• 

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 M

Ω

 or G

Ω

. 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 M

Ω

, 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.
