- "RANGE" key
Your multi meter has a range change function that is normally auto matic but can be made
manual. After the quantity to be measured is chosen manually ("SEL" key), the default
mode is automatic range change: the "AUTO" message is then displayed.
Briefly press the "RANGE" key to change to manual mode: the "AUTO" message is
then replaced by "MANU".
Successive brief presses are used to reach the desired range.
Hold the "RANGE" key down for 2 seconds to return to the automatic range change
mode: the "MANU" message reverts to "AUTO".
"HOLD" key
In the "HOLD" mode, the device freezes the display of the last value measured.
Pressing the "HOLD" key briefly during a measurement freezes the display: the
message is then displayed.
A second brief press on the "HOLD" key is used to return to the normal
measured value display refresh mode: the message disappears from the
display unit.
"MAX MIN" key
The device records the maximum and minimum values of the measurements made. The
automatic range change does not change the range when this mode is entered; if the
maximum values exceed the display range (indicated by the "OL" message), the
appropriate higher range must be chosen manually before reactivating the "MAX MIN"
mo de .
Successive brief presses on the "MAX MIN" key produce, in order, the following actions:
1st press: the device records and displays the maximum value
measured. The "AUTO" message is replaced by "MANU" and the "MAX" message is
displayed.
2nd press: the device records and displays the minimum value measured; the
"MAX" message is replaced by "MIN".
3rd press: the device records the maximum and minimum values measured
simultaneously; it is the value currently measured that is displayed; the "MAX" and
"MIN" messages blink simultaneously on the display unit.
Additional presses serve to display the values recorded one by one by
reproducing the actions of the previous successive presses.
Press the "MAX MIN" key for two seconds to exit from the mode: the "MANU", "MAX",
and "MIN" messages are replaced by "AUTO", indicating that the device once again
changes range automatically.
"Hz" (Hertz) key
When the switch is set to "VHz", a brief press on the "Hz" key displays the frequency of
the voltage being measured.
A 2nd press restores the display of the voltage being measured.

1.4 The leads and test probes
The multimeter is equipped with 2 leads (1 red and 1 black), each terminated by a test
probe of the same colour. The leads and test probes are not detachable (they are
permanently connected) and, whe n not in use, can be stowed in the compartments
provided for them on the right side of the device.
The tips of the test probes (once taken out of their compartments by pressing on them
with a finger), allow voltage, resistance, continuity, diode test, and capacitance
measurements.
The test probes have physical guards that show the operator where the hand grip part
ends, beyond which the fingers must not be placed.

2. USE
2.1 Commissioning
Place the batteries supplied with the device as follows:
1. Using a cross-headed screwdriver, unscrew the screw of the compartment cover on
the back of the housing and open the cover.
2. Place the 2 batteries in their compartment, with the correct polarities.
3. Close the cover and screw it back to the housing.
2.2 Starting up and check of operation
We recommend performing this procedure at the time of commissioning and, if the device
is used only occasionally, each time it is used.
Hold the "HOLD" key down and switch the instrument on by turning t he switch from
"OFF" to "Ω".
Keep the "HOLD" key pressed and check that the various symbols and segments
are correctly displayed (the 1st digit on the left may be a "6" or an "8").
Releasing the "HOLD" key restores the normal display for the function chosen.
If the device is set to the resistance measurement function ("Ω"), check that the
display indicates "A.P.O" (for auto power off), "SCAN" (for automatic search for the
quantity to be measured), dashes "---" (to indicate search in progress).
Withdraw the two leads from their compartment and establish a good contact between
the metallic parts of the two test probes; the value measured and displayed must
change from "---" to "0.0Ω" accompanied by the message " " (the value displayed
may not be exactly zero, but must remain very close to zero).
The instrument is operational when the various states described above have been
checked and are correct. The rotary switch can then be set to the desired function or
to "OFF" to switch the instrument off.
2.3 Deactivating Auto Power Off
In order to extend the life of the batteries, the device switches itself off automatically
approximately 10 minutes after it is switched on if no key or change of function has been
activated.
- 6 -

The device warns that it is about to switch off by emitting 3 series of 2 audible beeps
and, if no action is taken, then emits a long beep and switches itself off.
When the multimeter has switched itself off automatically, it can be reactivated by
any action on a key or on the rotary switch.
Automatic switching off can be deactivated by holding dow n the "Hz", "MAX MIN", or
"R-H" key while switching on.
To eliminate the slight residual drai n of the batte ries in t he s leep mode, it is always
best to switch the device "OFF".
2.4 DC voltage measurement (V )
For optimum safety, measurements of voltages between 300V and 600V must be
made only on category III installations or on circuits of which the possible overvoltage
levels are known to be less than those of category III.
The instrument has 4 measurement ranges: 600mV, 6.0V, 60V, 600V.
The 600mV range can be used only in the manual range change mode, by repeated
presses on the "RANGE" key. The other ranges can be used in either the manual or the
automatic range change mode.
Withdraw the test probes and leads from their compartment.
Switch the instrument on in the "V" setting.
Apply the metallic part of the black test probe on the (assumed) ne gative part of the
circuit to be tested.
Apply the metallic part of the red test probe on the (assumed) positive part of the
circuit to be tested.
Read the measurement result (after stabilization).
Display of the "-" sign in front of the numerical value indicates that the value measured is
negative (the test probes are reversed with respect to the polarity of the voltage)
2.5 AC voltage measurement (V )
For optimum safety, measurements of voltages between 300V and 600V must be
made only on category III installations or on circuits of which the possible overvoltage
levels are known to be less than those of category III.
The instrument has 4 measurement ranges: 600mV, 6,0V, 60V, 600V.
The 600mV range can be used only in the manual range change mode, by repeated
presses on the "RANGE" key. The other ranges can be used in either the manual or the
automatic range change mode.
Withdraw the test probes and leads from their compartment.
Switch the instrument on in the "V" setting.
Apply the metallic part of the black test probe on the part of the circuit to be tested
(assumed) closest to the earth potential.
Apply the metallic part of the red test probe on the part of the circuit to be tested
(assumed) farthest from the earth potential.
In the "SCAN" mode, if the voltage to be measured is greater than 0.5V, the
multimeter automatically determines if an AC or DC measurement must be made.
If necessary, press the "SEL" key briefly to force an AC voltage measurement (display
of the " " symbol instead of " ")
Read the measurement result (after stabilization).
- 7 -
2.6 Frequency measurement (Hz)
For optimum safety, measurements of voltages between 300V and 600V must be
made only on category III installations or on circuits of which the possible overvoltage
levels are known to be less than those of category III.
The instrument has 3 measurement ranges: 600,0Hz, 6,000kHz and 60,00kHz.
Measurement of the frequency of the voltage measured: start the AC voltage
measurement method, then press the "Hz" key (display of the "Hz" symbol instead
of "V").
Read the measurement result after stabilization.
2.7 Resistance measurement (Ω)
Resistance, continuity, diode test, and capacitance measurements must be made
only on circuits completely disconnected from any power supply, and after any capacitors
have been discharged.
The instrument has 6 measurement ranges: 600,0Ω, 6,000kΩ, 60,00kΩ, 600,0kΩ,
6,000 MΩ and 60,00 MΩ. All of the ranges can be used with either automatic or manual
range change.
Withdraw the test probes and leads from their compartment.
Switch the instrument on and set to " ".
Apply the metallic tips of the test probes to the terminals of the resistance or of the
circuit to be tested.
In the "SCAN" mode, the multimeter automatically determines the nature of the
quantity to be measured.
If necessary, press the "SEL" key briefly to change to the desired measurement
mo de .
Read the measurement result (after stabilization).
NB: Touching the elements or circuit during the measurement may lead to erroneous
results. For resistance measurements on nonlinear circuits, it may be necessary to select
the measurement mode and the range to be used manually.
2.8 Continuity measurement (Ω)
Resistance, continuity, diode test, and capacitance measurements must be made
only on circuits completely disconnected from any power supply and after any capacitors
have been discharged.
The instrument indicates continuity by emitting a steady sound when t he resistance
measured is less than 30Ω. The value displayed is the value measured in ohms.
Withdraw the test probes and leads from their compartment.
Switch the instrument on and set to " ".
Apply the metallic tips of the test probes to the terminals of the resistance or of the
circuit to be tested.
In the "SCAN" mode, the multimeter can automatically determine and select the
continuity mode when the resistance measured remains low; otherwise press
the "SEL" key briefly until the continuity symbol " " appears
Read (if necessary) the measurement result (after stabilization).
- 8 -
2.9 Diode measurement (Ω)
Resistance, continuity, diode test, and capacitance measurements must be made
only on circuits completely disconnected from any power supply, and after any capacitors
have been discharged.
The instrument indicates the voltage across the terminals of the semiconducting junction.
Withdraw the test probes and leads from their compartment.
Switch the instrument on and set to " ".
Apply the metallic tips of the test probes to the terminals of the diode or circuit to
be tested.
In the "SCAN" mode, the multimeter can automatically determine and select the
diode test mode when the voltage measured is less than approximately 0.8V,
otherwise, press the "SEL" key briefly until the diode test symbol " " appears.
The test probes must be applied to the terminals of the diode or junction to be tested
according to the following polarities.
1) forward direction (conducting): apply the black probe to the cathode and the red
probe to the anode. Read the measurement result (after stabilization), see figure A
(the threshold voltage of a silicon diode is between 0.5V and 0.7V; it is between 0.2
and 0.3V for a germanium diode. High-voltage diodes, some Zener diodes, and LEDs
cannot be tested by this method).
2) reverse direction (non-conducting): apply the black probe to the anode and the red
probe to the cathode. Read the measurement result (after stabilization), see figure B
(a diode or junction in good condition causes the display of "OL").
With some types of diode, a measured value outside the stated voltage ranges
does not necessarily mean that the diode or junction is defective.
