Note
[1]
: The integration time is set to 100PLC.
Note
[2]
: Specifications are for the 4-wire resistance function or the 2-wire resistance function using “REL” operation.
If the 2-wire resistance function is used without "REL" operation, add 0.2Ω additional errors.
Note

: Q marks the optional quick test points.
Gain Test
The gain test inspects the accuracy of the multimeter under full range. It is necessary only when a
regular gain offset occurs to a function and range.
1. The DC gain test procedures
(1) Make sure you have carefully read the "Test Conditions".
(2) Connect the input terminals of the multimeter with the calibrator.
(3) Test the functions under different ranges specified in Table 2-2 one by one. Set the
integration time to 100PLC. Unless otherwise noted, turn off all the math operations.
(4) Input the signals specified in Table 2-2 using the calibrator and compare the test results
with the limits in the table (make sure the output of the calibrator is built adequately).
