UNI UT213A B C INSTRUCTIONS 3 Measuring of AC Voltage See Figure 4 1 Insert the red probe into V jack and black one into COM jack 2 Switch to AC voltage gear position press SELECT key to select AC voltage measurement and connect in parallel the probe to the power supply or load to be tested 3 Read the AC voltage value directly from the display Caution Do not input voltage of higher than AC 600V It is possible to measure higher voltage but at the risk of meter damage It is especially necessary to be cautious about electric shock when measuring high voltage The probe shall be disconnected from the tested circuit after all measuring operations UT213A when the input voltage is higher than AC 1000V the meter will directly display OLI UT213B C when the tested voltage is higher than the safety voltage of AC 30V the LCD will display HV warning prompt in case of over voltage input if the voltage is beyond the range of AC 600V range gear the meter will automatically give out interrupted buzz for warning AC conversion is a true virtual value response mode through AC coupling which is corrected through sine wave input Therefore the accuracy of non sine wave must be adjusted in accordance with the following If wave crest factor is 1 4 2 0 the accuracy is 1 0 If wave crest factor is 2 0 2 5 the accuracy is 2 5 Figure 4 19 20
