3. Activate mV AC measuring mode for continuity test: press [] 3
times.
4. Switch on the clamp meter adapter.
- LED indicates readiness for operation.
5. Place the cables being measured centrally within the clamp.
- The measured value is shown on the LC display.
7.4. Measuring resistance, capacitance,
continuity and diode test
WARNING
Serious risk of injury to the user and/or destruction of the instrument
during resistance testing.
> Test object must be de-energized.
External voltages will distort the measurement result.
Resistors and semiconductors in parallel with the diode will
distort the measurement result.
> Prior to the measurement, make sure that capacitors are discharged.
✓ Instrument is switched on.
7.4.1. testo 760-1
Manual measuring mode
1. Connect test leads: black test lead to the COM jack; red test lead to the
V/Ω/diode/capacitance jack.
- The instrument is in
Ω mode.
2. Switch between resistance, capacitance, continuity and diode test:
press [] <1 s.
- The measured value is shown on the LC display.
7.4.2. testo 760-2/-3
Automatic measuring mode
Automatic detection for resistance/capacitance in the following
range:
• 0.0 ohms to 6.000 mohms
• 0.500 nF to 600.0 µF
Change to manual measuring mode for the remaining measuring
range.
1. Connect test leads: black test lead to the COM jack; red test lead to the
V/Ω/diode/capacitance jack.
- The instrument is in AUTO V mode.
2. Disable AUTO RCDC measuring mode: press [] <1 s.
3. Connect test leads to the test object.
- The instrument detects resistance, continuity, diode and capacitance,
and automatically adjusts the measuring range.
- The measured value is shown on the LC display.
