Time Electronics 5069 InsCal Insulation Tester Calibrator User Manual

General 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.

All resistors have a temperature coefficient of 250 ppm.

Switches are a purpose-built design, with break-before-make, silver plated, self-cleaning contacts.

NOTE: The maximum voltage applied must be limited to the rating of the lowest decade being used.
For example, if 100 MΩ and 10 MΩ decades are used, the maximum applied voltage will be limited to 1 kV.

Operation

Operational Guidelines

Notes:

UUT: stands for Unit Under Test (i.e. the insulation tester or the megohm meter).
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.

Typical Operation Procedure

Initial Setup

Check the battery on both 5069 V/I Meter and Insulation Tester.
Make sure their batteries are fully charged.
Complete the setup procedure for the insulation tester (UUT).
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.
Typical Operation Procedure

Voltage Measurement

The 5069 voltmeter will display the voltage output from the insulation tester.
Perform the following procedure to measure the voltage.

Adjust the pointer at zero on the UUT (Analogue meter display, if required).
On the 5069, select the O/C VOLTS function using the rotator knob
Using ‘Range Selection Button’ under the display, choose the required voltage range: 2 kV or 10 kV.
Using the selected high voltage test leads, connect the 5069 to the UUT, observing their polarities.
Select voltage range on UUT, and press the test button.
When the reading has stabilised, record the O/C voltage reading on the 5069 voltmeter.

Current Measurement

The 5069 current meter will display the equivalent current output of the Insulation tester.
Perform the following procedure to measure the current.

On the 5069, select the S/C CURRENT function using the rotator knob.
Using ‘Range Selection Button’ under the display, choose the required current range: 2 mA or 20 mA.
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.
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.

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.

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.
If using the decades, select the RESISTANCE function using the rotator knob.
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.
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.
Proceed and record all test results, noting the allowed errors of the 5069 and also for that of the UUT.
