ISOLATED MILLIVOLT THERMOCOUPLE SIMULATOR 41-761
VERIFICATION TEST RESULTS
For convenience, Tables 7.2 to 7.4 on the following pages are provided for a means of recording results for one
channel of each model.
Adjustment Procedure
In the unlikely event that adjustment of the 41-761 is required we recommend returning it to Pickering Interfaces.
Adjustment of the 41-761 requires the use of a high performance DMM and an automated program in order to
maintain its accuracy in the event of an adjustment being required to improve performance.

● If the full functionality of the module is to be checked, subsequent voltages and ranges can also be checked in
turn, as dened in table 7.1.
● After a given channel is tested it is recommended that the clear card function is used to ensure each channel
is left in the open state, ensuring it does not affect subsequent channel testing.
● Repeat across all channels as required.
