Battery test
•
Connect the red lead to the
(+) V
Ω
A
input.
•
Connect the black lead to the
(–) COM
input.
•
Select the proper range for the type of battery to be used.
•
For “AAA”, “AA”, “C” and “D” type batteries, select the 1.5V range.
•
For rectangular 9V batteries, select the 9V range.
•
Connect the black lead to the negative terminal of the battery.
•
Connect the red lead to the positive terminal of the battery.
•
The BAT scale at the bottom of the meter display will show GOOD, REPLACE or
Questionable status.
•
Please note that this will only provide relative battery condition results. The actual
usefulness of a specific battery in a given application will depend upon the current
requirements of that application. This tester provides the following reference loads:
▪
9V, 30mA
▪
1.5V, 300mA
Transistor Type Check
•
This meter will identify whether a given transistor is PNP or NPN.
•
Insert the transistor into the correct socket inputs labeled Emitter, Base and Collector.
•
Select the TR position on the Range Selector
•
The red LED will indicate a PNP transistor, the green LED indicates NPN
Cleaning and General Maintenance
•
Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives
or solvents.
•
Periodically terminals and test probes standard spray contact cleaner as dirt and
moisture affect readings.
•
Turn the Meter to OFF position when it is not in use and remove the batteries if the
meter is not to be used for a long period of time.
•
Do not attempt to repair or service your Meter unless you are qualified to do so and
have the relevant calibration, performance test, and service information.
•
To avoid electrical shock or damage to the Meter, do not allow water inside the case.
•
Do not store the Meter in a place of high humidity or temperature
Battery Replacement
•
When using the OHMS scale, if the meter cannot be calibrated to the Zero position,
the batteries should be replaced.
•
Make certain the test leads are removed from the circuit under test and disconnected
from the meter.
•
Remove the three Philips head screws from the rear of the meter housing
•
Remove the rear housing from the meter assembly.
•
Locate and replace the three batteries inside the meter (2x AA, plus 1x 9V).
•
It is recommended that only good quality alkaline batteries be used.
