VI-3.1. Direct voltage measurements
- Depress pushbutton
V=
- Select the correct measuring range
- Connect the test voltage to terminals "0" and "VQ"
Notes:
- The polarity indicator indicates the polarity at terminal "МО" with respect to
terminal "0".
- Maximum permissible voltage between terminals "VQ" and "0" is 1000 Vd.c. or
600 Va.c.
(50 Hz).
М1-3.2. ЕНТ voltages up to 30 kV with probe PM 9246
- Depress pushbutton V—
- Connect the probe to terminals "0" and "VQ" (terminals "0" and "_L" should be interconnected)
- Connect the earthing clip of the probe to a proper earth
- Select the 10 MQ range on the probe
- With the range selector the following ranges are possible.
Range selector to position
HT range
2N
2 kV max.
20 V
20 kV max.
200 V
30 kV max. (see note)
Notes:
- Maximum permissible d.c. voltage 30 kV (range end is 200 kV)
- The position of the decimal point should be observed.
VI-3.3. Alternating voltage measurements
- Depress pushbutton VA
- Select the correct measuring range
- Connect the test voltage to terminals "0" and "МО".
Note:
- Maximum permissible voltage between terminals "VO" and "0" is 500 Vd.c. or
600 Va.c.
(50 Hz)
VI-3.4. UHF voltages with probe type PM 9210 and T connector type PM 9212
- Depress pushbutton Vas
|
- Connect the probe to terminals "0" and "VQ" with the earthing pin to "0" (terminals "0" and
1 should be interconnected).
Notes:
- The maximum permissible voltage on the probe (with attenuator) is 200 Vrms
superimposed on 500 V 4.с.
- The correction factor on the calibration curve of the probe should be taken
into acount.
