CHAPTER 2
PRODUCT FEATURES
2.1 Description
These portable megohmmeters function with batteries. They can be used
to check insulation and voltages, and to measure resistances. The
Model 1039 can also be used for:
• measurement of the capacitance of a telephone line
• current measurement
• measurement of the pure alternating component of a DC
voltage
These megohmmeters help to ensure the safety of electrical and
telephone installations. The acquisition, processing and display of the
measurements are managed by a microprocessor. They o󰀨er a wide
range of advantages such as:
• automatic detection of the presence of a dangerous voltage
on the terminals in MΩ ranges (all insulation measurement
blocked if V > 25 V)
• protection of the instrument against external voltage surges
• operator safety by means of automatic discharge of the high
voltage on the equipment tested
• display of the di󰀨erence compared to a measurement value
in memory
• measurement of the length of a telephone line according to
its capacitance per km unit length (1039)
• automatic shutdown of the instrument to save the batteries
and indication of the battery charge
• fuse testing by periodic checks during current measurement
(1039)
• a large backlit LCD screen with a wide range of indicators
making it very easy for the user to read

2.5 Button Functions
2.5.1 Yellow Push Button
The yellow button is used to initiate the test voltage when measuring
insulation resistance. In any function setting (except OFF), the
megohmmeter is in the voltage mode and works as a voltmeter to detect
if any voltage is present on the tested sample. If a voltage greater than
25 V is detected, the yellow test button is disabled and insulation testing
is not possible.
2.5.2 ALARM Button
The ALARM button can be used to activate/deactivate the alarm
thresholds during insulation and resistance measurements.
It is also used with the ► and ▲ selection cursor buttons to adjust the
alarm set points.
2.5.3 Cursor Button
When programming the alarm setpoints, the ► cursor button makes the
following symbols ash as follows:
- the measurement unit (if applicable),
- the thousands digit,
- the hundreds digit,
- the tens digit,
- the units digit,
- the decimal point,
- the alarm trigger (above or below the setting)
- and it then returns to the measurement units.
The capacitance per unit length in nF/km (with the button on the
1039). By pressing the ► button, you can make the following elements
ash successively:
- the tens digit,
- the units digit,
- and it then returns to the tens digit.

Digital Analog Megohmmeter Models 1035/1039 14
2.5.4 Scroll Cursor Button
When programming the alarm setpoints, the ▲ button is used to scroll
through the possible values for each parameter, which ashes:
- MΩor GΩfor insulation, kΩor Ωfor resistance, for the
measurement units,
- 1,2, 3 or _ for the thousands digit,
- 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 for the hundreds, tens and units,
- “-.- - -” or “- -.- -” or “- - -.-” or “- - - -” for the decimal separator,
- > or < for above or below threshold trigger.
- When programming the capacitance per unit length in nF/km, the
▲ button can be used to change the values of the ashing digits
to 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9.
2.5.5 Backlight Button
1035 and 1039: When this button is pressed, the backlighting of the
display comes on. It will be turned o󰀨 automatically one minute later.
When it is lit, you can turn the backlighting o󰀨 by pressing this button
again.
1039: When the switch is on 4000 nF, a long press on this button
enables you to program the unit length value (see § 2.7.8).
2.5.6 REL Button
A long press on this button enables you to memorize a value. The
measurements that follow will be the positive or negative deviation
compared with the value memorized (does not function for voltage on the
MΩpositions).

15 Digital Analog Megohmmeter Models 1035/1039
2.6 Measurement Functions
2.6.1 AC/DC Voltage Measurement - Safety Check
As soon as the switch is set to one of the MΩpositions, the instrument
measures the voltage between its + and - terminals. The value of this
voltage is displayed (0 to 600 VAC/DC max).
If the voltage present is less than 25 V, the insulation can be
tested, but the lower the test voltage the greater the possibility of
error.
If the voltage is greater than 25 V, and >25 V are displayed.
Pressing the yellow button will only cause the buzzer to turn on
and the symbol to ash until the button is released.
These warnings only end if the voltage falls below 25 V (disconnection of
the leads or removal of the voltage) or if the yellow button is released or,
naturally, if you turn o󰀨 the instrument by returning the switch to the OFF
position.
WARNING: If the voltage detected is above 600 V (outside mea-
surement range), OL will appear on the digital display.
2.6.2 Insulation Resistance Testing
If there is not a dangerous voltage (see above), the user can then
measure the insulation by pressing the yellow button. The high voltage
is then generated between the terminals (marked + and -). The value
of the measurement is shown on the logarithmic scale of the bargraph
and on the digital display, with the corresponding MΩor GΩsymbol. As
soon as the yellow button is released, the instrument returns to voltage
measurement mode.
WARNING: If the voltage generated may be dangerous, is
displayed.

Digital Analog Megohmmeter Models 1035/1039 16
The instrument indicates if the value measured is outside its
measurement range. If the measured insulation resistance is greater
than 400MΩ(1039), 2 or 20 GΩ (1035), the OL symbol is displayed on
the digital display instead of a value. When the measurement is greater
than 1.1 GΩ, the ► symbol lights up on the right-hand side of the
bargraph. Similarly the digital measurement display indicates “- - -” if the
insulation resistance is less than:
Model 1039: 10 kΩ at 50 V; 20 kΩat 100 V
Model 1035: 10 kΩ at 50 V; 20 kΩ at 100 V; 50 kΩ at 250 V;
100 kΩat 500 V
When the measurement is less than 70 kΩ, only the ◄ symbol lights up
on the left-hand side of the bargraph.
To measure high insulation values, you are advised to use the “G” guard
terminal to remove the inuence of supercial leak currents and “hand
capacitance”.
2.6.3 Resistance
Resistance measurement corresponds to the 40 kΩposition of the switch
on the 1039 and the 400 kΩposition on the 1035. The measurement is
indicated on the digital measurement display, accompanied by the Ωor
kΩsymbol if necessary. The instrument indicates if the value measured
is outside its measurement range. If the resistance is greater than 40 kΩ
or 400 kΩ, depending on the instrument, the OL symbol is displayed on
the digital measurement display. A programmed threshold may trigger
an alarm (see pg 18).

17 Digital Analog Megohmmeter Models 1035/1039
2.6.4 Capacitance (1039)
Capacitance measurement corresponds to the 4000 nF position of the
switch. The measurement is shown on the display accompanied by the nF
symbol. The length of the telephone line measured is indicated in km on
the digital threshold display, according to the programmed capacitance
per unit length.
If the leads are set up in a short circuit, the instrument indications
OL on the digital measurement display and the distance is - - - km.
If the capacitance measurement is greater than 4000 nF, the
OL symbol is displayed on the digital measurement display.
If the distance measurement is greater than 80 km, the OL
symbol is displayed on the digital measurement display.
If the leads are not connected, the digital measurement display
indicates 0.00.

Digital Analog Megohmmeter Models 1035/1039 18
2.6.5 AC/DC Current (1039)
Current measurement corresponds to the 400 mA position of the switch.
The measurement is shown on the display accompanied by the mA
symbol. The fuse is checked periodically.
If the current measurement is greater than 400 mAAC/DC, the
OL symbol is displayed on the display. The MN211 Current Probe
may be used to extend the measurement range to 200AAC.
2.6.6 AC Voltage (1039)
AC voltage measurement corresponds to the V~ position of the switch. The
measurement is shown on the display accompanied by the VAC symbol. In
this function, the DC component is not measured.
If the voltage measurement is greater than 400 VAC, the OL
symbol is displayed on the digital measurement display.
2.7 Special Functions
2.7.1 Battery Life Indication
When you move the switch from the OFF position to one of the function
positions, the battery voltage is applied to the circuit. All the display seg-
ments light up at the same time for 1 second. Then all the segments go out
(for 2 seconds) except the and the ◄ and ► symbols which delimit
the size of the bargraph.
The bargraph indicates the battery charge life and the digital measure-
ment display indicates the charge life available (0.00 to 1.00 = 0 to 100 %).
The instrument can be turned o󰀨 at any time by turning the rotary switch
to OFF.
2.7.2 Auto-O󰀨
After 5 minutes without any activity, the instrument automatically shuts o󰀨.
To start up the instrument again, press any one of the buttons, turn the
switch, or press the yellow test button on the remote control test probe.

19 Digital Analog Megohmmeter Models 1035/1039
DISABLING/ENABLING THE AUTO-OFF
• To disable the Auto-O󰀨, keep the button pressed down when
turning ON the instrument. The symbol is then displayed, indi-
cating that the Auto-O󰀨 function has been disabled.
• To enable the Auto-o󰀨 function, turn the instrument OFF and then
turn it back ON again. Auto-O󰀨 is the default mode.
2.7.3 Battery Auto Test
The battery supply voltage is measured automatically every second. The
battery voltage range for correct operation is 7 V to 10 V. There are four
possible cases:
• The voltage is correct: Nothing is displayed.
• The voltage is < 7.1 V: the symbol ashes. Remaining bat-
tery life is limited.
• The voltage is < 6.9 V: the symbol remains lit. Measurement
accuracy is no longer assured. Replace the batteries.
• The voltage is close to 6.7 V: the digital display indicates BAT and
then, after 5 seconds, the shutdown buzzer sounds, and the Auto
OFF function is activated. The instrument shuts down.
2.7.4 Fuse (1039)
The fuse is tested automatically when the instrument is started up and
then checked periodically during current measurement.
2.7.5 Buzzer
DISABLING/ENABLING THE BUZZER
Keep the ALARM button pressed down when you start up the instrument
by turning the switch. The symbol is no longer displayed.
To reactivate the buzzer, switch the instrument OFF and then back ON
again.

Digital Analog Megohmmeter Models 1035/1039 20
THE DIFFERENT SOUNDS
When the symbol is displayed, the buzzer is active. It gives out di󰀨erent
sounds, depending on the operation or warning.
• Short buzz (65 ms at 2 kHz):
- push on a button
- auto OFF
• Continuous buzz (at 2 kHz):
- measurement is lower than the minimum setpoint
- measurement is higher than the maximum setpoint
• Short, higher buzz (65ms at 4 kHz):
- when a disabled (inactive) button is pressed
(except the yellow test button)
• Repeated high buzzes (at 4 kHz):
- the detected voltage (safety check) at the sample is
greater than 25 V and the yellow button is pushed
2.7.6 Alarm Setpoints
Alarm setpoints can only be programmed for insulation and resistance
measurement. The setpoints can be upper or lower thresholds. They can
be active or inactive and will be stored in the memory even after the
instrument has been turned o󰀨.
PROGRAMMING OF THE ALARM SETPOINTS
To program the setpoint press the ALARM button until the ALARM symbol
is displayed and beeps a second time (the setpoint unit will blink, e.g. MΩ).
The value of the setpoint corresponding to the selected range is indicated
on the small digital display.
If no value was previously programmed, the display indicates a default
setpoints:
• On the 1039: > 0.050 MΩfor the MΩ- 50 V position
> 0.100 MΩfor the MΩ- 100 V position
< 20.00 kΩfor the 40 kΩposition
• On the 1035: > 0.05 MΩfor the MΩ- 50 V position
