Ac Voltage Measurements; Dc Voltage Measurements - Westfalia 99 31 54 Instruction Manual

AC Voltage Measurements

1. Connect the black measuring cable to the COM input (6)
and the red measuring cable to the V/Ω/
2. Then set the rotary function switch (3) to the desired
measuring range (600 V~).
3. Connect the measuring tips parallel to the circuitry and read
the voltage from the display.
Please make sure not to exceed 600 V.
Range Resolution
600 V~ 1 V
Input impedance: 9 MΩ

DC Voltage Measurements

1. Connect the black measuring cable to the COM input (6)
and the red measuring cable to the V/Ω/
2. Then set the rotary function switch (3) to the desired
measuring range (600 V
3. Connect the measuring tips parallel to the circuitry and
observe correct polarity (red to plus; black to minus) and
read the voltage from the display.
4. If a minus symbol (A) appears on the display (4), correct the
polarity.
Please make sure not to exceed 600 V.
