2. General Description
This instrument provides all the equipment necessary to test and calibrate insulation
test sets and megohm meters.
It consists of a high precision resistance box, a volt meter 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.
The switches in the resistance circuit are constructed special high voltage low
leakage wafers and are self cleaning, so should require no maintenance.
All parts of the instrument, including the bared leads provided have been tested for
safety up to ten kilovolts.
The sections of the instrument may be used separately but the user must be aware
that they have a common earth which will prohibit two of the sections being used in
the same circuit.
Maximum voltage is dependent upon humidity levels. Below 50% relative humidity is
recommended.

4. Typical Operation Ins tructions
5069 Ins-Cal Typical Operation Procedure
1) Fully charge the battery in the 5069.
2) Fully charge the battery in the insulation tester (or fit fresh batteries).
3) Complete the set up procedure for the insulation tester (UUT = Unit Under Test).
4) Connect the selected test leads to the 5069 (these are 4mm recessed sockets).
5) Adjust the pointer at zero on the UUT (meter display, if required).
6) Select O/C VOLTAGE setting on 5069 panel.
7) Plug the 4mm connectors into the UUT observing their polarities.
8) Switch on 5069 and select range of voltage measurement (X1/X10).
9) Select voltage range on UUT, and press the test button.
10) When the reading has stabilized record the o/c voltage reading on the 5069 display.
11) Select S/C CURRENT setting on 5069 panel.
12) On the 5069; select the current range (X1/X10).
13) Press the test button on the UUT, and record the current reading on the 5069 display.
14) Return to o/c Voltage setting (8) and repeat the test; (this is to check the voltage has
recovered). Switch off the output from the UUT.
15) Select resistance on the 5069 panel.
16) Set the resistance decade switches on the 5069 to the value required.
17) Note the lowest allowed voltage of the decades set on the 5069, and ensure that the
voltage set on the UUT does not exceed this rating.
Eg, if the 100MΩand 10MΩdecades are set, the highest allowed applied voltage must not
exceed 1KV.
18) Press the test button on the UUT. Please note 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. Proceed and record all test
results, noting the allowed errors of the 5069 and also for that of the UUT.
Insulation Testers will vary from make to make so the controls may be different, however the
principles should still apply.
Observe Safety at all times and if possible, carry out the tests in a low humidity environment.

5. 5069 Ins-Cal Procedural Notes
1. Always remove the battery charger leads from both instruments before starting set up.
2. Use only the measuring leads supplied with the Unit Under Test 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 stabilize the
readings.
3. 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.
4. Avoid opening the 5069 case lid in the rain or in steamy conditions for the moisture will
impair the readings.
