3. Select the appropriate current range according to the size of the resistance to be
measured.
The user can press [Range] to select a measuring range or use the front panel keys
quickly select a range. The automatic range automatically selects a range for the
measurement based on the input. Compared to the manual range, the automatic range is
more convenient, but the measurement speed is slower.

4. Set the relative value
Turn on or off the relative operation function. When the relative operation is turned on, the
displayed number is the actual measured value minus the set relative value. (For details on
how to set the relative value, refer to the section "Mathematical Operation Function" in this
chapter).
5. Set the integral time
Press the [Integral time] to select an integral time for the measurement. Selecting 100
PLC, it provides the best noise rejection and resolution, but the slowest measurement
speed.
6. Set automatic zeroing
Press the [Auto Zero] to enable or disable this function. Auto zero provides the most
accurate measurements, but requires additional time to perform the zeroing
measurement. When auto-zero is enabled, the multimeter will take an internal
measurement of the offset after each measurement. This measurement will subtracted
its measured value from the previous reading. In this way, the offset voltage on the input
circuit of the multimeter affect the measurement accuracy can be avoided.
