Sanwa CX506a, Инструкция по эксплуатации, Страница: 48 / 60

1) Application
The probe is suitable for measuring voltage of high impedance
circuits, such as CRT anode voltage of TV sets.
6-9 DC High Voltage measurement (HV) (Optional HV Probe)
Max. measurement value 30 kV DC
1.The probe is designed for the measurement of very small
direct current circuit. Never use the probe to measure
high voltage in power lines, such as transmission and
distribution lines; it is very dangerous.
2. Never apply input signals that exceed 30 kV.
3. Be sure to disconnect the test pins from the circuit when
changing the function.
4. Always keep your fingers behind the finger guards on the
probe when making measurements.
WARNING
2) Measuring range:
HV PROBE (DC 120 mV)
3) Measurement procedure
①
Shift the polarity
reversal switch to ＋
position.
②
Connect the black plug of
the HV Probe to the −
input terminal and the
red plug to the ＋ input
terminal.
③
Set the function/range
selector to HV PROBE position.
④
First, connect the clip (black) of the probe to the earth line ( − ) in
the circuit to be measured, and then apply the measuring pin on
the probe body to your measuring point.
⑤
Read the pointer on V ・ A (0 〜 30) scale as kV.
⑥
After measurement, remove the measuring pin from the
measured circuit, and then remove the clip.
6-10 End of Measurement
When measurement is end, be sure to return the function/range
selector to the OFF position.
