    Step 5: Auto Zero. 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.

Signals greater than 300 V (RMS) or 1 A (RMS) can cause self-heating of the signal conditioning components. These errors are included in the instrument's specifications. Internal temperature changes caused by self-heating may cause additional errors in other functions or ranges.

    5.2 Handler Interface Many instruments are used in industrial control. In order to better use the device with opto-coupled control signals, the Handler interface is added to facilitate the use of the instrument on the production line.
