DATA HOLD, MAX-MIN, and PEAK Modes 

1. 

Measure current or voltage as previously described. 

2. 

Press the HOLD button to access the Data Hold mode; an 

H

 icon will be displayed. 

Use the Data Hold mode to freeze a displayed reading.  

3. 

Press again to access the MAX mode. In the MAX mode, only the highest reading will 
be displayed. The MAX icon will be indicated on the LCD display. 

4. 

Press again to access the MIN mode. In the MIN mode, only the lowest reading will 
be displayed. The MIN icon will be indicated on the LCD display.

the LCD display. 

6. 

Press and hold the HOLD button for 3 seconds to return to the normal operating 
mode. 

Note: The sampling time of the PEAK Mode is 39µS (50Hz) or 33µS (60Hz). 

HOLD, MAX and MIN display the TRMS value 

 

Automatic Power OFF 

In order to conserve battery life, the meter will automatically turn off after approximately 15 
minutes. To turn the meter on again, turn the function switch to the OFF position and then 
to the desired function position. 

 

To defeat the Auto Power OFF feature, press and hold the
