Remarks:
[1] The rate of reading is “Slow”.
[2] Specifications are for “REL” operation under 4-waire or 2-wair resistance measuring. If “REL”
operation is disabling under 2-wair resistance measuring, 0.2 Ω additional errors are needed.
[3] Q denotes optional quick test point.
Gain Test
This test is used to inspect the accuracy of the device in full range, and which is
required only when regular offsets happened to function or range.
1. Verification procedure of DC Gain:
(1) Read “Testing Conditions” carefully before start.
(2) Connect the input terminal of the meter with calibration instrument.
(3) Test the functions and ranges listed in Table 3-3 item by item. And then set
the rate of reading as “Slow” and disable all the math operations. When
measure DC Voltage or DC Current, please shut off “filter”.
(4) Input signals listed in Table 3-3 using calibration instrument and compare the
test results with test limits listed. (Make sure that the calibration instrument
is in a state of output )
