Page 9: Insulation Resistance Testing Principal Of Operation
Insulation Resistance Testing Principal of Operation Insulation resistance measurement is based on Ohm’s Law. By applying a known DC voltage and then measuring the current flowing, the instrument can determine the value of the resistance. In principle, the value of the insulation resistance is very high, but not infinite. Therefore, by measuring the low current flowing, the instrument indicates the insulation resistance value, providing a result in kΩ, MΩ, or GΩ. -
Page 10: Test Button And Function Keys
TEST Button and Function Keys 2.4.1 TEST Button Pressing the TEST button starts an insulation measurement. It also serves to confirm a programmed threshold. • Performs battery voltage check (§3.2) • In resistance measurement, it is used to enter/exit the DMR mode and record the reference measurement (§3.7.1) •... -
Page 11: Terminals
Terminals Ω FUSED The instrument has two measurement terminals: + (positive) and COM (common). 700 V Configuration Mode Configuration mode enables you to set several options for the instrument. To open configuration mode, turn the rotary switch to OFF. Then press and hold down the SET-UP key for >2s while turning the rotary switch to any position. -

3.6.1 Compensation of the Measurement Leads Ω Short the input terminals by touching them together. Then press the key and hold it down for >2s. The LCD should display 0Ω. If current is 0 mA when the terminals are shorted, verify the fuse is good. NOTE: If the resistance of the leads is >5Ω, compensation is not possible. -

4. The threshold percentage can be set from 0.1% to 399.9%; default is 5%. When finished setting the threshold percentage, press TEST to exit SET-UP mode. 5. Connect the red lead to the terminal and the black lead to the COM terminal. 6. - Page 19 The other test types are selected via the SET-UP key: DESCRIPTION Lock the TEST button. In this mode, after you start the measurement, it continues without requiring you to keep the TEST button pressed. The test will press run until you stop it, or when 40 minutes have passed. Activate timed test mode.
- Page 20 6. When performing insulation measurement, you can press the key to enable the alarm feature. If the measurement falls below the alarm threshold, the alarm will activate. To set alarm threshold (§2.12). 7. At the end of the test, either release the TEST button (for unlocked tests) or press the TEST button a second time (for tests).
- Page 21 IEEE-43 recommends that good insulation will exhibit an increase in resistance at the 10-minute point that should be at least two times greater than the measurement taken at the one-minute point. Therefore, healthy insulation will exhibit a PI ratio of 2 or higher. Newer insulation material can progress through the absorption phase very quickly and therefore display a PI ratio of 1.
- Page 22 3.8.2.3 Conducting a Dielectric Absorption Ratio (DAR) Test The dielectric absorption ratio test is typically accomplished by measuring the insulation resistance taken at the 30 second time interval and comparing it to the insulation resistance measurement at the 60 second time interval. The instrument allows user programming of both time points if necessary.
- Page 23 3.8.2.5 Performing a Timed Test 1. Turn the rotary switch to an insulation voltage setting. Choices are 250V, 500V, 1000V (available on both the Models 6528 and 6529), and 50V and 100V (available on the Model 6529 only). The test voltage to select depends on the voltage of the installation to be tested.

4. MAINTENANCE The instrument has no parts that can be replaced by personnel who are not trained and approved. Any non-approved repair or other work, or replacement of a part by an “equivalent,” may severely compromise safety. Cleaning Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture in the terminals can affect the readings. -
