Fig 4.1 12 kV DC High Tension Probe
CAUTION
When measuring high voltage, observe the following
safety precautions to avoid potential risks.
· Make sure that the grounded leads are firmly connected.
· Check the probes (must not be wet or contaminated with
foreign materials) prior to measurement to avoid possible
risks.
Wear a pair of gloves (e.g. rubber gloves) to ensure safety.
· Avoid measuring high voltage on the power line to prevent
possible hazards.
1. This probe is intended to be used in the adjustment of high
voltage electronic equipments such as television.
However, the high voltage measurement on power lines is
dangerous, and must be avoided.
2. Firmly connect the Protective Resistance Box of the high voltage
probe to the terminal of the tester so that the probe may come to
the
V.A. Ω
terminal side of the tester (and the clip adapter to the
COM- terminal side).
3. Set the polarity select switch to
+DC,AC, Ω
and the measuring
range select switch to the “DC 1.2 V” range.
Then, read the value on the [DC] scale.
