Overview
There are no jumpers involved in the setup process
of the meter. The RTD/TC selector switch, located
between the SIGNAL and RJ11 connectors, must
be set accordingly for the meter to accept RTD or
thermocouple inputs. Setup and programming is
done through the front panel buttons. After power
and signal connections have been completed and
verified, apply power to the meter.

Installation
There is no need to remove the meter from its case
to complete the installation, wiring, and setup of
the meter.
Panel Mounting Instructions
• Prepare a standard 1/8 DIN panel cutout -
3.622" x 1.772" (92 mm x 45 mm). Refer to
Figure 1. 1/8 DIN Panel Cutout Dimensions
below for more details.
• Clearance: allow at least 4.0" (102 mm) behind
the panel for wiring.
• Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).
Recommended minimum panel thickness to
maintain Type 4X rating: 0.06" (1.5 mm) steel
panel, 0.16" (4.1 mm) plastic panel.
• Remove the two mounting brackets provided
with the meter (back-o󰀨 the two screws so
that there is ¼" (6.4 mm) or less through the
bracket. Slide the bracket toward the front of
the case and remove).
• Insert meter into the panel cutout.
• Install mounting brackets and tighten the
screws against the panel. To achieve a proper
seal, tighten the mounting bracket screws
evenly until meter is snug to the panel along its
short side. DO NOT OVER TIGHTEN, as the
rear of the panel may be damaged.

Programming the Meter
It is very important to read the following information, before proceeding to program the meter:
• There is no need to recalibrate the meter when first received from the factory.
• The meter is factory calibrated prior to shipment, for all input types, in degrees Fahrenheit. The calibration
equipment is certified to NIST standards.
The Program menu contains the Calibrate menu.

Functions Description
Error Message
An error message indicates that the calibration process was not successful. After the error message is displayed,
the meter reverts to input 1, allowing the appropriate input signals to be applied.
The error message might be caused by any of the following conditions:
1. Input signal is not connected to the proper terminals or it is connected backwards.
2. Wrong signal selection in Setup menu.
3. Minimum input span requirements not maintained.
4. Input 1 signal inadvertently applied to calibrate input 2.
Minimum Input Span
The minimum input span is the minimum difference
between input 1 and input 2 signals required to
complete the calibration of the meter.
Input range Input 1 & input 2 span
TC 100°F (56°C)
RTD 50°F (28°C)

Calibration Points
To recalibrate the meter, it is recommended to
use the Fahrenheit scale; this will give a greater
degree of accuracy to the calibration. The scale can
be changed to the Celsius scale after calibration
is completed. The meter will display temperature
accurately in any scale. The following table shows
the recommended low and high calibration points
for all types.

Recalibration Procedure
for Temperature Inputs
1. Connect signal to the meter using the
appropriate wire (e.g. type J thermocouple
wire to recalibrate type J input)
2. Set up the meter to accept the selected
input (e.g. type J T/C)
3. Set up the meter to display temperature in
degrees Fahrenheit
4. Apply signal corresponding to input 1 (e.g.
32°F) and program display 1 to read 32.
5. Apply signal corresponding to input 2 (e.g.
1182°F for type J) and program display 2
accordingly.
6. After the meter accepts input 2, the display
flashes the message CJr, indicating that the
meter is sensing the cold junction reference.
This completes the recalibration procedure
for the selected input.
Maximum/Minimum
Readings
The main function of the front panel buttons during
operation is to display the maximum and minimum
readings reached by the process.
1. Press Up arrow/Max button to display
maximum reading since the last reset/
power-up.
2. Press Up arrow/Max again to display the
minimum reading since the last reset/
power-up.
3. Press Enter/Ack to hold Max/Min display
reading, the meter will continue to track new
Max/Min readings.
4. If Enter/Ack is not pressed, the Max/
Min display reading will time out after ten
seconds and the meter will return to display
the actual reading.
5. Press Right arrow/Reset button to reset
Max/Min while reading is being displayed.
Max/Min display readings are reset to actual
reading.

Password
Unlocking the Meter
If the meter is password protected, the correct password must be entered in order to make changes to the
parameter settings.
Entering the correct four-digit number sets the password to 0000, disabling the protection.
Changes to the programmed parameter settings are allowed only with the password set to 0000.
If the password entered is incorrect, the meter displays LoCd (Locked) for about two seconds, then it returns to
Run Mode. To try again, press Enter/Ack while the Locked message is displayed.
Forgot the Password?
The password may be disabled by the following procedure:
1. Note display reading prior to pressing the Menu button. Ignore decimal point and sign.
2. Access the Password menu, add 2 to the noted reading and enter that number as the
password. (e.g. display reading = -1.23, password = 0125).
