General Information regarding Insulation Measurement
For electrical installations the insulation measurement has to be carried out prior to final
commissioning. This measurement is of basic importance as the insulation measurement
(protection against dangerous body currents) is considered to be the only measurement for
fire protection. If, due to an insulation error, a limited fault current flows between two
conductors, this leads to a heating up or even to a fire. Only the insulation measurement
procedure can detect such a fault.
According to DIN VDE 0100 Part 610 the insulation resistance measurement is carried out:
• from all external conductors (e.g. B. L1, L2, L3) towards ground or towards the grounded
protective earth (PE)
• between protective earth (PE) and neutral (N)
Additionally, it is advised to perform the following measurements:
• between all active conductors (e.g. L1, L2, L3, N).
This measurement has to be carried out separately for every individual current circuit. This
measurement is performed using a DC voltage of 500 V.

Performance of Measurements
Insulation Measurement
The Amprobe ISO-PRO generates the test voltage as pre-set via the measurement function
selection dial (19) at the connection socket RISO (14). A current-voltage measurement is used
to determine the respective insulation resistance.
A built-in automatic device calculates the current measurement value within a few seconds.
Thus, a multitude of measurements may be carried out saving time and battery power. The
measurement time depends on the insulation resistance measured and on the capacity.
WARNING
• Prior to any insulation measurement ensure that the system parts to be tested are not live.
Failure to respect this prescription can cause instrument damage.
• During insulation measurement all loads must be disconnected from the mains.
Furthermore, ensure that all interrupters of the system being tested are switched on.
• During the measurement the UUT/the system being tested may not be touched. Danger of
electrical shock!
• The insulation measurement causes the capacitance UUTs to be charged by test voltage.
The Amprobe ISO-PRO automatically discharges the UUT after the completion of
measurement. When interrupting the measurement or when removing the test leads prior
to the completion of measurement, a dangerous voltage may be present and remain at
UUT. If a dangerous voltage is detected during voltage measurement, the UUT must be
discharged manually, using a high-resistant load (not via short-circuit!).
• The RISO connection socket is supplied from the instrument with a voltage of < 1kV within
the RISO 1000 V measurement range.
1) Set the measurement function selection dial (19) to one of the four ”RISO
measurement functions" (1000 V/ 500 V/ 250 V/ 100 V).
2) Connect the red test lead to the ”RISO" socket and the black test lead to the ”COM"
socket.
• 3 different limit values (0.5/1.0/2.0 MΩ) can be set using the ”LIMIT" key (16).
• Resistance values between 0.005 MΩ and 1.999 GΩ can be measured within all four
insulation measurement ranges.
4) Now connect the test leads to UUT.
5) Press the ”Start" key (20). The measurement is started.
12
• Ensure correct and clean contact to UUT . A bad contact to UUT may cause the interruption
of the measurement.
• The test voltage remains present at UUT until the ISO-PRO has determined the insulation
resistance value or as long as the "Start” key (20) is pressed.
• During the measurement the symbol of the measurement unit (MΩ/GΩ) is displayed.
• If the measurement value falls below the pre-set limit value, a signal is audible after the end
of the measurement and the ""-symbol appears.
• To store the measurement result, press the "Save” key (21).
• The measurement value remains displayed until the start of a new measurement procedure
or until a different measurement range is selected.
• The UUT is automatically discharged after the measurement. During this time the symbol
of the measurement unit is blinking.
External voltage protection for insulation resistance measurement range.
If a external voltage of maximum 1200 V is connected by mistake to the insulation
measurement socket, the ISO-PRO will not be damaged.
The instrument display indicates +”UEXT". After removal of the external voltage wait for
approx. 30 seconds. Only then correct measurement results will be indicated.
13
Timer Measurement
The Timer measurement, in particular together with the limit value monitoring, is a capable
tool to quickly test the insulation resistance of a multitude of conductors with reference to
the protective conductor.
To carry out the Timer measurement, press the Start key. The measurement is carried out
until the pre-set timer period has elapsed. Three different measurement times are available:
10 s, 30 s, 180 s.
1) For the measurement procedure, please refer to the insulation measurement.
2) The pre-set measurement time (0 s, 10 s, 30 s or 180 s) is indicated briefly when
pressing the "Timer” key (18).
• During the Timer period display, this time can be extended by pressing again the "Timer”
key (18) (respectively 0-10-30-180-0, etc.).
• During active timer function the ‘Timer‘ symbol is displayed on the screen.
3) The timer function is switched off by selecting the time 0s. The ‘Timer‘ symbol goes
out. The pre-set time is maintained even after the instrument is switched off.
• Connect the UUT to the measurement instrument. In case a limit value monitoring has to
be performed, select the respective limit value by means of the ‘Limit‘ key.
• The Timer measurement is started pressing the "Start” key. During the time that the test
voltage is present at UUT the symbol of the measurement unit (MΩ/GΩ) is blinking.
• The limit value monitoring is permanently carried out during limit value monitoring, i.e. if
the measurement value falls below the limit value. This condition is indicated by an acoustic
signal and the display of the respective symbol.
• The Timer measurement is interrupted when pressing the "Start” key . A confirmation signal
is audible. The UUT is automatically discharged upon completion of the measurement,.
The measurement unit symbol is also blinking during this procedure.
14
Acoustic control during Timer Measurement Timer measurement
If the measurement value changes for the first time from the overflow (>1.999 GΩ) to a value
< 2.000 GΩ, a brief signal sound is audible as confirmation for having connected a UUT . If the
insulation resistance falls below the pre-set limit value, an additional signal (continuous signal)
is audible, whereby the signal level is clearly different from the first signal sound. Thus, it is
possible to test the insulation of several current circuits. The ISO-PRO is connected to a
protective conductor via a cable. The second cable will be equipped with a test probe. Test
voltage and Timer duration will be set. The limit value will be selected. Then, the
measurement is started pressing the Start key. The user hears a brief acoustic sound when
connecting the test probe to a current circuit. During the measurement of the subsequent
current circuit, a further brief signal sound is audible, etc. If the insulation resistance of a
current circuit is too low, the user hears a continuous sound during the time, the test probe
is measuring the faulty current circuit.
• If no brief signal sound is audible during the measurement of a current circuit, either the
timer duration has already elapsed, or the measurement value amounts to > 1.999 GΩ, or
the measurement instrument has not yet displayed the overflow between two
measurements.
• The last measurement value remains displayed until a new measurement procedure is
started or a different measurement range is selected.
Limit Value (LIMIT)
Repeated pressing of the ”LIMIT" key (16) allows the setting of 3 limit values for the
insulation measurement, or to switch off the limit value monitoring.
The set limit value is displayed. If the measurement value falls below a pre-set value, a
warning signal is audible and the respective symbol is displayed.
15
Resistance Measurement LOW-Ω
The Amprobe ISO-PRO generates a test voltage at the connection socket LOW-Ω (10). A
current-voltage measurement is used to determine the respective resistance. The
measurement is used to check protective earth conductors, ground conductors, or
equipotential bonding conductors for low-ohm continuity.
WARNING
Prior to any resistance measurement, it must be ensured that the system parts to be tested
are not live. Failure to respect this prescription can lead to instrument damage.
• Prior to any resistance measurement it is possible to compensate the test leads, please refer
to section 6.2.1.
1) Set the measurement function selection dial (19) to measurement function
”LOW-Ω".
2) Connect the red test lead to the ”LOW-Ω" socket and the black test lead to the
”COM" socket.
3) Connect the test leads to the UUT.
4) Press the ”Start" key (20) to start the measurement.
5) Read the measurement value displayed on the screen.
• The measurement value remains displayed until starting a new measurement procedure or
until selection of a different measurement range.
• Erroneous measurements results may be generated by impedance installed in parallel of
additional operation current circuits and by compensation currents.
16
External voltage protection for LOW-Ω measurement range
If a external voltage of maximum 600 V is connected by mistake to the LOW-Ω measurement
socket, the LOW-Ω measurement will not be carried out. The instrument display indicates
+”UEXT".
• For voltages > 600V AC/DC the internal fuse will trip.
Test Lead Compensation
The ISO-PRO allows the compensation of the test lead resistance and the additional
measurement accessories. Proceed as follows:
1) Set the measurement function selection dial (19) to measurement function ”LOW-Ω".
2) Connect the black test lead to the "COM” socket and the red test lead to the ”LOWΩ" socket.
3) Short-circuit both test leads connected.
4) Press the "COMP” key (26).
5) The measurement is started. The test lead resistance is measure and compensated.
The "COMP” symbol (7) is displayed. 0,00 Ω appears on the display and an acoustic
signal is audible
• If a value exceeding 1.99 Ω is measured, no test lead compensation is carried out. In lieu of
the measurement ">1.99 Ω” is displayed together with the respective symbol and a double
acoustic signal is audible.
• To delete the test lead compensation, press again the ”COMP" key (26). The "COMP”
symbol disappears.
17
Function UProtection Level
The ISO-PRO allows the measurement of the protection level or the response voltage of
overvoltage protection devices. The measurement consists in the DC voltage measurement.
The resulting DC value agrees with the actually measured DC voltage.
Signification of AC voltage value:
The AC value displayed agrees with the rms value of the AC voltage allowing the connection
of verified overvoltage protection devices.
To calculate the maximum AC voltage, a safety factor of approx. 14 % is considered, resulting
in the formula UAC = UDC / 1.6.
WARNING
• A measurement may only be carried out on system parts not being live!!
• During protection level measurement, all loads must be disconnected from the mains.
1) To carry out this measurement, connect the overvoltage protection module to ‚Riso‘
and ‚COM‘ sockets.
2) Set the measurement function selection dial (19) to position UProtection Level.
3) Start the measurement pressing the "Start” key (20).
• The ‚AC DC‘ key ( 17) is used to choose between the measurement result display as DC or
as AC voltage.
• The measurement value displayed after completed measurement can be saved pressing
the ‘Save’ key (21) .
• The instrument is resistant against external voltages up to a value of 1200 V.
18
AC/DC Voltage Measurement
Connected loads generating EMV disturbance or harmonic waves may impair the display
quality.
1) Select the ”UAC/DC" measurement range using the measurement function selection
dial (19).
2) Connect the red test lead to the "UAC/DC" socket and the black test lead to the
"COM" socket.
3) Connect the test leads to the UUT.
4) Select between AC or DC voltage pressing the ”AC/DC" key (17).
• When switching on or changing to the "UAC/DC" measurement function, the default
setting is always "AC".
5) Read the measurement result on the display screen.
Overvoltage Protection for Voltage Measurement
If a external voltage of maximum 600 V AC/DC is connected by mistake to the UAC/DC
measurement socket, ISO-PRO will not be damaged. The instrument displays ">600V”. After
removal of the overvoltage wait for approx. 20 s to obtain correct measurement values.
• If an AC voltage >25 V is measured within the DC voltage range, the instrument displays
"Uext”.
• This is also valid for the AC range if measuring a DC voltage > 25 V.
19

error signal is emitted, if no measurement value has been stored in the memory.
Limit Value Signal
The sound level of this signal is different from the confirmation signal or from the error
signal, the sound level is higher . It indicates that the measurement value falls below the preset limit value. It is audible either at the end of a measurement or during Timer measurement.
Energy Management
Approximately 5 minutes after the last key pressing the instrument switches off automatically .
(auto power off). The instrument returns in operation mode when turning the measurement
function selection dial (14) from position "OFF” or when pressing the "Start” key (20).
Maintenance
When operating the instrument in compliance with the instruction manual, no particular
maintenance is required.
Cleaning
If the instrument is dirty after daily usage, it is advised to clean it by using a humid cloth and
a mild household detergent.
WARNING
Prior to cleaning, ensure that instrument is switched off and disconnected from external
voltage supply and any other instruments connected (such as UUT , control instruments, etc.).
Never use acid detergents or dissolvants for cleaning.
After cleaning, do not use the voltage tester for a period of approx. 5 hours.

Battery Replacement
WARNING
• If the battery symbol appears on the display, the battery must be replaced.
• Prior to battery replacement disconnect the instrument from all connected measurement
circuits and test leads.
1 ) Switch off the instrument by means of the measurement function selection dial (19)
and disconnect from all measurement circuits.
2) Unscrew the screws on the instrument rear.
3) Lift battery case cover (by slightly knocking with the ??ball of thumb).
4) Remove discharged batteries.
5) Insert new batteries respecting correct polarity (indicated on the bottom of the
battery case) !
• Never use other batteries than specified in the Technical Data section (1.5V Type IEC LR6,
Mignon).
6) Replace battery case cover and retighten the screws.
7) The instrument is ready for operation.
• Only use accumulators as described in the technical data section!
• Please consider your environment when you dispose of your one-way batteries or
accumulators. They belong in a rubbish dump for hazardous waste. In most cases, the
batteries can be returned to their point of sale.
• Please, comply with the respective valid regulation regarding the return, recycling and
disposal of used batteries and accumulators..
If an instrument is not used over an extended time period, the accumulators or batteries must
be removed. Should the instrument be contaminated by leaking battery cells, the instrument
has to be returned for cleaning and inspection to the factory.

Built-in Fuse
The built-in fuse protects the Low Ohm function if the instrument is connected to voltage
during running measurement. This fuse may also trip if voltages > 600 V AD/DC are connected
to the measurement instrument.
WARNING
• The fuse replacement may only be carried out by authorised staff.
• Exclusively use fuses of voltage, current and breaking capacity values in compliance with
the technical data section.
• Using temporary fuses, in particular short-circuiting fuse holders is prohibited and can cause
instrument destruction or serious bodily injury of operator.
• Prior to fuse replacement disconnect the instrument from all measurement circuits and
test leads.
Error Message after Fuse T ripping
If the message 'Fus' appears on the LCD during the measurement in the Low Ohm function,
the fuse has tripped and must be replaced. Please contact our repair service department.
Description of Appropriate Fuse
Fuse Type F 500 mA / 500 V, 6.3 x 32 mm
Calibration Interval
We suggest a calibration interval of one year. If the instrument is used very often or if it is
used under rough conditions we recommend shorter intervals. If the instrument is used few
times only the calibration interval can be extended on to 3 years.
