PRECAUTIONS FOR USE

This instrument is compliant with safety standard IEC61010-2-033 and the leads are compliant with IEC61010-031, for voltages up to 600V in measurement category III.

■ Failure to observe the safety instructions may result in electric shock, fire, explosion, and destruction of the instrument and of the installations.
■ The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be taken in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument.
If you use this instrument other than as specified, the protection it provides may be compromised, thereby endangering you.
■ Do not use your instrument on networks of which the voltage or category exceeds those stated.

■ Observe the environmental conditions of use.

■ Do not use the instrument if it seems to be damaged, incomplete, or poorly closed.

■ Before each use, check the condition of the insulation on the leads, housing, and accessories. Any item of which the insulation is deteriorated (even partially) must be set aside for repair or scrapping.
■ Use only the leads supplied. The use of leads of a lower voltage rating or category limits the use of the combined instrument + leads to the lowest category and service voltage.
■ Do not use the instrument in an explosive or dust-laden atmosphere.
■ When handling the test probes, keep your fingers behind the physical guard.
■ Use personal protection equipment systematically.
■ All troubleshooting and metrological checks must be done by competent, accredited personnel.

1.3. DISPLAY UNIT

When the display unit indicates OL, it is because the quantity measured lies outside the measurement range.

1.4. PRESENTATION OF THE INSTRUMENT

The DMM53 is an easy-to-use hand-held digital multimeter.

It can measure AC and DC voltages, AC and DC currents, resistances, capacitances, frequencies, and temperatures. It can also be used to determine duty cycles, diode voltages, and continuities and for non-contact voltage detection (NCV).

+ terminal.

2.1. VOLTAGE MEASUREMENT

■ Connect the red lead to the + terminal and the black lead to the COM terminal.
■ Set the switch to V.
■ Place the probe tips on the element to be tested, starting with the black probe tip, and maintain firm contact.
■ The voltage is displayed.
■ At the end of the measurement, disconnect the + terminal first, then the COM terminal.

The SLT key is used to choose to display the AC voltage only or the DC voltage only. To measure a DC voltage, first check that the AC voltage is zero.

2.2. CURRENT MEASUREMENT

Before each current measurement, check the fuses.

■ Short-circuit the + and 10A terminals and make a continuity measurement. If the result is 0, the fuse in the 10A terminal is OK. If the result is OL, the fuse (F2) must be replaced.
■ Measure a known current (<400mA) between the + and COM terminals. If the result is 0, the fuse (F1) must be replaced.

To make a current measurement:

■ Cut off power to the device to be tested and discharge all high-voltage capacitors.
■ Set the switch to A, mA or A, depending on the value of the current to be measured.
■ Connect the red lead to the 10A terminal or to the + terminal and the black lead to the COM terminal.
■ Place the test probes on the element to be tested and maintain a firm contact.

■ Power up the device to be tested and read the measurement.

2.3. RESISTANCE, DIODE, AND CONTINUITY MEASUREMENTS

■ Connect the red lead to the + terminal and the black lead to the COM terminal
■ Set the switch to .
- Cut off power to the device to be tested and discharge all high-voltage capacitors.
■ Use the SLT key to select the desired function: Ω, ➤ or ⚪.
■ Place the test probes on the element to be tested and maintain a firm contact. For diode voltage measurements, place the red probe tip on the cathode and the black probe tip on the anode.
■ The measurement is displayed.

For low resistance measurements, measure the resistance of the leads by short-circuiting the probe tips. Subtract the value so found from the low resistance measurements.

2.4. CAPACITANCE MEASUREMENT

■ Connect the red lead to the + terminal and the black lead to the COM terminal
■ Set the switch to .
■ Cut off power to the device to be tested and discharge all high-voltage capacitors.
■ Place the test probes on the element to be tested and maintain a firm contact.

■ 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.
