Insulation Testers

Measuring Polarization Index and Dielectric Absorption Ratios (Model 1507)

• The primary display shows ---- until you press the

T button and a valid resistance reading is

obtained.

• The high voltage symbol (Z) along with a primary

display of >30 V warns if voltage greater that 30

V ac or dc is present. If high voltage is present,

the test is inhibited.

5. Press and release T to start the test. During

testing, the secondary display shows the test voltage

applied to the circuit under test. The high voltage

symbol (Z) along with a primary display showing the

resistance in MΩ or GΩ. The t icon appears on the

lower portion of the display until the test is finished.

When the test is completed, the PI or DAR value is

displayed on the primary display. The circuit under

test will automatically be discharged through the

Tester. If either value used to calculate PI or DAR

was greater than the maximum display range, or the

1-minute value was greater than 5000 MΩ, the

primary display will show Err.

• When resistance is higher than the maximum

display range, the Tester displays the > symbol

and the maximum resistance for the range.

• To interrupt a PI or DAR test before it is

completed, momentarily press T. When you

release T, the circuit under test will

automatically be discharged through the Tester.
