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 insulat ion
for all line voltage connections. Observe all safety
regulations. Electrical wiring should be performed
in accordance with all applicable natio nal, state,
and local codes to prevent damage to the meter
and ensure personnel safety.

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. T he
RTD/TC selector switch, located bet ween 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 ver ified,
apply power to the meter.

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 c ertified
to NIST standards.
The
Program menu contains the Calibrate menu.
)
Recalibrating Temperature Inputs (
)
Remember, the meter is calibrated at the factory prior to shipment. Recalibration is recommended at least every twelve months.
The

Err
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.

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. T he scale
can be changed to the Celsius scale after calibration is completed. The
meter will display temperature accurately in any scale. The follo wing 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 message
CJr, indicating that the meter is sensing the cold junction
reference. This completes the recalibration proced ure for the
selected input.
