Step 4:
Set the integration time.
The setting of the integration time affects the measurement speed and measurement accuracy. The longer the
integration time, the higher the accuracy but the slower the measurement. 1PLC, 10PLC, 100PLC can inhibit the
power supply noise. Selecting 100PLC can provide the best noise rejection, but at a slower rate.
Step 5:
Auto Zero.
Choose whether to turn on the automatic zeroing. Auto-zeroing results in more accurate test results, but requires
more test time. With auto zero enabled, the multimeter internal offset is measured each time the input signal is
measured. Then subtract the offset from the previous reading. This avoids the effect of the offset voltage on the
input circuit of the digital multimeter on the measurement accuracy. In the case of auto-zeroing, the digital
multimeter measures the offset once and subtracts the offset from all subsequent measured parameters. The DMM
makes a new offset measurement each time you change the function, range, or integration time.
