GENERAL INSTRUCTIONS
Control Locations
For a diagram of the Model 310-TEL, please refer to
page 14.
Test Leads
Check the test leads periodically. Leads that are worn,
have damaged insulation, damaged plugs, damaged
probes or loose parts should be replaced.
The following section should be read carefully. It con-
tains instructions and precautions to be observed in
making measurements with the tester.
The alligator clips provided with the tester fit over the
end of the test probes. When measuring high volt-
age, these alligator clips allow measurement without
handling the test probes. ALWAYS SHUT OFF THE
POWER source before attempting to connect alligator
clips.
Range Selection
When the approximate value of the quantity being mea-
sured is not known, ALWAYS START ON THE HIGH-
EST RANGE. For greater accuracy, choose the range
which will allow readings to be taken in the upper (right
hand) portion of the scale. See Operation Chart on
page 25.
