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, 1995, 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. Precautions and safety measures
1.1.1. Preliminary
- This device can be used for measurements on category III installations, for voltages never exceeding 600 V (AC or DC) relative to the earth.
- Definition of overvoltage categories (see. publication IEC 664-1):
CAT I : The CAT I circuits are protected by safety measures limiting transient overvoltages to appropriate low level. Example : protected electronic circuits
CAT II : The CAT II circuits are power supply circuits of appliances or portable equipment with transient overvoltages of an average level. Example : appliances and portable equipment
CAT III : The CAT III circuits are power supply circuits of power equipment with high transient overvoltages. Example : fixed installation or industrial equipment
CAT IV : The CAT IV circuits may comprise very high transient overvoltages. Example : primary supply level
* When using this multimeter, the user must observe all normal safety rules concerning:
- protection against the dangers of electric current.
- protection of the multimeter against misuse.
* For your own safety, only use the test probes supplied with the instrument and, check, before use, that they are in good working condition.
1.1.2. During use
* Test equipment risk assessment : Users of this equipment and/or their employers are reminded that Health and Safety Legislation requires them to carry out a valid risk assessment of all electrical work so as to identify potential sources of electrical danger and risk of electrical injury such as from inadvertent short circuits. Where the assessment show that the risk is significant then the use of fused test leads constructed in accordance with the HSE guidance note GS38 "Electrical Test Equipment for use by Electricians" should be used.
* Never exceed the protection limit values indicated in the specifications for each type of measurement.
* 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.
* In TV repair work, or when carrying out measurements on power switching circuits, remember that high amplitude voltage pulses at the test points can damage the multimeter. Use of a TV filter will attenuate any such pulses.
* Never perform resistance or continuity measurements on live circuits.
1.1.3. Symbols
Symbols used in this manual and on the instrument :
CAUTION : Refer to the instruction manual.
Incorrect use may result in damage to the device or its components.
DANGER : High voltage, risk of electric shock.
Earth
1.1.4. Instructions
* Before opening up the instrument, always disconnect from all sources of electric current and make sure you are not charged with static electricity, which may destroy internal components.
* Fuses must be replaced with fuses of the same rating and type.
* Any adjustment, maintenance or repair work carried out on the multimeter while it is live should be carried out only by appropriately qualified personnel, after having taken into account the instructions in this present manual.
A "qualified person" is someone who is familiar with the installation, construction and operation of the equipment and the hazards involved. He is trained and authorized to energize and de-energize circuits and equipment in accordance with established practices.
* When the instrument is opened up, remember that some internal capacitors can retain a dangerous potential even after the instrument is switched off.
* If any faults or abnormalities are observed, take the instrument out of service and ensure that it cannot be used until it has been checked out.
* It is recommended to remove the battery from the instrument if not used.
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.
* Two HBC fuses provide protection up to 600 V during measurements of intensity type.
* An IP protection rating of 40.
* Maximum protection between mA and 10 A input terminals : 500 V.
1.3. Safety mechanisms
* The battery unit cannot be accessed without first disconnecting the measuring leads.
* When measuring voltages above 24 V, the sign blinks ⚡ on the display.
* When measuring voltages above 10 A, the sign blinks △ on the display and an intermittent audible signal warns the user.
* If the maximum range is repeatedly exceeded, an intermittent audible signal warns the user in volt (DC and AC+DC) and current (DC and AC+DC) functions.

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. It can also be used to access secondary functions associated with the selector switch positions : mode AC+DC.
The flowcharts below define these various functions.

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).
Automatic shutdown of the instrument is disabled in order to avoid interrupting the peak measurements (Pk +/-).
4.3. MEM / AUTO MEM key
Short press (MEM) : Fixes the display on the current value. A second short press returns the multimeter to normal mode. The “MEM” sign appears on the display.
The MEM mode is available on all measurements.
Long press (AUTO MEM) : Accesses or quits the "autostore" mode.
The "MEM" sign blinking on the display.
Affected ranges : VLOWZ, VAC+DC, VDC, ADPDC, ADPAC+DC
Autostore
Set the probes on the point to be measured. An audio signal indicates whether the measurement is stable. When you remove the probes, a second audible signal indicates that this stable value displayed has been stored.
The bargraph remains active during the "autostore" and display "MEM "mode.
Pressing this key when switching on the instrument enables the selection of a rejection of 50 or 60 Hz. The selection is reversed from the last configuration. It is displayed for 2 secs. and remains backed up in non-volatile memory.
4.4.
key
Activates/desactivates back lighting of the display unit. It automatically goes off after ≈ 60 seconds.
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:
