Basic Maintenance
This section contains information about the basic maintenance of the Tester.
 Warning
To prevent possible electrical shock, fire, or personal injury:
• Remove the input signals before you clean the product.
• Remove all probes, test leads, and accessories before the
case is opened.
• Use only specified replacement parts.
How to Clean the Tester
 Warning
To prevent electrical shock or damage to the Tester, never
allow water inside the case.
 Caution
To prevent damage to the housing, never apply abrasives or
solvents to the Tester.
Periodically wipe the case with a damp cloth and mild detergent. Dirt or moisture in the
input jacks can affect readings.
To clean the input jacks:
1. Turn the Tester off and remove all test leads.
2. Shake out any dirt that may be in the input jacks.
3. Soak a new swab with alcohol. Work the swab around each input jack.
How to Test and Replace the Batteries
The Tester continuously monitors Battery voltage. If the voltage falls below 6.0 V (1.0
V/cell), the low battery icon () appears on the display, indicating that there is
minimal battery life left. The low battery icon continues to appear on the display until
you replace the batteries.
 Warning
Replace the batteries when the low battery indicator shows to
prevent incorrect measurements.
Replace the batteries with six AA batteries. Alkaline batteries are supplied with the
Tester but you can also use 1.2 V NiCd or NiMH batteries. You can also check the
battery charge so that you can replace them before they discharge.
To test the batteries:
1. Turn the rotary switch to the V position.
2. Press  to initiate the battery test. The Voltage function display clears and is
replaced by the measured battery voltage in the secondary display for 2 seconds, the
Voltage function display then returns.
To replace the batteries (refer to Figure 1):
1. Press  to turn off the Tester.
2. Remove the test leads from the input jacks.
3. Remove the battery door by using a standard-blade screwdriver to turn the battery
