Frequency And Duty Cycle Measurements; Temperature Measurement; Non-Contact Voltage Detection (Ncv); Auto Off - Multimetrix DMM53 Manual Del Usuario

„ The measurement is displayed. Wait for the measurement to stabilize.

2.5. FREQUENCY AND DUTY CYCLE MEASUREMENTS

„ Connect the red lead to the + terminal and the black lead to the COM terminal
„ Set the switch to Hz.
„ Use the Hz% key to select the desired function: Hz or %.
„ Place the test probes on the element to be tested and maintain a firm contact.
„ The measurement is displayed.

2.6. TEMPERATURE MEASUREMENT

„ Connect a K thermocouple between the + and COM terminals.
„ Set the switch to °C.
„ Place the end of the thermocouple on the object or in the environment to be measured.
„ The measurement is displayed. Wait for the measurement to stabilize.

2.7. NON-CONTACT VOLTAGE DETECTION (NCV)

The instrument can detect an AC voltage greater than or equal to 110V with respect to ground.
„ Disconnect the leads.
„ Set the switch to any position except OFF.
„ Keep the NCV key pressed and move the top of the instrument close to the conductor.
„ The presence of the voltage is indicated by the blinking of the indicator and by the audible signal.
The absence of a voltage indication in the NCV function does not mean that there is no voltage. To
confirm the absence of a voltage, use a VAT.
The presence of other voltages nearby can trigger non-contact voltage detection.

2.8. AUTO OFF

To save the batteries, the instrument switches itself off automatically after 30 minutes if the user has not
shown signs of being present by turning the switch or pressing a key.
To suppress auto off, press the SLT key while turning the switch when starting up.
