1General Description
This precision instrument is an insulation meter tester and calibrator in one, specifically
designed to test and calibrate insulation test sets and megohm meters with varying ranges.
It consists of a high precision resistance box, a voltmeter and a milliamp meter.
It is constructed from very high insulation materials, including its case, and is fully isolated
from any external circuits including the mains supply.
All of the rotary selector switches are manufactured by Time Electronics, using special high
voltage low leakage wafers; the contacts are self-cleaning. This feature means they should
require no maintenance.
All parts of the instrument, including the bared leads provided (after custom 10 kV rated
probes are fitted) have been tested for safety up to ten kilovolts.
The three functions, Voltage Measure, Current Measure, and Source Resistance are
selected and used separately.
Maximum voltage is dependent upon humidity levels. Below 50% relative humidity is
recommended.

5Operation
5.1 Operational Guidelines
Notes:
1. UUT: stands for Unit Under Test (i.e. the insulation tester or the megohm meter).
2. Wherever possible use the manufacturer of the UUT’s supplied test leads.
The 5069 can measure test voltages generated by a UUT up to 10 kV.
Be aware that the test voltage for high resistance measurements is dangerous and can
cause electric shock!
Always remove the battery charger leads from both the 5069 and the UUT before
starting the calibration setup.
Use only the measuring leads supplied with the UUT or those supplied with the 5069.
When checking high resistance values the leads may pick up electrical interference,
which can cause a disturbance to the readings obtained. Some manufactures fit a
guard connection for use with dedicated leads, this will stabilise the readings.
It is not recommended to operate the resistance decade switches while a test is made.
This will not automatically do any damage but may cause arcing and create transients
which could give false readings on the UUT display due to the fact that the switch is
break-before-make between each resistor. This will ensure that contact arc is
suppressed with high relative humidity.
Avoid opening the 5069 case lid in the rain or in steamy conditions for the moisture
will impair the readings.
Observe safety at all times and if possible, carry out the tests in a low humidity
environment.
Note: Insulation testers will vary, and the controls may be different than those referenced in this manual.
However, the testing principles should still apply.

5.2 Typical Operation Procedure
5.2.1 Initial Setup
1) Check the battery on both 5069 V/I Meter and Insulation Tester.
Make sure their batteries are fully charged.
2) Complete the setup procedure for the insulation tester (UUT).
3) Connect the selected test leads to the 4 mm recessed sockets
of the 5069.
NOTE: If the UUT’s own test leads are available, use them as
first choice.

5.2.2 Voltage Measurement
The 5069 voltmeter will display the voltage output from the insulation tester.
Perform the following procedure to measure the voltage.
1) Adjust the pointer at zero on the UUT (Analogue meter display, if required).
2) On the 5069, select the O/C VOLTS function using the rotator knob.
3) Using ‘Range Selection Button’ under the display, choose the required voltage range:
2 kV or 10 kV.
4) Using the selected high voltage test leads, connect the 5069 to the UUT, observing their
polarities.
5) Select voltage range on UUT, and press the test button.
6) When the reading has stabilised, record the O/C voltage reading on the 5069 voltmeter.

5.2.3 Current Measurement
The 5069 current meter will display the equivalent current output of the Insulation tester.
Perform the following procedure to measure the current.
1) On the 5069, select the S/C CURRENT function using the rotator knob.
2) Using ‘Range Selection Button’ under the display, choose the required current range:
2 mA or 20 mA.
3) Press the test button on the UUT, and record the current reading on the 5069 display.
Ensure the output of the UUT is turned off after test.
4) Return the 5069 setting to O/C Voltage, and repeat the Voltage Measurement procedure
above (5.2.2). This is to check the voltage has recovered. Switch off the output from the UUT.

5.2.4 Insulation Resistance Verification
Note: The O/C V and S/C I display can be turned off when
using the resistance function to conserve battery life.
1) If using the 100 kΩ to 5 MΩ set points, select the required
resistance.
Ensure that the voltage set on the UUT does not exceed this voltage
rating shown on the panel.
2) If using the decades, select the RESISTANCE
function using the rotator knob.
3) Then set the decade resistance knobs to the
value required.
Note the allowed voltage of the resistance ranges as
shown on the 5069 panel.
When using multiple decades, the maximum voltage
is that of the lowest decade.
Ensure that the voltage set on the UUT does not
exceed this voltage rating.
4) Press the test button on the UUT.
Note that on the higher resistance ranges, due to the very low currents present, the
display on the UUT may fluctuate and take time to settle, please follow any precautions
given by the tester manufacturer.
5) Proceed and record all test results, noting the allowed errors of the 5069 and also for that
of the UUT.
