Cleaning 
Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives, 
isopropyl alcohol, or solvents.  
XWWarning 
To avoid electrical shock or damage to the Meter, never allow 
water inside the case. To avoid damaging the housing, never 
apply solvents to the Meter. 
Dirt or moisture in the input terminals can affect readings and can falsely activate the 
Input Alert feature. Clean the terminals as follows: 
1.  Turn the Meter off and remove all test leads. 
2.  Shake out any dirt that may be in the terminals. 
3.  Soak a clean swab with mild detergent and water. Work the swab around in each 
terminal. Dry each terminal using canned air to force the water and detergent out of 
the terminals. 
Performance Tests 
The following performance tests will ensure that the Meter is in proper operating 
condition and will check the accuracy of each meter function against its specifications. 
To perform the tests you will need a Fluke 5520A Calibrator or equipment meeting the 
minimum specification given in Table 2. Prior to beginning the accuracy tests, allow for 
the Meter to stabilize to room temperature. Depending on temperature gradient this could 
take up to several hours. 
If the Meter fails any of these tests, it needs calibration adjustment or repair.
