Operation
This section gives examples of how to connect and use the
instrument. Before you start:
• Read and understand the “Safety” section.
• Do not use a damaged instrument.
Operation - Thermocouple connections
Attach the thermocouple wires to the applicable
thermocouple mini-connector (Figure 1). The wider blade is
the negative.
Then attach the connector to the instrument.
Operation - Communications port connections
Use the communications port (A1 - item [9]) to attach an
IDOS Universal Measurement Module (UMM).
When you attach the cable from a UMM (Figure 7/8), the
instrument automatically changes the menus to give you
all the applicable options (Table 2/3).
Operation - Measure thermocouple values
To measure the temperature or mV values of a
thermocouple:
1. Connect the instrument (Figure 1) and, if necessary,
adjust the Set Up (Table 1).
2. Select a T1 or mV input task from Select Task (Table 2/3)
and, if necessary, adjust the Settings (Table 4).

temperature or mV values of a thermocouple
Operation - Change the output values
When the output operation is set up (Table 5), use one of
these procedures to change the output values:
