Chapter II 1. GENERAL INSTRUCTIONS You are the new owner of a 5000 ct portable digital multimeter and we thank you for your choice. This instrument complies with the specification set out in the IEC 61010-1 + A1 + A2, 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. The contents of this manual must not be reproduced in any form whatsoever without our consent. 1.1.
Chapter II ∗ When the multimeter is linked to measurement circuits, do not touch unused terminals. ∗ When the range of the value to be measured is unknown, check that the range initially set on the multimeter is the highest possible or, wherever possible, choose the autoranging mode. ∗ Before changing functions, disconnect the test leads from the circuit under test.
Chapter II 1.2. Protection mechanisms This instrument is fitted with various protection mechanisms : ∗ Varistor protection for limiting transients of over 1100 V at the VΩ terminal, particularly 6 kV pulse streams as defined by the French standard IEEE 587. ∗ A PTC (positive temperature coefficient) resistor protects against permanent overvoltages of up to 600 V during resistance, capacitance, continuity and diode test measurements. This protection is reset automatically after overload.
Chapter II 2. DESCRIPTION This compact multimeter is a self-contained with an appropriate mechanical construction, enables hand-held version, with a protective elastomer case. It is designed for a high degree of user safety, maximum protection and unrivalled performance. 2.1. Selector switch This multimeter is a standalone, hand-held professional measuring instrument, capable of measuring the following quantities (accessed by the twelve-position rotary selector switch): ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ 2.2.
Chapter II 3. GETTING STARTED 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 VLOW Z, VAC+DC, VDC, ADPDC (ADPAC+DC), Hz, 500 mADC (500 mAAC+DC) 10 ADC (10 AAC+DC) Input terminal , Ω, , VΩ 500 mA 10 A RS232 lead : Connect the RS232 optical interface (optional kit) to the top of the multimeter casing and the DB9F plug to PC (COM port).
Chapter II 3.5.2. Battery self-test When the BAT indication appears on the display, the instrument still has approximately 12 hours of operation, but specifications can no longer be guaranteed. Replace the battery. 3.5.3. Replacing the battery or fuses * Caution ! Disconnect test leads from any circuit under test, turn the meter off and remove test leads from the input terminals . Use the following procedure: 1 - Disconnect test leads from any input terminals.
Chapter II 4. FUNCTION DESCRIPTION 4.1. RANGE / AC+DC key The RANGE key is operative in following positions of the selector switch : VLOW Z, VAC+DC, VDC, Ω, , Hz. This key makes it possible : • In AUTO (Autoranging) mode to switch to MANUAL mode (short press). • In MANUAL mode, to select the next range (short press) or return to AUTO mode (long press), the AUTO sign appears on the display. This can be used to switch on the multimeter again after an automatic shutdown.
Chapter II 4.1.3. 10 ADC / 10 AAC+DC Position 10 ADC DC current measurement (Range 10 ADC) AC+DC key 10 AAC+DC AC+DC current measurement (TRMS) (Range 10 AAC+DC) The AC+DC sign appears on the display. AC+DC key 4.2. +/- Peak key The fast positive or negative peak measurement functions (> 1 msec.) can be accessed by repeatedly pressing this key in the VDC, ADPDC, mADC and 10 ADC functions. This key also desactivates the auto power-off, if it is pressed when switching on (“P-OFF” is displayed).
Chapter II 5. SOFTWARE KIT (optional) Connection of the kit and installation of the SX-DMM software : With the software kit option, the multimeter can interface directly with a computer or PC: 1. Connect the optical plug at the top of the shockproof sheath. A mechanical fail-safe device is provided on the left-hand side to prevent connection the wrong way round. 2. Plug the connector into one of the PC's "COM" ports. 3.
Chapter II 6. TECHNICAL SPECIFICATIONS 6.1. General Only the values assigned tolerances or given limits are guaranteed values. Values without tolerances are given for information only, without guarantee (standard NFC 42670). The measurement errors must be considered in an environment of reference temperature (refer to § 6.2.11). It is essential that all measuring instruments are regularly calibrated. 6.2. Characteristics Accuracy is ± [% reading (R) + number of digits (D)].
