1.1. DELIVERY CONDITION Delivered in blister pack with: two 1.5V batteries (AAA or LR3), one set of two leads each terminated by a probe tip, one type K thermocouple, one multilingual safety data sheet, one user’s manual in ve languages.

1.2. INSERTING THE BATTERIES

Lift the prop. Using a small cross-headed screwdriver, unscrew the screws of the battery compartment cover. Withdraw the battery compartment cover. Insert the two batteries provided (AAA or LR3 1.5V alkaline batteries). Put the battery compartment cover back in place. Make sure that it is completely and correctly closed, then screw the screws back in. 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).16 AUTO %ºC kMΩHz mAVF

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 rm contact. The voltage is displayed. At the end of the measurement, disconnect the + terminal rst, 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, rst 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 µA, 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 rm 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 Ω . 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 rm 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 rm contact.18 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 rm 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 conrm 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.19
