Maintenance

Maintenance
Clean the Product
Caution
To prevent possible damage to the Product or to equipment
under test, do not use abrasive cleaners. They will damage the
case.
Regularly wipe the case with a damp cloth and weak detergent.
To clean the Product Jaw:
1. Examine the jaw-mating surface to make sure it is clean. If there is unwanted
material (including rust), jaw closure will not be correct and there will be
measurement errors.
2. Open the jaws and clean the clamp metal ends with a non-flammable oil and cloth.
Battery Replacement
 Warning
To prevent possible explosion, fire, or personal injury, replace
the batteries when the low battery indicator (B) shows to
prevent incorrect measurements.
Caution
To prevent possible damage to the Product or to equipment
under test:
• Remove batteries to prevent battery leakage and damage to
the Product if it is not used for an extended period.
• Be sure that the battery polarity is correct to prevent battery
leakage.
To change the batteries, see Figure 2:
1. Make sure the Product is off.
2. Turn over the Product to access the battery compartment door screw.
3. Use a flat-head screwdriver to loosen the battery compartment door screw and lift off
the battery compartment door.
4. Replace the two AAA batteries. Make sure to use the correct polarity when you put
the batteries into the battery compartment door.
5. Reattach the battery compartment door.
6. Tighten the battery compartment door screw.
