Precautions
1.You must wait for the discharge to end and the alarm sound stops before removing the
wire, otherwise it is dangerous.
2. When measuring the no-load tapping transformer, the discharge must be reset before
tapping, and the tapping point can only be switched after the alarm stops.
3. Refer to the test range when selecting the current, and must not use over range or
under range. When using over-range, the instrument is always in the "charging" state
because the current cannot reach the set value.
4. Pay attention to the range when using the magnetic method. Because the high-voltage
coils are connected in parallel and in series, 1.5 times the resistance of the high-voltage
coil is added to the entire test loop, which should be included when selecting the range. If
the output current cannot reach the set value or the output current is unstable if the range
is exceeded.
5. When the short contacts of the three wires of the magnetic assist method are removed
after the discharge is completed, there may be residual current, and may spark and
discharge when removed, which is a normal phenomenon.
