quickly.
The selected measuring range remains active for the subsequent series
of measurements with these two functions.
4.2 Zero Offset / Relative Measurements
Depending upon deviation from the zero point, zero balancing or a
reference value for relative measurements can be stored to memory:
The applicable reference or correction value is deducted individually
for the respective measuring function as an offset from all subsequent
measurements, and remains in memory until deleted, or until the multimeter is switched off.
Zero balancing and reference value adjustment can be used for autoranging, as well as for manual measuring range selection.
Zero Balancing
∞ Plug the measurement cables into the instrument and connect the
free ends to each other, except for capacitance measurement in
which case the ends of the cables are not connected to each other.
∞ Briefly press the ZERO | ESC key.
The instrument acknowledges zero balancing with an acoustic signal, and the “ZERO ΔREL” symbol appears at the LCD. The value
measured at the moment the key is pressed serves as a reference
value.
∞ Zero balancing can be cleared by once again pressing the ZERO |
ESC key.
Note!
As a result of TRMS measurement, the multimeter displays a
residual value of 1 to 30 digits with short-circuited measurement
cables as the zero point for V AC / I AC or V(AC+DC) / I
(AC+DC) measurements (non-linearity of the TRMS converter). This has no influence on specified accuracy above 2% of
the measuring range (or 3% in the mV range).
Setting the Reference Value
∞ Plug the measuring cables into the instrument and measure a refer-
ence value (max. 5000 digits).
∞ Briefly press the ZERO | ESC key.
The instrument acknowledges storage of the reference value with
an acoustic signal, and the “ZERO ΔREL” or the “ΔREL” symbol
appears at the LCD. The value measured at the moment the key is
pressed serves as a reference value.

Notes Regarding Relative Measurement
• Relative measurement effects the digital display only. The analog
display continues to read out the original measured value.
• In the case of relative measurement, Ω / F or AC quantities may
also appear as negative values.
4.3 Display (LCD)
4.3.1 Digital Display
Measured Value, Unit of Measure, Type of Current, Polarity
The measured value with decimal and plus or minus sign appears at
the digital display. The selected unit of measure and type of current
are displayed as well. A minus sign appears to the left of the value
during measurement of zero-frequency quantities, if the plus pole of
the measured quantity is applied to the “⊥” input.
The “0.diSP ” parameter can be used to determine whether leading
zeros will appear or be suppressed at the measured value display (see
chapter 6.4).
Overranging
If the upper range limit of 12,000 digits is exceeded “0L” (overload)
appears at the display.
Exceptions: “0L” appears as of 1200 digits for capacitance
measurement, and as of 5100 digits for diode testing.
4.3.2 Analog Display
Measured Value, Polarity
The analog display demonstrates the dynamic performance of a moving-coil mechanism. This display is especially advantageous for observing measured value fluctuation, and for balancing procedures.
Two different display modes can be selected in the “SEt ” menu with
the help of the “A.diSP ” parameter (see chapter 6.4):
• Bar graph
• Pointer: The current measured value is tracked in real-time.
The analog scale displays a negative range of 2 scale divisions for the
measurement of zero-frequency quantities, allowing for precise observation of measured value fluctuation around zero. If the measured
value exceeds the negative range of 2 scale divisions, polarity is reversed at the analog display.
Scaling of the analog scale is automatic. This is very helpful for manual measuring range selection.
Overranging
Overranging in the positive range is displayed by means of the right
triangle symbol.
Refresh Rate
In the bar graph and pointer modes, the analog display is refreshed 40
times per second.

4.4 Measured Value Storage: DATA (auto-hold / compare)
An individual measured value can be automatically “frozen” with the
DA TA function (auto-hold). This is useful, for example, when contacting the measuring points with the test probes requires your full attention. After the measuring signal has been applied and the measured
value has settled in accordance with the “condition” listed in the table
below, the measured value is frozen at the digital display and an
acoustic signal is generated. The test probes can now be removed from
the measuring points, and the measured value can be read from the
digital display. If the measuring signal falls below the value specified
in the table, the function is reactivated for storage of the next value.
Measured Value Comparison (DATA Compare)
If the currently frozen value deviates from the first saved value by less
than 100 digits, the acoustic signal is generated twice. If deviation is
greater than 100 digits, only a brief acoustic signal is generated.
Note!
The DA T A function has no ef fect on the analog display , at which
the current measured value continues to appear. However , when
the digital display is “frozen”, the decimal point is fixed as well
(fixed measuring range, symbol: MAN).
The selected measuring range should not be manually changed
as long as the DATA function is active.
The DATA function is deactivated by pressing and holding the DATA/
MIN/MAX key (for approx. 1 second), when the measuring function
is changed or when the instrument is switched off and back on again.
1)
Reactivation results from falling short of specified measured value limits.
2)
Two acoustic signals are generated the first time a measured value is saved as a reference
value. For subsequent data hold, two acoustic signals are only generated if the currently
frozen value deviates from the first saved value by less than 100 digits.

Example
The voltage measuring range is set manually to 10 V. The first measured value is 5 V, which is stored to memory because it is greater than
10% of the measuring range (= 1 V), and is thus reliably above the
background noise level. As soon as the measured values drops to less
than 10% of the measuring range, i.e. amounts to less than 1 V which
corresponds to removal of the test probes from the measuring point,
the instrument is ready to store a new value.
4.4.1 Saving Minimum and Maximum Values – MIN/MAX Func-
tion
Minimum and maximum measured values applied to the measuring
instrument’s input after the Min/Max function has been activated can
be “frozen” at the display. The most important use of this function is
the determination of minimum and maximum values during long-term
measured value observation.
The Min/Max function can be activated in all measuring functions.
The Min/Max function has no effect on the analog display, at which
the momentary measured value continues to appear.
Apply the measured quantity to the instrument and set the measuring
range with the MAN / AUTO key before activating the Min/Max
function.
The Min/Max function is deactivated by pressing and holding the
DATA/MIN/MAX key (for approx. 1 second), when the measuring
function is changed or when the instrument is switched off and back
on again.
Note!
As opposed to the DATA function, the Min/Max function can
also be used for temperature measurement.

an adjustable sampling rate for long periods of time in the form of
measurement series. Data are stored to a battery backed memory module, and are retained even after the multimeter is switched off. The
system acquires measured values relative to real-time.
Stored measured values can subsequently be read out with the help of
DranWin 10 software. The only prerequisite is a PC which is connected by means of an interface cable to the USB⏐X-
TRA
bi-directional interface adapter, which is in turn plugged onto the DranTech

5.1 Voltage Measurement
Notes Regarding V oltag e Measurement
• The multimeter may only be operated with installed batteries
or rechargeable batteries. Dangerous voltages are otherwise
not indicated, and the instrument may be damaged.
• The multimeter may only be operated by persons who are capable
of recognizing contact hazards and taking the appropriate safety
precautions. Contact hazards exist anywhere, where voltages of
greater than 33 V RMS may occur.
The test probes may only be only gripped up to the finger guard.
Do not touch the metallic test probes under any circumstances.
• Avoid working alone when taking measurements which involve
contact hazards. Be certain that a second person is present.
• Maximum permissible voltage between the connector sockets, (9
and 10) and ground (8) is 1000 V for measuring category III, and
600 V for measuring category IV.
• Be prepared for the occurrence of unexpected voltages at devices
under test (e.g. defective devices). For example, capacitors may be
dangerously charged.
• No measurements may be made with this instrument in electrical
circuits with corona discharge (high-voltage).
• Special care is required when measurements are made in HF electrical circuits. Dangerous pulsating voltages may be present.
• Be aware of the fact that dangerous voltage spikes are not displayed during measurement with the low-pass filter. We recommend measuring voltage without the low-pass filter first, in
order to be able to detect any dangerous voltages.
• Be absolutely certain that the measuring ranges are not overloaded
beyond their allowable capacities. Limit values are included in
chapter 8, “Te chni ca l D ata”, in the table entitled “Measuring Functions and Measuring Ranges” in the “Overload Capacity” column.
Scope of Functions, Volta ge Measurement
1)
A 1 kHz low-pass filter can be used in this case, in order to filter out high frequency pulses of greater than 1 kHz, for example when performing measurements at pulsed motor drives.
2)

5.1.4 Transient Overvoltages
The multimeters are protected against transient overvoltages of up to 8
kV with wave-front durations of 1.2 ms and halftimes of 50 μs in the
voltage measuring range. If longer pulse durations are expected, for
example when conducting measurements at transformers or motors,
we recommend the use of our KS30 measuring adapter. It provides
protection against transient overvoltages of up to 6 kV with wavefront durations of 10, and halftimes of 1000 μs.
Continuous load capacity is 1200 V

5.7 Current Measurement
Notes Regarding Current Measurement
• The multimeter may only be operated with installed batteries
or rechargeable batteries. Dangerous currents are otherwise
not indicated, and the instrument may be damaged.
• Set up the measuring circuit in a mechanically secure fashion, and
secure it against inadvertent breaks. Select conductor cross-sections and lay out connections such that they do not overheat.
• An intermittent acoustic signal warns of current greater than 10 A.
An continuous acoustic signal warns of current greater than 16 A.
• The input for the current measuring range is equipped with a fuse
link. Maximum permissible voltage for the measuring circuit (=
rated voltage of the fuse) is 1000 V AC/DC.
Use specified fuses only! The fuse must have a breaking
capacity of at least 30 kA.
• If the fuse for the active current measuring range blows, “FUSE ”
appears at the digital display, and an acoustic si gnal is generated at
the same time.
• If a fuse should blow, eliminate the cause of overload before placing the instrument back into service!
• Fuse replacement is described in chapter 9.3.
• Be absolutely certain that the measuring ranges are not overloaded
beyond their allowable capacities. Limit values are included in
chapter 8, “Technical Data”, in the table entitled “Measuring Functions and Measuring Ranges” in the “Overload Capacity” column.

Interface Operation
7 Interface Operation
DranTech X
TRA
is equipped with an infrared interface for the transmission of measurement data to a PC. Measured data are optically
transferred through the instrument housing by means of infrared light
to an interface adapter (accessory), which is attached to the multimeter. The adapter’s USB interface allows for the establishment of a connection to the PC via an interface cable. Beyond this, commands and
parameters can be transmitted from the PC to the multimeter as well.
The following functions can be executed:
• Configuration and read-out of measuring parameters
• Measuring function and measuring range selection
• Start measurements
• Read out stored measured values
7.1 Activating the Interface
The interface is automatically activated for receiving operation (multimeter receives data from the PC) as soon as the interface is addressed
by the PC, assuming that the “irStb ” parameter has been set to “ir on ”
(see chapter 7.2), or the instrument is already switched on (the first
command wakes up the multimeter, but does not yet execute any further commands).
The “continuous transmission” operating mode is selected manually
as described below. In this operating mode, the instrument continuously transmits measurement data to the PC via the interface adapter,
which can then be displayed with the help of a terminal program.
Starting Continuous T ransmission Operation with Menu Functions
1nFo Z ... Z SEnd StArt send
The symbol blinks at the display in order to indicate interface operation.

Automatic Activation and Deactivation of Transmission Mode
Operation
If the sampling rate is 10 seconds or longer, the display is switched off
automatically between samples in order to prolong battery service life.
The only exception is when the multimeter is set to continuous operation. As soon as an event occurs, the display is automatically switched
back on.

Disconnect the instrument from the measuring circuit before
opening the battery compartment lid or fuse cover in order to replace batteries or fuses!
9.1 Displays – Error Messages
9.2 Batteries
Note!
Removing the Batteries During Periods of Non-Use
The integrated quartz movement draws power from the batteries
even when the instrument is switched off. It is advisable to
remove the batteries during long periods of non-use for this reason (e.g. vacation). This prevents excessive depletion of the battery, which may result in damage under unfavorable cond itions.
Note!
Battery Replacement
Stored measurement data is lost when the batteri es are replaced.
In order to prevent data loss, it is advisable to backup your data
to a PC with the help of DranWin 10 software before replacing
the batteries. The selected operating parameters remain in m emory, although date and time must be reentered.
Battery
The current battery charge level can be queried in the “1nfo” menu:
1nFo bAtt
:
2.75 V.
Make sure that no battery leakage has occurred before initial start-up,
as well as after long periods of storage. Continue to inspect the batteries for leakage at short, regular intervals.
If battery leakage has occurred, carefully and completely clean the
electrolyte from the instrument with a damp cloth, and replace the batteries before using the instrument.
If the “ ” symbol appears at the display, the batteries should be replaced as soon as possible. You can continu e wo rking with the instrument, but reduced measuring accuracy may result.
The instrument requires two 1.5 V batteries in accordance with
IEC R 6 or IEC LR 6, or two equivalent rechargeable NiCd batteries.

Replacing the Batteries
Attention!
!
Disconnect the instrument from the measuring circuit before
opening the battery compartment lid in order to replace the batteries.
∞ Set the instrument face down onto the working surface.
∞ Turn the slotted screw on the lid with the battery symbols counter-
clockwise.
∞ Lift off the lid and remove the batteries from the battery compart-
ment.
∞ Insert two new 1.5 V mignon batteries into the battery compart-
ment, making sure that the plus and minus poles match up with the
provided polarity symbols.
∞ When replacing the battery compartment lid, insert the side with
the guide hooks first. Tighten the screw by turning it clockwise.
∞ Please dispose of depleted batteries in accordance with environ-
mental protection regulations!
9.3 Fuse
Testing the Fuse
The fuse is tested automatically:
• When the instrument is switched on with the rotary switch in the A
position
• When the instrument is already on and the rotary switch is turned
to the A position
• In the active current measuring range when voltage is applied
If the fuse is blown or has not been inserted, “FuSE” appears at the
digital display. The fuse interrupts the current measuring ranges. All
other measuring ranges remain functional.
Replacing the Fuse
If a fuse should blow, eliminate the cause of overload before
placing the instrument back into service!
Attention!
!
Disconnect the instrument from the measuring circuit before
opening the fuse cover in order to replace the fuse!
∞ Set the instrument face down onto the working surface.
∞ Turn the slotted screw on the cover with the fuse symbol counter-
clockwise.
∞ Lift off the cover and pry the fuse out using the flat side of the fuse
cover.
∞ Insert a new fuse. Make sure that the fuse is centered, i.e. between
the tabs at the sides.
∞ When replacing the fuse cover, insert the side with the guide hooks
first. Tighten the screw by turning it clockwise.
∞ Dispose of the blown fuse with the trash.

Maintenance – Calibration
Attention!
!
Use specified fuses only!
If fuses with other blowing characteristics, other current ratings
or other breaking capacities are used, the operator is placed in
danger, and protective diodes, resistors and other components
may be damaged.
The use of repaired fuses or short-circuiting the fuse holder is
prohibited.
Note!
Testing the Fuse with the Instrument Switched On
After inserting the fuse with the instrument switched on, the
instrument must be switched off briefly and then switched back
on, or briefly switched to a non-current measuring range and
then back to the “A” measuring range.
If contact is poor or the fuse is blown, FUSE appears at the display.
9.4 Housing Maintenance
No special maintenance is required for the housing. Keep outside surfaces clean. Use a slightly dampened cloth for cleaning. Avoid the use
of cleansers, abrasives or solvents.
9.5 Return and Environmentally Sound Disposal
