UNI-T UT203 User Manual

UT203:
Change to AC by using average response method. Input sine wave, then adjust
the reading until it is same as the effective value.
UT204:
Combine AC and True RMS response method. Input sine wave to adjust. Non
sine wave must follow the below data to adjust:
Peak factor: 1.4~2.0, add 1.0% on the stated accuracy
Peak factor: 2.0~2.5, add 2.5% on the stated accuracy
Peak factor: 2.5~3.0, add 4.0% on the stated accuracy.
Remove the transformer jaw.
Press to display zero.
Repeat the above 1. procedure.
