Compact voltage detector (non-contact phase meter) - chemical type MS8902B from MASTECH, designed for easy detection of AC voltage by non-contact method, as well as metal at a distance of up to 20 mm. Range from 20 to 1000 VAC. Automatic shutdown. Sound and light signaling.
1. Never exceed the limit values indicated on the scale for each measurement range.
2. Do not touch the non-insulated probe parts when measuring.
3. Never use the instrument to measure a voltage higher than 600 VAC.
4. When the value of the measured parameter is unknown, the instrument is set to the maximum range.
5. Before selecting another measurement parameter, remove the probes from the previous measurement.
6. When measuring impulse power supply, be aware that high impulse values can damage the unit.
7. The safe touch voltage is up to 60 VDC, 30 VAC rms.
8. Never measure impedance in a circuit with a supply voltage included. In the resistance measurement mode, do not measure the voltage. In the current measurement mode, do not measure the voltage
