G. TROUBLE SHOOTING GUIDE

Problem

Probable Causes

Does not power up

• Dead or defective battery
• Broken wire from battery 

snap to PCB

Won’t display current readings

• Open fuse
• Open test lead
• Improperly connected to 

circuit under test

All functions except ohms read high

• Very weak battery that will 

not turn on the low battery 
indicator on the LCD

ACV do not read

• Very weak battery that will 

not turn on the low battery 
indicator on the LCD

WARRANTY

Please refer to product warranty card for warranty
statement.

F. MAINTENANCE

1.

Battery Replacement:

The DMM 196 will display AT

when the 9 volt battery needs replacement. Battery
replaced as following:

a. Disconnect and remove all test leads from live circuit

and from DMM 196.

b. Remove DMM 196 from protective boot.

c. Remove the three screws from battery cover of back

d. Remove old batteries and replace with new batteries.

e. Reassemble instrument in reverse order from above.

2. 

Fuse Replacement:

Both the A and mA/uA input jacks

are fuse protected. Use only Fast blow, 600V fuses with
correct current ratings. Failure to do so will void all
Warranties. If either do not function, replace as Following:

a. Disconnect and remove all test leads from live circuit

and from DMM 196.

b. Remove DMM 196 from protective boot.

c. Remove the three screws from battery cover of back

d. Remove old fuse(s) and replace it with new fuse(s).

e. Reassemble instrument in reverse order from above.

f. Fuse must be changed by replacement in service center.

3.

Cleaning your DMM 196

Use a mild detergent and a slightly damp cloth to clean the
surfaces of the DMM 196.
