WARNING 
To avoid electrical shock, disconnect the meter from any circuit, remove the test leads 
from the input jacks and turn OFF the meter before opening the case. Do not operate 
with open case. 
 
Trouble Shooting 
If the instrument fails to operate, check batteries and test leads etc., and replace as 
necessary. Double check operating procedure as described in this user’s manual 
 
If the instrument voltage-resistance input terminal has subjected to high voltage 
transient (caused by lightning or switching surge to the system) by accident or abnormal 
conditions of operation, the series fusible resistors will be blown off (become high 
impedance) like fuses to protect the user and the instrument. Most measuring functions 
through this terminal will then be open circuit. The series fusible resistors and the spark 
gaps should then be replaced by qualified technician. Refer to the LIMITED 
WARRANTY section for obtaining warranty or repairing service. 
 
Cleaning and Storage 
Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives 
or solvents. If the meter is not to be used for periods of longer than 60 days, remove the 
batteries and store them separately  
 
Battery replacement 
The meter uses standard 1.5V AAA Size (NEDA 24A or IEC LR03) battery X 2
