5.6 Continuity testing
Requirements
• Please observe the requirements for measuring [}page26].
• Approved safety measuring lines
• Continuity test [}page24]
• Please observe the figure for continuity testing. [}page31]
Procedure
1. Set the rotary switch of the device to switch position “ ”.
2. Connect the safety measuring lines to the device [}page27].
3. Press the “ACHFR/ DCAZERO” key to set the desired “Continuity test” function (“ ”
symbol).
4. Bring the safety measuring lines into contact with the measuring points.
When the buzzer sounds (acoustic signal), the line resistance between the COMjack and
the “+”jack falls below the value of 20to200Ω.
5.7 Capacitance measurement
Requirements
• Please observe the requirements for measuring [}page26].
• Approved safety measuring lines
• Capacitance ranges [}page25]
NOTICE
Capacitors not discharged
Measuring the capacitance at capacitors that are not fully discharged can damage the device.
• Discharge the capacitors completely before measuring the capacitance.
• Do not apply any voltage to the jacks of the device (“COM” and “+”) during the capacitance
measurement.
• Please observe the figure for capacitance measurement [}page31].
Procedure
1. Set the rotary switch of the device to switch position “ ”.
2. Connect the safety measuring lines to the device [}page27].
3. Press the “ACHFR/ DCAZERO” key to set the desired “Capacitance measurement”
function (“n” symbol).
4. Bring the safety measuring lines into contact with the discharged capacitor– observing
correct polarity– and read the measured value on the digital display.
