Relative Mode 

The  relative  measurement  feature  allows  you  to  make  measurements  relative  to  a  stored 
reference  value.  A  reference  voltage,  current,  etc.  can  be  stored  and  measurements  made  in 
comparison to that value. The displayed value is the difference between the reference value and 
the measured value. Note: Relative mode does not operate in the 4-20mA function. 
1. Perform the measurement as described in the operating instructions. 
2. Press the REL button to store the reading in the display and the "REL" indicator will appear on 
    the display. 
3. Left auxiliary display displays the margin of initial value and the current value. Right auxiliary 
    display displays the initial reading. Main display the reading after REL TEST. 
4. Press the EXIT button to exit the relative mode.

Display Backlight 

Press the 

 key to turn the backlight on. The backlight will automatically turn off after SET time. 

Press the EXIT button to exit the backlight on mode.

HOLD 

The hold function freezes the reading in the display. Press the HOLD key momentarily to activate 
or to exit the HOLD function. 

3.21 

PEAK HOLD 

The Peak Hold function captures the peak AC or DC voltage or current. The meter can capture 
negative  or  positive  peaks  as  fast  as  1  millisecond  in  duration.  Momentarily  press  the  PEAK 
button, “PEAK” and “MAX” will display in left auxiliary display. MIN” will display in right auxiliary 
display.  The  meter  will  update  the  display  each  time  a  lower  negative  peak  occurs.  Press  the 
EXIT button to exit the PEAK HOLD mode. Auto Power Off feature will be disabled automatically 
in this mode.

Data Record (Store/Recall) 

1. STORE function 
In the current testing mode, press STORE button one time, enter into STORE function. On the 
left  upper  corner  of  LCD  shows  NO XXXX.,  which  states current storage  serial  number. Then, 
press button PEAKHOLD to change into the initial serial number 0000. (Press again it will change 
back). On the right upper corner of LCD shows XXXX, which states how many current storage is 
used. Press STORE button again, enter into recording interval time set up function. On the left 
upper shows 0000 S, which states recording interval time; using  & - to select, the range 
is 0~255 seconds. When the recording interval time is 0000 S, then press STORE button again 
to  change  into  manual  recording.  Press  the  STORE  button  again  to  record  once.  When  the 
recording interval time is 1~255 S, then press STORE button again to start recording automatically 
from 0000. Recording times is showed on the left upper corner, data is showed on the right upper 
corner  (Due  to  digital  limitation,  there  is  only  display  preceding  four  numbers)  To finish  above 
STORE function, press EXIT button shortly. If you expect to clear all memory data: While power 
on, hold EXIT button, and switch from OFF to random and then release EXIT button, the LCD will 
flash thrice and buzzer thrice too, which means all memory data is cleared.
