Page 4: Description
1. Description The digital insulation tester model PM5A2 is an advanced insulation analyzer, and it is one of the more complete and sophisticated on the international market. It uses an efficient, carefully tested technology, which provides safe, reliable, and accurate measurements of insulation resistances up to 5 TΩ, with 4 preselected test voltages: 500 V – 1 kV - 2.5 kV – 5 kV. -

4. Connecting the PM5A2 ATTENTION: For safe operation, follow the procedures detailed below with the device Powered-Off. Check if there is no difference of potential voltages between the points where the PM5A2shall be connected to. Also, check the same between those points and the ground. -
Page 10: Use Of "Guard" (G) Terminal
GUARD or R terminals must be grounded, but not both of them simultaneously. Technical Note 32, reproduced at the end of the manual, explains the usage of GUARD terminal in order to eliminate the unwanted resistance effect over the result of measurements. PM5A2... -
Page 11: Setting Tests
Note: Test voltage is the only one parameter that may be modified during tests. 6.2. Selection of the Operation Mode The PM5A2 insulation tester has four operation modes: Normal, with TIMER, SVT, and Pass / Fail. The first three key; the “Pass/ Fail” test mode is activated pressing modes are selected using the key. -
Page 12: Svt Mode (Step Voltage Tests)
6.2.2 SVT Mode (step voltage tests) The use of key allows the PM5A2 setting for the performance of a step voltage test; when this mode is selected, the display shows the SVT abbreviation. Under this operation mode, the user does not define a specific voltage test, but a maximum voltage value. The device will start the test applying a 500 V voltage and increase this value in 500 V steps each minute until reaching the programmed voltage. -
Page 13: Timer Mode
Press keys. Possible values are 10 MΩ, 100 MΩ, 1 GΩor 10 GΩ. During a Pass/ Fail test, the PM5A2 will indicate when the insulation resistance is lower than the programmed limit, both with an intermittent beep and the key led flashing. The key LED will remain flashing until the end of tests, or until the measurement of the resistance value is greater than the programmed limit. -
Page 14: How To Perform Tests
At that moment, the last measured values will remain frozen in the PM5A2 display. By pressing the key again, the equipment will return to the voltmeter function. -

Page 22: Application Note 32
A typical example of this situation occurs when measuring the insulation resistance between primary and secondary windings of a transformer mounted inside a metal housing. Rx: Insulation resistance between primary and secondary winding. R1: Insulation resistance between primary winding and housing. R2: Insulation resistance between secondary winding and housing. PM5A2... - Page 23 Rx = 3000MΩ and R1 = R2 = 100 MΩ, the reading without using the GUARD terminal would be 187.5MΩ, which is quite wrong. On the other hand, if the GUARD terminal is properly used, we would have 3000MΩ. PM5A2...
