USE 2.1 First use Fit the battery shipped with the instrument as follows: 1. Using a screw driver, unscrew the four screws on the cover (item 1) located at the rear of the unit; 2. Place the battery in its housing (item 2) while respecting the polarity; 3. Screw the cover back on. 1 2 Figure 5: access to the battery 2.
2.4 The stand There are two stand positions, one for suspending the multimeter (position 1) and the other providing a stand (position 2). To change the stand position, proceed as follows: Position 1: fit the stand studs into the upper holes located on the rear of the unit: Position 2: fit the stand studs into the lower holes located on the rear of the unit: 3. FUNCTIONS 3.1 Switch functions To access the , , , , , or , position. Every position (except OFF) is confirmed by a beep.
3.1.2 Voltage measurement The instrument measures the following types of voltages: DC voltage with high impedance (DC); AC voltage with high impedance (AC); AC voltage with low impedance (VLowZ) In all cases "O.L " displays in excess of 1050 V and a beep sounds when the measurement exceeds 600 V. Volt VLowZ : This position is designed for measurements on electrical installations. The input impedance < 1 MΩ is used to avoid measuring "phantom" voltages caused by coupling between the lines.
3.1.4 Resistance measurement To measure the resistance, proceed as follows: 1. Set the switch to ; 2. Connect the black lead to the COM terminal and the red lead to "+"; 3. Place the test probes on the terminals of the component; Remark: all resistance measurements must be performed with the power off. 4. Read the measurement indicated on the display. 5. "O.L" is displayed if the circuit is open. 3.1.5 Audible continuity measurement For audible continuity measurement, proceed as follows: 1.
3.1.6 Diode test To measure and check a semiconductor junction, proceed as follows: 1. Set the switch to 2. Press twice on ; . The symbol is displayed; 3. Connect the black lead to the COM terminal and the red lead to "+"; 4. Place the test probes on the terminals of the component; 5. Read the junction threshold voltage measurement indicated on the display. 6. "O.L" is displayed if the circuit is open. 3.1.7 Capacitance measurement To measure the capacitance, proceed as follows: 1.
3.1.8 Temperature measurement To measure the temperature, proceed as follows: 1. Set the switch to 2. Press ; to select the unit and scale of the temperature (° C or ° F). Remark: the default measurement unit displayed is ° C. 3. Connect the temperature sensor to the COM and "+" terminals respecting the poles; 4. Read the measurement indicated on the display. 5. "O.L" is displayed the thermocouple is cut. NB: For greater accuracy, avoid subjecting the instrument to sudden temperature changes. 3.1.
Detection of fuse tripping - or meltdown: If the fuse has melted, the circuit between COM and the 10 A socket is cut. The display shows zero. 1. Set the switch to Ω. 2. Connect the V socket to the 10 A socket (see above); leave the "COM" socket free. 3. The display should show a result < 2 Ω, otherwise replace the fuse. 3.2 Key functions The functions: , , , can be accessed by pressing a key repeatedly, using short or long presses. The long-press function is shown by the pictogram under the key.
3.2.2 Key This key is used to manually select a measurement range or to activate the screen backlighting. The range defines the maximum range for measurements performed with the instrument. Remark: the Auto Range mode is activated by default. In normal mode Type of press short Resulting action on manually changes the measurement scale (extent and resolution). Example: In , mode, the screen displays: 59.00 V, range Auto When pressed the first time, the screen displays: 59.
In mode Type of press Resulting action short exit from on 15 mode.
3.2.3 Key This key displays the MAX, MIN modes. Max and Min fill in the highest and lowest values of the measurement. In normal mode Type of press Resulting action short enters the MAX/MIN mode. Note that in permanent operation. is displayed on to select the quantities for MAX or MIN Reminder: the MAX quantity is displayed by default. Example: display screen V / MAX. long (> 2 sec) quits the mode. on Remark: Auto power off is automatically activated. In + mode : refer to §.
3.2.4 Key This key is used to memorise the measurements and quantities or to deactivate the automatic power-off function on the instrument. In normal mode Type of press Resulting action short memorises a measurement status at a given moment and then makes it possible to view them successively on the display. on If activated, the Min Max acquisition continues as a background task. The bargraph continues to operate normally (even in Hold).
In mode Type of press Resulting action short on freezes the display of each MAX, MIN quantity displayed. MAX, MIN,acquisition continues in the background. This is indicated by blinking of the MAX, MIN symbols. If you press a second time, you quit the 18 mode.
