This manual describes how to operate the testo 760 digital multimeter.
This manual provides instructions for safely operating the Testo 760 digital multimeter. It covers measurement functions including voltage, current, resistance, capacitance, frequency, and temperature (with optional adapters). Safety precautions are emphasized, including proper use in CAT III or CAT IV circuits and warnings against use in explosive environments. The guide also details control key functions, display features, and maintenance procedures.
The multimeter comes in two variants: testo 760-1 for basic measurements and testo 760-2/-3 for extended functions including duty cycle and temperature. Both models include safety ratings, overload protection, and battery management features. Calibration and service instructions are included for professional use only.
| Overload Protection | 10 A fuse for testo 760-2/-3 |
|---|---|
| Battery Capacity Display | 100–30%, 30–15%, 15–2% (flashes), 2–0% (auto-off) |
Voltage, resistance, continuity, diode, capacitance, frequency, duty cycle, and temperature (with optional thermocouple adapter).
Briefly press the Voltage key to toggle between AC and DC modes. Long press returns to AUTO mode.
