1.1 Introduction

Fluke’s Hart Metrology Wells (9170, 9171, 9172, and 9173) are designed to be stable
heat sources that can be used in a laboratory or eld environment. With a calibrated
display and an optional built-in reference thermometer input (designated with “-R”),
Metrology Wells may also be used as a reference standard.

Metrology Wells feature interchangeable probe sleeves that t various sized diameter
probes.

The Metrology Wells’ controller uses a PRT sensor and thermoelectric modules or
heaters to achieve stable, uniform temperatures throughout the block.

The LCD display continuously shows many useful operating parameters including the
block temperature, block stability, heating and cooling status, and current set-point.
The temperature may be easily set with the control buttons to any desired temperature
within the calibrator’s specied range.

Metrology Wells are designed for laboratory performance that can be used anywhere.
With proper use, the instrument will provide continued accurate calibration of temper­ature sensors and devices. Before use, the user should be familiar with the warnings,
cautions, and operating procedures of the calibrator as described in the Getting Started
Guide.

3

Before You Start

Safety Information

or has been in a wet environment, take necessary measures to remove moisture prior
to applying power such as storage in a low humidity temperature chamber operating at
50°C for 4 hours or more.

DO NOT use this instrument for any application other than calibration work. The
instrument was designed for temperature calibration. Any other use of the instrument
may cause unknown hazards to the user.

Completely unattended operation is not recommended.

DO NOT place the instrument under a cabinet or other structure. Overhead clearance
is required. Always leave enough clearance to allow for safe and easy insertion and
removal of probes.

Use of this instrument at HIGH TEMPERATURES for extended periods of time
requires caution.

Completely unattended high temperature operation is not recommended due to safety
hazards that can arise.

If the instrument is used in a manner not in accordance with the equipment design, the
operation of the Metrology Well may be impaired or safety hazards may arise.

This instrument is intended for indoor use only.

BURN HAZARD

Each Metrology Well is equipped with a Block Temperature Indicator (front panel
LED HOT indicator – U.S. Patent 7,561,058) even when the instrument is unplugged.
When the indicator is ashing, the instrument is not powered and the temperature of
the block is above 50°C. When the indicator is illuminated, always on, the instrument
is powered and the block temperature is above 50°C.

DO NOT turn the instrument upside down with the inserts in place; the inserts will
fall out.

DO NOT operate instrument in any orientation other than vertical (block opening face
up). Risk of re or burn hazard may result due to excessive heat build up.

DO NOT operate on a ammable surface or near ammable materials.

DO NOT touch the well access surface of the instrument.

The block vent may be very hot due to the fan blowing across the heater block of the
Metrology Well.

The calibration well temperature of the Metrology Well is the same as the actual dis­play temperature, for example, if the instrument is set to 700°C and the display reads
700°C, the well is at 700°C.

The air over the well can reach temperatures greater that 200°C for high temperature
(400°C and higher) Metrology Wells.

Probes and inserts may be hot and should only be inserted and removed from the
instrument when the instrument is operating at temperatures below 50°C.

917X Series Metrology Wells

Safety Information

DO NOT turn off the instrument at temperatures higher than 100°C. This could create
a hazardous situation. Select a set-point less than 100°C and allow the instrument to
cool before turning it off.

The high temperatures present in Metrology Wells designed for operation at 300°C
and higher may result in res and severe burns if safety precautions are not observed.

ELECTRICAL HAZARD

These guidelines must be followed to ensure that the safety mechanisms in this instru­ment will operate properly. This instrument must be plugged into a 115 VAC (230
VAC optional), AC only electric outlet. The power cord of the instrument is equipped
with a three-pronged grounding plug for your protection against electrical shock haz­ards. It must be plugged directly into a properly grounded three-prong receptacle. The
receptacle must be installed in accordance with local codes and ordinances. Consult a
qualied electrician. DO NOT use an extension cord or adapter plug.

If supplied with user accessible fuses, always replace the fuse with one of the same
rating, voltage, and type.

Always replace the power cord with an approved cord of the correct rating and type.

HIGH VOLTAGE is used in the operation of this equipment. SEVERE INJURY or
DEATH may result if personnel fail to observe safety precautions. Before working
inside the equipment, turn power off and disconnect power cord.

1.3.2 Cautions

To avoid possible damage to the instrument, follow these guidelines:

To properly calibrate the Metrology Well, the “Fan Limit” must be set to “Auto.”

DO NOT leave the sleeve(s) in the instrument for prolonged periods. Due to the high
operating temperatures of the instrument, the sleeves should be removed after each use
and buffed with a Scotch-Brite® pad or emery cloth (see the Maintenance section of
the Users Guide).

Always operate this instrument at room temperature between 5°C and 50°C (41°F
and 122°F). Allow sufcient air circulation by leaving at least 6 inches (15 cm) of
clearance around the instrument. Overhead clearance is required. DO NOT place the
instrument under any structure.

DO NOT interchange inserts between Metrology Well models. The inserts provided
with the instrument as well as any additional inserts ordered are model specic.

Component lifetime can be shortened by continuous high temperature operation.

DO NOT apply any type of voltage to the switch terminals. Applying a voltage to the
terminals may cause damage to the controller.

DO NOT use uids to clean out the well. Fluids could leak into electronics and dam­age the instrument.

DO NOT introduce any foreign material into the probe hole of the insert. Fluids, etc.
can leak into the instrument causing damage.

Before You Start

CE Comments

DO NOT change the values of the calibration constants from the factory set values.
The correct setting of these parameters is important to the safety and proper operation
of the calibrator.

DO NOT slam the probe sheath or sleeves into the well. This type of action can cause
a shock to the sensor and affect the calibration.

The instrument and any thermometer probes used with it are sensitive instruments that
can be easily damaged. Always handle these devices with care. DO NOT allow them
to be dropped, struck, stressed, or overheated.

DO NOT operate this instrument in an excessively wet, oily, dusty, or dirty environ­ment. Always keep the well and inserts clean and clear of foreign material.

The Metrology Well is a precision instrument. Although it has been designed for opti­mum durability and trouble free operation, it must be handled with care. Always carry
the instrument in an upright position to prevent the probe sleeves from dropping out.
The convenient handle allows for hand carrying the instrument.

If a mains supply power uctuation occurs, immediately turn off the instrument.
Power bumps from brown-outs could damage the instrument. Wait until the power has
stabilized before re-energizing the instrument.

The probe and the block may expand at different rates. Allow for probe expansion
inside the well as the block heats. Otherwise, the probe may become stuck in the well.

Most probes have handle temperature limits. Be sure the air temperature above the
Metrology Well does not exceed the probe handle’s temperature limit. If the probe
handle limits are exceeded, the probe may be permanently damaged.

3.2 Setup

NOTE: The instrument will not heat, cool, or control until the “CONT ENABLE”
parameter is set to “On.” Refer to Set-Point Setup on page 16 to set this
parameter.

Place the calibrator on a at surface with at least 6 inches of free space around the instru­ment. Overhead clearance is required. DO NOT place under a cabinet or structure.

Plug the Metrology Well power cord into a mains outlet of the proper voltage, frequency,
and current capability (see Specications for power details). Observe that the nominal
voltage corresponds to that indicated on the back of the calibrator.

Carefully insert the probe sleeve into the well. Probe sleeves should be of the small­est hole diameter possible still allowing the probe to slide in and out easily. Sleeves of
various sizes are available from Fluke Calibration. The well must be clear of any foreign
objects, dirt and grit before the sleeve is inserted. The sleeve is inserted with the two
small tong holes positioned upward.

Turn on the power to the calibrator by toggling the switch on the power entry module.
After a brief self-test, the controller should begin normal operation. The main screen
will appear within 30 seconds. If the instrument fails to operate, please check the power

connection.

The display will show the well temperature, and wait for user input before heating or
cooling to current set-point.

3.4.1 Measure

Stability Limit

NOTE: Metrology Wells should not be expected to operate better than the

stability limit specication set forth in the Specications section of this guide.

Therefore, the minimum setting of the stability limit should not be less than the

stability specication set forth in the Specications section.

The stability limit of the instrument is the parameter which allows the instrument to
notify the user when it has achieved the stability limit set in this parameter. There are
two notications: visual and audible. The visual notication is always active. When
the instrument is operating within the stability limit, the stability parameter on the
main screen will remain highlighted as long as the instrument is within the given
specication, otherwise the parameter will not be highlighted. The audible, if enabled,
alerts the user once per set-point when the instrument achieves the set stability limit.
Use the numeric keys to set the desired stability limit and press “ENTER” to accept
the new stability limit.

Example:

A specic calibration process requires the instrument be operating within ±0.1°C.
“0.1” would be entered into the stability limit parameter. When the instrument is
within ±0.1°C, “STAB: X.XXX°C” will be highlighted and the audible alarm (if
enabled) will notify the user that the instrument is operating within ±0.1°C. Use the
numeric keys to set the desired stability limit and press “ENTER” to accept the new
stability limit.

Stability Alarm (STAB ALARM)

The audible alarm described in “Stability Limit” is turned on or off using this param­eter. Select either “On” or “Off” using the right/left arrow keys and press “ENTER” to
accept the selection.

3.5 SettingtheTemperature

The users guide explains in detail how to set the temperature set-point of the calibrator
using the front panel keys. The procedure is summarized here.

3.5.1 Set-point Setup

1. From the main screen, press “ENTER” once to access the “CONTROL SET
POINT” menu.

2. Press +/- to set a positive or negative temperature. If the “-” symbol is not
present, the temperature is assumed to be positive. Use the number keys to set
the desired temperature. Press “ENTER” to set the temperature and continue
setting up the set-point information. If the other information in the set-point
menu does not need to be edited at this point, press “EXIT” to return to the
main screen

NOTE: Each time the instrument is turned off and back on, the “CONT
ENABLE” parameter is set to “Off”.

3. The “CONT ENABLE” parameter enables or disables active heating or cooling
of the instrument. This parameter must be set to “On” for the instrument to heat
or cool. Using the right/left arrow keys, select “On” to allow the instrument to
heat or cool or select “Off” to disable heating and cooling.

4. The scan rate of the instrument can be set from 0.1 to 99°C/min, however
the actual scan rate is limited by the natural heating or cooling rate of the
instrument. Use the number keys to set the desired scan rate and press
“ENTER”.

When the set-point temperature is changed the controller will switch the thermoelec­tric modules or heater on or off to raise or lower the temperature. The displayed well
temperature will gradually change until it reaches the set-point temperature. The well
may require 5 to 10 minutes to reach the set-point depending on the span. Another 5 to
10 minutes is required to stabilize with ±0.1°C of the set-point. Ultimate stability may
take 15 to 20 minutes more of stabilization time.

3.6 ReferenceProbe(-Rmodelsonly)

The reference probe section of the user manual explains in detail how to set up the
reference probe of the calibrator using the front panel keys. The procedure is summa­rized here.

17

Quick start

Reference Probe (-R models only)

3.6.1 Probe Connection

A PRT is the only type of probe that is supported by the reference thermometer input.
The PRT (RTD or SPRT) probe connects to the reference thermometer input using a
5-pin DIN connector. Figure 1 shows how a four-wire probe is wired to the ve-pin
DIN connector. One pair of wires attaches to pins 1 and 2 and the other pair attaches
to pins 4 and 5 (pins 1 and 5 source current and pins 2 and 4 sense the potential). If a
shield wire is present it should be connected to pin 3.

Figure 1

Probe connector wiring

A two-wire probe can also be used with the reference thermometer. It is connected
by attaching one wire to both pins 1 and 2 of the plug and the other wire to both pins
4 and 5. If a shield wire is present it should be connected to pin 3. Accuracy may be
signicantly degraded using a two-wire connection because of lead resistance.

3.6.2 MeasureTemperature

To make temperature measurements using your probe, the following parameters must
be set up:

1. From the main screen, press the “MENU” button. Access the reference probe
select menu (REF MENU|SELECT). Select “Probe 1” using the right or left
arrow button. Press “ENTER” to accept the probe to be used.

2. To enable “Probe 1,” use the 4 or 5 button to turn the reference probe “On.”
Press “ENTER” to accept the selection.

3. Press the “Setup” soft key (Main Menu: REF MENU|SETUP). In the reference
probe setup menu, select “Probe 1” and press “ENTER”.

5 Controller operation

This chapter discusses in detail how to operate the Metrology Well temperature con­troller or reference thermometer using the front control panel. Using the front panel
keys and liquid crystal display (LCD) the user may monitor the well temperature, set
the temperature set-point in °C or °F, monitor the heater output power, set the cutout
set-point, set the operating parameters, and congure the communication interface. A
diagram of the full menu structure can be found at the end of this section. When ac­tive, menu keys are selected using the soft keys (F1-F4).

5.1 Main Screen

Figure 5 Main screen display

The LCD on the front panel allows direct viewing of the control temperature (actual
well temperature), reference thermometer temperature, heating or cooling power, cur­rent set-point information and current program information. The temperature displayed
is either in °C or °F. The displayed temperature units can easily be changed by press­ing the C/F key on the front panel.

CONTROL TEMPERATURE

This is the temperature of the block as measured by the control sensor. The controller
heats or cools the block to force the control temperature equal to the set-point.

REF TEMPERATURE

This is the temperature measured by an external reference thermometer attached to the
Probe input. It can be displayed in large digits by setting the focus using the left and
right buttons or the FOCUS menu function.

the main screen.

31

Controller operation

Main Menu

SETPOINT

The Setpoint (Set-point) parameter can be set to any value within the range and with
resolution as given in the specications. Be careful not to exceed the safe upper tem­perature limit of any device inserted into the well. The soft cutout should be properly
adjusted to help prevent this occurrence.

CONT ENABLE

NOTE: Each time the instrument is turned off and back on, the “CONT
ENABLE” parameter is set to “Off”.

The Cont Enable (Control Enable) parameter controls whether the instrument heats or
cools. This parameter must be set to “On” for the instrument to heat or cool. Use the
right or left arrow keys to select “On” (the instrument heats or cools) or “Off” (dis­ables heating and cooling).

SCAN RATE

The Scan Rate parameter can be set such that when the set-point is changed, the Me­trology Well heats or cools at a specied rate (degrees per minute) until it reaches the
new set-point.

The scan rate can be set from 0.1 to 500 °C/min (0.2 to 900 °F/min). However, the
maximum scan rate is limited by the natural heating or cooling rate of the instrument,
which is often less than 100 °C/min, especially when cooling.

The scan rate can be adjusted using the numeric keys. Once the scan rate has been set,
press “ENTER” to set the new scan rate.

5.2.1.4 Cutout

Figure 11 CUTOUT SETTINGS menu

The Cutout (CUTOUT SETTINGS) menu allows the user to set the cutout temperature
and to reset the cutout from the display. The cutout temperature is programmable by
the operator from the front panel of the controller. As a protection against software or
hardware fault or user error, the calibrator is equipped with the adjustable cutout de­vice that shuts off power to the heat source if the well temperature exceeds a set value.
This feature protects the instrument and probes from excessive temperatures.

If the cutout is activated because of excessive well temperature, power to the heat
source shuts off and the instrument cools. The heat source remains in cutout mode
and active heating and cooling is disabled until the user manually resets the cutout. If
the over-temperature cutout has been triggered, the instrument displays “CUTOUT”
above the duty cycle bar graph, which indicates a cutout condition. The instrument
remains in cutout mode until the temperature is reduced and the cutout is reset. The
well temperature must drop a few degrees below the cutout set-point before the cutout
can be reset.

For safety reasons, the cutout only has one mode — manual reset. Manual reset mode
means the cutout must be reset by the operator after the temperature falls below the
set-point.

To quickly access the reset cutout function press the “EXIT” key from the main

screen.

CUTOUT

The Cutout parameter can be set to any temperature over the range of the instrument.
The cutout should be set within 5-10° of the safety limit of the equipment being cali­brated or used with the Metrology Well.

917X Series Metrology Wells

RESET CUTOUT

If the Metrology Well exceeds the temperature set in the soft cutout menu or if it
exceeds the maximum operating temperature of the instrument, a cutout condition
occurs. If this happens, the instrument enters cutout mode and will not actively heat or
cool until the user accesses this parameter and selects “Yes”.

CUTOUT ALARM

The Cutout Alarm parameter can be set to ON or OFF. If the Cutout Alarm is ON
when a cutout condition exists, the alarm will sound every 15 seconds.

The Select menu (PROBE SELECT) allows the user to select and enable the probe
that will be used as the reference probe. Parameters for two probes can be stored in the
instrument. If the proper probe is not selected, readings acquired from the thermom­eter will not be accurate. It is important that the proper probe be selected when using
the reference thermometer.

PROBE SELECT

The Select parameter can be set to Probe 1 or Probe 2. The probe being used with the
instrument should be selected from this menu.

ENABLE

The Enable parameter enables or disables the reference thermometer function of the
instrument. This function should be disabled when not in use. In order for the refer­ence probe to function, the reference probe function of the instrument needs to be
enabled from this menu. By selecting “On”, the instrument reads the temperature or
resistance of the probe connected to the reference input on the front of the instrument.

5.2.2.2 Setup

Figure 14 SETUP PROBE menu

The Setup (SETUP PROBE) menu is used to set up the reference probe(s). The instru­ment is only compatible with Platinum Resistance Thermometers (PRTs) with ITS-90
or Callendar Van-Dusen calibrations. No other types of coefcients are supported.

The probe serial number and coefcients can be found on the calibration certicate
that was shipped with the probe. If the probe requires calibration, contact an Autho­rized Service Center to inquire about calibration services offered by Fluke Calibration.

While editing the reference probe serial number, there are two soft keys, BACK and
DONE. BACK acts as a “backspace” key to allow an incorrect digit or character to be
deleted. The DONE key causes the entered serial number to be accepted and returns to
the main reference probe editing window.

SELECT

The SELECT parameter is used to choose which probe is to be setup.

TYPE (ITS-90)

The TYPE parameter can be ITS-90 or Callendar Van-Dusen. The ITS-90 option is for
PRTs calibrated and characterized using the International Temperature Scale of 1990
(ITS-90) equations. Subranges 4, and 7 through 11 are supported. The parameters
that appear when ITS-90 is selected are “Serial” (Serial Number), “RTPW”, “COEF
A”, “COEF B”, “COEF C”, “COEF A4”, and “COEF B4”. These should be set with
the corresponding values that appear on the calibration certicate of the PRT. The
parameter “RTPW” takes the triple point of water resistance, often labeled “R0” or
“R(273.16K)” on the certicate. Parameters “COEF A”, “COEF B”, “COEF C” take
the an, bn and cn coefcients where n is a number from 7 to 11. Parameters “COEF A4”
and “COEF B4” take the a4 and b4 coefcients on the certicate. Any ITS-90 param­eter of the instrument that does not have a corresponding coefcient on the PRT’s
certicate must be set to 0.

37

Controller operation

Main Menu

The following table shows which parameter to set for each of the coefcients that may
appear on the certicate. The example that follows demonstrates how to set the ITS-90
parameters for certain cases.

NOTE: If the certicate has two sets of coefcients, one set for “zero-power”
calibration and one set for 1 mA calibration, use the coefcients for the 1 mA

calibration.

LOW TEMP

The LOW TEMP parameter is the temperature at which the Metrology Well heats or
cools, in order to begin testing if the test is just starting or the temperature at which the
instrument begins to heat to start a cycle.

HIGH TEMP

The HIGH TEMP parameter is the temperature during a cycle at which the Metrology
Well begins to cool at the rate specied in “Ramp Rate”.

APPROACH

The APPROACH parameter determines when the system scan rate is used and when
the switch test ramp rate is used to limit scan rate. During the test, the controller uses
the system scan rate until the temperature is within the approach temperature of either
the high temp or low temp parameters.

RAMP RATE

The RAMP RATE parameter is the rate at which the instrument heats or cools once the
low or high limit is reached. The ramp rate affects the accuracy with which the open­ing/closing of a thermal switch may be measured. The ramp rate should be selected by
the user such that the opening/closing of the switch can accurately be measured.

wires does not matter. Internally, the black terminal connects to ground. The red termi­nal connects to +5V through a 10 kΩ resistor. The calibrator measures the voltage at
the red terminal and interprets +5V as open and 0V as closed.

917X Series Metrology Wells

Main Menu

48

Example:

A thermal switch opens and closes at about 100 °C, but the accuracy, repeatability, and
dead band of the switch need to be veried. The Switch program feature (described in
preceding sections) can be used to test the switch. Test results are shown on the main
screen during and after the test. To set up the test, do the following:

1. Connect the switch wires to the “Switch” terminals on the front of the
Metrology Well (as described previously) and place the switch in the well.
Match the outside diameter of the switch with a similar sized hole of the
Metrology Well insert.

CAUTION: The switch, switch wires, switch components and/or switch
accessories can be damaged if the Metrology Well exceeds their temperature
limits.

2. Set up test “1” at MAIN|PROG MENU|SWITCH MENU|SETUP (see previous
sections for more information on switch test setup). Set LOW TEMP to 80 °C,
HIGH TEMP to 120 °C, RAMP RATE to 1.0 °C, APPROACH to 5.0 °C, and
CYCLES to 3.

NOTE: The LOW TEMP and HIGH TEMP in this example have been set to 100
°C ± 20 °C, but some switches may require a much wider window. The window

gives the instrument an approximation of where the switch will open and close.
If the window of LOW TEMP and HIGH TEMP is too narrow, the switch test
may abort before determining the characteristics of the switch.

NOTE: The APPROACH TEMP, RAMP RATE and CYCLES should be set such

that the highest desired accuracy of the switch temperatures is obtained.

APPROACH should not be set such that (HIGH TEMP – APPROACH) <=

LOW TEMP or “Settings conict” is displayed when trying to start a switch test

and the test will not run.

NOTE: Depending on the mass and/or diameter the switch, there may be a

signicant lag time in how fast the switch heats up or cools with respect to the

block of the Metrology Well. For larger mass and/or diameter switches, a lower
RAMP RATE (0.1-0.5 °C) and a higher APPROACH (5-10 °C) can produce
better results. More cycles may give a better average of when the switch opens
and closes, but a minimum of 2 cycles should be used when running a switch
test.

3. Select test “1” at MAIN|PROG MENU|SWITCH MENU|SELECT using the
arrow keys and press “ENTER”.

4. Start the switch test at MAIN|PROG MENU|SWITCH MENU|RUN by
selecting Run and pressing “ENTER”.

5.2.4.1.2 Meas

Figure 29 MEASUREMENT SETTINGS menu

The Meas (MEASUREMENT SETTINGS) menu is used to set the stability limit and
alarm.

STAB LIMIT

NOTE: The Metrology Well should not be expected to operate better than the

stability specication set forth in the Specications section of this guide.

Therefore, the minimum setting of the stability limit should not be less than the

stability specication.

The STAB LIMIT parameter allows the instrument to notify the user when it has
achieved the stability limit set in this parameter. There are two notications: visual
and audible. The visual notication is always active. When the instrument is operating

917X Series Metrology Wells

Main Menu

52

within the stability limit, the stability parameter on the main screen remains high­lighted once the instrument is within the given specication, otherwise the parameter
is not be highlighted. The audible, if enabled, alerts the user once per set-point when
the instrument achieves the set stability limit. Use the numeric keys to set the desired
stability limit and press “ENTER” to accept the new stability limit.

Example:

A specic calibration process requires the instrument to operate within ±0.1°C. “0.1”
would be entered into the stability limit parameter. When the instrument’s stability
is within ±0.1°C, “STAB: X.XXX°C” is be highlighted and the audible alarm (if en­abled) noties the user that the instrument is operating within ±0.1°C. Use the numeric
keys to set the desired stability limit and press “ENTER” to accept the new stability
limit.

STAB ALARM

The audible alarm described in STAB LIMIT is turned on or off using the STAB
ALARM parameter. Select the either “On” or “Off” using the 4 or 5 arrow keys and
press “ENTER” to accept the selection.

5.2.4.1.3 Oper

Figure 30 OPERATION SETTINGS menu

The Oper (OPERATION SETTINGS) menu allows the user to set up the limit for the
maximum speed of the fan. The FAN LIMIT parameter can be set to Auto, Medium or
Low. The Auto setting allows the instrument to operate at maximum efciency for the
chosen set-point. The instrument may be noisier as the fan moves at different speeds
through the temperature range improving the performance. At low temperature set­tings, the fan operates at its fastest speed. At high temperatures, the fan operates at a
lower speed.

53

Controller operation

Main Menu

NOTE: The Low setting is quieter, but decreases scan rate, reduces low
temperature performance and may prevent the instrument from fully meeting all

specications. The Medium setting falls in the middle of Auto and Low. The

Medium setting does not allow the fan to operate at its fast speed, but does allow
it to operate at slower speed when applicable.

5.2.4.1.4 Comm

Figure 31 COMMUNICATION SETUP menu

The Comm (COMMUNICATION SETUP) menu contains the serial interface param­eters. The parameters in the menu are — PORT, BAUD rate, LF, ECHO, SERIAL
PERIOD and PRINT.

PORT

The PORT parameter can be set to “SERIAL” or “ERRORS”. The serial port referenc­es the serial interface port and its parameters are listed below. The errors port reports
errors obtained by the controller to the screen.

BAUD

The BAUD parameter determines the serial communications transmission rate or baud
rate.

BAUD may be programmed to 1200, 2400, 4800, 9600, 19200, or 38400 baud.

LF

The LF (Line Feed) parameter enables (On) or disables (Off) transmission of a line
feed character (LF, ASCII 10) after transmission of any carriage-return. The “LF”

default setting is on. The line feed parameter can be turned on or off as needed by the

user.

ECHO

The ECHO parameter mode may be set to “On” or “Off”. With echo “On”, any com­mands received by the thermometer via the serial interface are immediately echoed or
transmitted back to the device of origin. With echo “Off”, the commands are executed
but not echoed. The default setting is “On”. The mode may be changed using the left
or right arrow keys and pressing “ENTER”.

SER PER

The SER PER (Serial Period) parameter is the interval at which data is transmitted by
the instrument to a computer through the serial interface. The serial period is the time
period, in seconds, between temperature measurements transmitted from the serial in­terface. For example, if the sample rate is set to 5, the instrument transmits the current
temperature measurement approximately every 5 seconds.

PRINT

The PRINT parameter enables or disables printing the control temperature and power
through the serial port.

NOTE: If PRINT is set to “Off”, samples are not transmitted automatically
through the serial interface.

Digital communication interface

Wiring

6 Digitalcommunicationinterface

The Metrology Well is capable of communicating with and being controlled by other
equipment through the RS-232 digital interface.

With a digital interface the instrument may be connected to a computer or other equip­ment. This allows the user to input the set-point temperature, monitor the temperature,
and access any of the other controller functions, all using remote communications
equipment. The RS-232 serial interface allows serial digital communications over
fairly long distances. With the serial interface, the user may access any of the func­tions, parameters and settings discussed in this section.

6.1 Wiring

The serial communications cable attaches to the instrument through the DB-9 con­nector at the back of the instrument. Figure 39, on this page shows the pin-out of this
connector and suggested cable wiring. To eliminate noise, the serial cable should be
shielded with low resistance between the connector (DB9) and the shield.

Figure 39 RS-232 Wiring

6.1.1 Setup

Before operation the serial interface must rst be set up by programming the BAUD rate
and other conguration parameters. These parameters are programmed within the com­munications menu. The serial interface parameters can be accessed from the main menu
by MENU|SYSTEM MENU|SETUP MENU|COMM. Refer to “Comm” in the Controller
Operation section for more information on the serial interface parameters.

6.1.2 Serial Operation

Once the cable has been attached and the interface set up properly, the controller im­mediately begins transmitting temperature readings at the programmed rate. The serial
communications uses 8 data bits, one stop bit, and no parity. The set-point and other
commands may be sent via the serial interface to set the temperature set-point and view
or program the various parameters. The interface commands are discussed in the “Digital
Interface” section.

6.2 CommandSyntax

Metrology Wells accept commands for setting parameters, executing functions or
responding with requested data. These commands are in the form of strings of ASCII­encoded characters. As far as possible, the Metrology Well command syntax conforms
to SCPI-1994. One notable exception is that compound commands are not allowed as
explained below.

Commands consist of a command header and, if necessary, parameter data. All com­mands must be terminated with either a carriage return (ASCII 0D hex or 13 decimal) or
new line character (ASCII 0A hex or 10 decimal).

Command headers consist of one or more mnemonics separated by colons (:). Mnemon­ics may use letter characters, the underscore character (_), and possibly numeric digits
as well. Commands are not case sensitive. Mnemonics often have alternate forms. Most
mnemonics have a long form that is more readable and a short form consisting of three or
four characters that is more efcient.

A mnemonic may end with a numeric sufx that species one of a set of independent
function blocks such as input channel data paths. If a numeric sufx is omitted when a
particular block must be specied, an error is generated (“Header sufx out of range”).

Query commands are commands that request data in response. Query commands have
a question mark (?) immediately following the command header. Responses to query
commands are generated immediately and placed in the output buffer. Responses are then
transmitted automatically over the RS-232 port. Responses are lost if not read before the
next command is received.

Some commands require parameter data to specify values for one or more parameters.
The command header is separated from the parameter data by a space (ASCII 20 hex or
32 decimal). Multiple parameters are separated by a comma(,).

Metrology Wells do not allow compound commands (multiple commands per line sepa­rated with semicolons). All commands are sequential. The execution of each command is
completed before subsequent commands are processed.

6.4 SerialCommands-AlphabeticListing

Each command description provides the structure (long and short format), a descrip­tion of the command purpose, a command example, an example of what the command
returns (as applicable to query commands), and notes specic to the command. The
following apply to each group of commands:

●

Numeric data, specied by the mnemonic, <num>, uses ASCII characters to
represent numbers. Numbers may contain a plus or minus (‘+’ or ‘-’) sign,
decimal point (‘.’), and exponent (‘E’ or ‘e’) with its sign. If a fractional
component is received when only an integer is required, the number is rounded
to the nearest integer without any resulting error message. The mnemonics DEF,
MIN, and MAX are often acceptable for the default, minimum, and maximum
value respectively. Unit sufxes, such as V or OHM, can be appended to
numeric parameters and are accepted without error but ignored.

●

Unrecognized commands or commands with incorrect syntax or invalid
parameters generate error messages in the error queue.

●

Upper case letters designate syntax that is required when issuing the command.
Lower case letters are optional and may be omitted.

●

indicates a required parameter.

●

[] indicates optional parameters.

●

() indicates a group of parameters that must be used together.

●

For query commands, specifying the MIN, MAX, or DEF parameter causes
the instrument to respond with the minimum, maximum, or default setting

respectively.

●

For set commands, specifying the MIN, MAX, or DEF parameters causes the
instrument to use the minimum, maximum, or default setting respectively.

●

‘|’ indicates alternate parameter values.

●

<n> indicates a number is required.

●

<num> indicates numeric value is required.

●

<prog> indicates a program number (SEQ<n> or SWIT<n>) is required.

●

<bool> indicates a Boolean value (0 or 1) is required. The mnemonics OFF and
ON are also accepted for 0 and 1, respectively.

●

<conv> indicates a conversion mnemonic is required.

●

<param> indicates a parameter name is required.

●

<seri> indicates a serial number is required.

●

<res> indicates a resistance value is required.
