5.  MAINTENANCE 

This meter is a precise instrument. Any modificaDon to the circuit is not allowed. 
NOTE: 

i.

Don’t  input  the  voltage  value  higher  than 
600V DC or AC  rms. 

2) Don’t input voltage at current, resistance, diode or conDnuity range. 
3) Don’t  make  any  measurements  when  the  ba]ery  is  not  properly  installed  or  the 

back cover isn’t fixed. 

4) Before  replacing  ba]ery  or  fuse,  please  remove  the  test  leads  from  the  measuring 

point and turn off the power. 

5) Keep the meter away from water, dust and shock. 
6) Don't  expose  the  meter  under  high  temperature,  high  humidity,  combusDble, 

explosive and strong magneDc place. 

7) Wipe the case with a damp cloth and detergent. Do not use abrasives and alcohol to 

clean the meter. 

8) If  the  meter  will  not  be  used  for  a  long  Dme,  please  take  out  the  ba]ery  to  avoid 

leakage damage. 

9) When  “

”  symbol  is  displayed,  please  replace  the  ba]ery  according  to  the 

following steps: 

① Remove the holster at first. 
② Screw off the fixing screws of the ba]ery door and remove the cover; 
③ Take off the old ba]ery and replace with a new one. To extend the using life, it's 

be]er to use alkaline ba]ery. 

④ Fix the ba]ery door. 
⑤ Put on the holster. 

10) Fuse  replacement:  When  replacing  fuse,  please  use  fuse  with  same  type  and 

specificaDon. 

① Remove  the  holster  first,  then  screw  off  the  fixing  screws  of  the  ba]ery  door 

and back cover to remove the cover; 

② Take off the old fuse and replace with a new one. 
③ Install  the  back  cover,  then  fix  the  screws  of  the  ba]ery  door  and  back  cover. 

Put on the holster.
