Chapter II GENERAL INSTRUCTIONS You have just acquired a portable digital multimeter and we thank you for your confidence. This instrument complies with the specification of EN publication 61010-1, concerning safety requirements for electronic measuring apparatus. To get the best service from this instrument, read carefully this user's manual and respect the detailed safety precautions.
Chapter II ∗ When performing current measurements, never change of range, do not connect or disconnect leads without first isolating the current. If you do, there is a risk of generating surge currents which can blow the fuses or damage the instrument. ∗...
Chapter II 1.3. Safety devices ∗ The battery unit and fuses cannot be accessed without first disconnecting the measuring leads. ∗ When measuring voltages above 24 V, the symbol blinks on the display. ∗ If the maximum range is repeatedly exceeded, an intermittent audible signal indicates the risk of electric shock.
Chapter II DESCRIPTION This multimeter is one of the ASYC II (Advanced SafetY Concept, third generation) family, designed for a high degree of user safety, maximum protection and a hitherto unrivalled performance. 2.1. Selector switch It is a standalone, handheld professional measuring instrument, capable of measuring the following quantities (accessed by the ten-position rotary selector switch) : ∗...
Chapter II COMMISSIONING 3.1. Connecting the test leads Connect the black lead to the COM socket (for all measurements). Depending on the position of the selector switch, connect the red lead as follows: Rotary selector switch position Input terminal , Ω, , °C , mV VΩ...
Chapter II 3.5. Multimeter maintenance 3.5.1. Fuse self-test When fuse F1 (0.63 A) or F2 (11 A) is blown, the display shows “FUSE.1” or “FUSE.2”, accordingly. If both fuses are blown, the display shows “FUSES”. Replace the fuse or fuses concerned. μ...
Chapter II FUNCTIONAL DESCRIPTION 4.1. SEL/ON key This can be used to switch on the multimeter again after an automatic shutdown. It can also be used to access secondary functions associated with the selector switch positions. The flowcharts below define these various functions. 4.1.1.

Chapter II 4.2. RANGE key • AUTO mode to switch to MANUAL mode (short press). • MANUAL mode, to select the next range (short press) or return to AUTO mode (long press). Measurements concerned : voltages (except 500 mV range), capacitance, resistance, current (except 10 A range).
Chapter II 4.7. SURV key If you press this key (long press), you access the surveillance mode (or coming out), in which minimum (MIN), maximum (MAX) and sliding average (AVG) values of the current measurement are stored. You can look up each of these values by repeatedly pressing the same key (short press). The symbols MIN, MAX or AVG flicker with the selected value.
Chapter II TECHNICAL SPECIFICATIONS Only those values assigned tolerances or limits are guaranteed values. Values without tolerances are given for information only (French standard NF C 42-670). The technical specifications are guaranteed only after 30 min warm-up period. Except special indication, they are valid from 5 to 100 % of the range of measurement.
Chapter II Number of counts : 50 000 (or 5 000, refer to §. 3.4.) Range selection : automatic or manual for the 500 µA, 5 mA, 50 mA, 500 mA ranges Additional error according to crest factor : 0.2 % for a crest factor of 2 to 3 0.5 % for a crest factor of 3 to 6 (Specification given full scale for a squarewave signal pulse 200 µs wide) Additional error in I...
Chapter II 5.7. Diode threshold voltage measurement Measurable voltages : 0 to 2 V Measurement current : 1 mA typical Resolution : 1 mV Protection : 600 V , can be reset automatically 5.8. Frequencies Selector switch setting : , mV, V , mA, 10 A Measurement range : 0.62 Hz to 500 kHz...
