INSTALLATION
There is no need to remove the meter from its case to complete the
installation, wiring, and setup of the meter.
Unpacking
Remove the meter from box. Inspect the packaging and contents
for damage. Report damages, if any, to the carrier.
If any part is missing or the meter malfunctions, please contact your
supplier or the factory for assistance.
Panel Mounting
• Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm
x 45 mm). Refer to Mounting Dimensions, page 28 for more details.
• Clearance: allow at least 4" (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-off
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.

Connections
All connections are made to removable screw terminal connectors
located at the rear of the meter.
Use copper wire with 60°C or 60/75°C insulation
for all line voltage connections. Observe all safety
regulations. Electrical wiring should be performed
in accordance with all applicable national, state,
and local codes to prevent damage to the meter
and ensure personnel safety.
Connector Labeling
The connectors label, affixed to the meter, shows the location of the
connectors. It also identifies the location of the RTD/TC selector switch.

Power Connections
Power connections are made to a two-terminal connector labeled
POWER on Figure 2. The meter will operate regardless of DC polarity
connection. The + and - symbols are only a suggested wiring convention.

SETUP AND PROGRAMMING
• There is no need to recalibrate the meter
when first received from the factory.
• The meter is factory calibrated prior to ship-
ment, for all input types, in degrees Fahrenheit. The calibration equipment is certified to
NIST standards.
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, Figure 2.
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.

or RTD (rtd) inputs.
If RTD is selected, the display shows A385 or A392. Select the coefficient to match the RTD sensor, either 0.00385 (European curve) or
0.00392 (American curve).
If TC is selected, scroll through the thermocouple types and select the
type matching the TC sensor.
The input signal must be connected to the appropriate input terminals
and the RTD/TC selector switch must be set accordingly, see Figure 4
on page 11.
For thermocouple inputs, allow at

Programming the Meter (prog)
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.
Recalibrating Temperature Inputs (Cal)
Remember, the meter is calibrated at the factory prior to shipment. Recalibration is recommended at least every twelve months.
The Calibration (CAL) menu is used to recalibrate the thermocouple and
RTD inputs.
Allow at least 30 minutes warm-up time be-
fore performing recalibration procedure to
ensure specified accuracy.

Error Message (Err)
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.

Recommended 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), see page
11.
2. Set up the meter to accept the selected input (e.g. type J T/C),
see page 19.
3. Set up the meter to display temperature in degrees Fahrenheit,
see page 20.
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 mes-
sage CJr, indicating that the meter is sensing the cold junction
reference. This completes the recalibration procedure for the
selected input.

Setting Up the Password (pass)
The Password menu is used to program a four-digit password to prevent unauthorized changes to the programmed parameter settings.
Locking the Meter
Enter the Password menu and program a four-digit password.

Values, page 18.
Record the password for future reference. If appropriate, it may be recorded in the space provided.

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
