Insulation Resistance.
Capacitance.
Leakage Current.
Advantages:
Automatic voltage detection in all functions, before or during the
measurement, which inhibits or stops the measurement.
Automatic detection of external AC or DC voltages on the terminals.
Threshold programming in each function to trigger audible alarms.
Timed control of measurement duration.
Fuse protection with defective fuse detection and indication.
Automatic discharge of residual high voltage on the tested device.
Battery level indicator.
Large, easy-to-read, and back-lit LCD.
128 kB memory, real-time clock, and USB serial port.
Control and programming of the instrument from a PC (with DataView®
software) for download, report, and printing.

Printing measurement data is completed through DataView® software.
Indicates the value of:
Insulation measurement (resistance, DAR and PI, DD, capacitance).
Indicates:
Voltage measured or applied by the instrument.
Elapsed time or the output voltage, during insulation measurement.
After recording a set of data (5060), the small display also indicates the time and
date in MR (memory recall) mode, and the memory address with the OBJ : TEST
number.
Active during insulation measurement (0.1 M to 1 T ).
Indicates the battery charge at start-up.
Indicates free memory space. One segment represents approximately 100
groups of saved values with each group holding approximately 50 recordings
(1 OBJ and 1 TEST).

Memory address (5060) - indicates the memory operation.
OBJ:TEST: Memory address (5060) - the number is displayed on the small
digital display.
COM: Flashes on the screen when data is transmitted to the serial interface
(5060) or remains permanently displayed if there is a problem during transfer.
Indicates the mode chosen before insulation measurement or the
results of these measurements.
Indicates external voltage present, symbol is activated after pressing
AC DC.
Activation of “time-controlled test” mode or clock adjustment when in
SET-UP (5060).
(Yellow button) Selects the second (bottom) function of a button.
Flashes if the battery voltage is low to indicate that the battery should
be recharged (see § 8.1). The voltage is displayed on the small display
for 2 seconds when the instrument is turned on. The main display
indicates “bat” when the test is carried on.
Warning buzzer is activated.
SMOOTH: Smooths the insulation measurements displayed.
REMOTE: Remote control via an interface (5060). In this mode, all the buttons
and the rotary switch on the instrument are non-functional except for the OFF
position.
FUSE -G-: Flashes if the “G” input fuse is defective.

The button allows automatic measurement of:
Dielectric Absorption Ratio (DAR).
Polarization Index (PI).
Dielectric Discharge Test (DD).
The PI and DAR values are useful on long cables or when monitoring aging
insulation on electrical machines.
interfering currents (from capacitive charges, dielectric absorption), which
eventually cancel each other out. In order to get an accurate measurement of the
leakage current, it is necessary to perform the measurement over a long period
measurement.
Then, the or the ratios are calculated:
PI* = R10 min / R1 min (2 values recorded during a 10-minute measurement).
DAR = R1 min / R30 s (2 values recorded during a 1-minute measurement).
The quality of insulation depends on the results found.
State of the insulation
< 1.25 < 1 Inadequate, even dangerous
< 2
< 1.6 Good
Excellent
If one layer is defective but all the others show strong resistance for multi-layer
of problem.
Therefore, a dielectric discharge test (DD) is necessary to supplement the PI and
DAR indications.
This test measures the dielectric absorption of heterogeneous or multi-layer
insulation while ignoring the parallel-surface leak currents.
the insulation to be measured (a typical value is the application of a 500 V
voltage for 30 minutes).
The test voltage is chosen in the same way as the insulation measurement in the
SET-UP menu. The device will cause a fast discharge during which the insulation
capacity is measured and measured again 1 minute after the residual current is
circulating in the insulation.

First Function -
Turns the display back-light ON or OFF.
Second Function - ALARM
Activates/deactivates the ALARM function. The “ALARM” symbol is displayed
when activated.
If activated and the high or low threshold values are programmed, the “ALARM”
threshold is crossed.
Activating the Alarm Indication before a Test:
To activate the Alarm Indication before performing a test you must go through the
following steps:
Program the Alarm Set Point Resistance Value for the Test Voltage that you
will use.
Turn the Rotary switch to the Setup position.
Press the Yellow 2nd button. Then, press the Alarm button to set Alarms. The
nd & Alarm you will see the alarm setting for 50 volt tests.
Press the 2nd & Alarm buttons repeatedly until you see the test in the top line
of the display that you wish to set alarms for. The sequencing will be 500,
1000, 2500, 5000, and set.

Press the Right Arrow Key again to move to the Resistance Value Set Point
Selection. You can change this value digit by digit using the Up Arrow / Left
Arrow combination working from the highest to lowest digit.
