5-1 Start-up Inspection
Check the following items before starting the daily measurement work.
• Appearance check : Check the appearance of the tester to see
if it is free from damage caused by falling, etc.
• Accessories : Check that the test leads and alligator clips are
free from irregularities such as wire disconnection and crack.
• Batteries : Install the batteries before using the tester for the

batteries with new ones.(see 6-4)
* If nothing is displayed, the batteries may be exhausted totally.
• Also check that the tester and your hands are not moistened
by water, etc.
5-2 Interference voltage measurement (ACV)
Function Measurement range
Accuracy
Remarks
ACV
0.0~400.0 V
±(2 %rdg+3 dgt)
OL indicates on
the display when
400.0 voltage or
more input.
* The accuracy-guaranteed: 40~500 Hz
Procedure :
①
Connect the black test lead plug into E terminal and blue test
lead plug into S(P) terminal.
②
Set the function to AC V.
③
Connect the test leads to the object measured.
④
Read the displayed value (there is no need of pressing the TEST button).
Notes :
• The interference voltage is higher than 10 V, the earth
resistance measurement can not be performed.
• DC element in interference voltage is not detected in this
function.
