1.
Turn the Range Selector Switch to 1000 ACV.
Always start with the highest range if the voltage is unknown.
2.
Follow the directions on the previous page under DC Voltage Measurements
(except for the polarity directions, they are unnecessary with AC).
1.
Turn the Range Selector Switch to the 250 DCmA & 10A position. Plug the
red lead into the + Jack. Plug the black lead into the DC10A Jack.
Note:
Testing current should ONLY be done in series, with the circuit con-
nected and current flowing.
Note:
The DC10A jack is NOT fuse protected. Only test circuits known to be 10
amps or less.
3.
Carefully connect the test leads to the circuit or the load being tested.
4.
Read measurement. If the Amperage is less than .25A (250mA), disconnect
the leads from the circuit first, then unplug the black lead and plug it into the
-COM Jack. If the Amperage is less than 25mA, set the Range Selector
Switch to the next lower range until the meter pointer is mid-range on the
scale.
5.
When testing is complete, remove Test Leads and store them and the meter
in a safe, dry location.
Circuit resistance can be measured on ranges from meter reading times 1 to meter
Note:
Testing resistance should ONLY be done with the power to the circuit
disconnected. Test to make sure no voltage is present first. If voltage is
applied while testing, disconnect the tester immediately, otherwise the
fuse may blow and the tester may be damaged-see Fuse Replacement
under Maintenance .
Turn the Range Selector Switch to the Ohm testing position (between x1Ω Ω Ω Ω Ω
1.
and x10KΩ Ω Ω Ω Ω ) you will be measuring at.
2.
Plug the red lead into the + Jack. Plug the black lead into the -Com Jack.
3.
Short the Test Leads together. The meter should read "0" Ohms.
4.
If the meter does not read "0" Ohms, the ohmmeter needs to be calibrated to
enable accurate measurements.
a. With the test leads held together, adjust the Ohm Zero Adjust Knob until
the meter's pointer aligns on "0".
