| Safety Voltage Check |
Voltage measurement: 0.1 V - 600 V a.c; the meter is RMS calibrated and average responding
Safety voltage indicator: Indicates the presence of d.c. voltages.
Scaling is not the same as the a.c. meter. True d.c. voltage equals
scale reading divided by 2.22
Accuracy: 2.5% of full scale |
