Backlighted display 

Press the 

SELECT

 button for 1 second or more to turn on or off the display backlight function. It will 

also be turned off automatically after 30 seconds to extend battery life. 

 
Manual or Auto-ranging 

Press the 

RANGE

 button momentarily to select manual-ranging mode, and the meter will remain in the 

range it was in, the LCD annunciator 

  turns off. Press the button momentarily again to step 

through the ranges. Press and hold the button for 1 second or more to resume auto-ranging mode. 
Note: Manual ranging mode feature is not available in Hz function. 
 

Hold

 

The hold function freezes the display for later view. Press the 

HOLD

 button momentarily to 

activate or to exit the hold function. 
 

Set Beeper Off 

Press the 

Hz

 button while turning the meter on to disable the push button operating beeper 

feature. However, the continuity and Jack Beep input warning features remain. 
 

Beep-Jack™ Input Warning 

The meter beeps as well as displays “

InErr

” to warn the user against possible damage to the meter 

due to improper connections to the 

A, mA, or A input jacks when other function (like voltage function) 

is selected. 

 
Intelligent Auto Power Off (APO) 

The Intelligent Auto Power Off (APO) mode turns the meter off automatically to extend battery life after 
approximately 17 minutes of no activities. Activities are specified as: 1) Rotary switch or push button 
operations, and 2) Significant measuring readings of above 10% of range or non-OL 

 readings. In 

other words, the meter will intelligently avoid entering the APO mode when it is under normal 
measurements. To wake up the meter from APO, press the 

RECORD

 button momentarily or turn the 

rotary switch to the OFF position and then turn back on again. Always turn the rotary switch to the OFF 
position when the meter is not in use. 
 

Disabling Auto Power Off

 

Press the 

RANGE

 button while turning the meter on to disable the Auto Power Off (APO) feature.
