7. When measuring the no-load voltage-regulating transformer, switch the gears after the
discharge indication alarm sound stops.
8. During the test, it is forbidden to move the test clip and power supply line.
III.Performance characteristics
1. The instrument has large output current and high voltage.
2. Dual-channel measurement, measuring two resistance values at the same time.
3. It has a complete protection circuit and strong reliability.
4. Horizontal structure, convenient for on-site operation of transformer factory.
5. With sound discharge alarm and clear discharge indication, reduce misoperation.
