Using the standard test leads (copper wires)

Hand-tight the terminal screws
before plugging the test leads in.
Compensation in this case is required
to offset the cold junction
compensation microvolts generated by
the instrument under calibration.
For this we need to measure the
temperature at the instrument
terminals. Instrument terminal
temperatures can be measured by
either a hand-held thermometer or a
remote temperature probe.
• Hand-held thermometer
(not supplied by GE)
Read the thermometer while holding it
close to the instrument terminals.
Select MANUAL and open the screen
to fill out the obtained reading. Press
EXE to enter.
Note that in this mode temperature
changes at the instrument terminals
can easily create calibrations errors.
• Remote temperature probe
(optional)
Plug-in the Pt100 probe as shown and
select EXTERNAL in the menu.
Position the sensor tip as close as
practically possible to the instrument
terminals.
