4. PRECAUTIONS AND PREPARATIONS FOR MEASUREMENT
1. Ensure the battery is correctly placed in the battery compartment.
2. Do not exceed the input limits shown below:
3. Inspect the test leads for damaged insulation or exposed metal. Check Test lead continuity. Damaged leads
should be replaced.
4. Select the proper function and range for your measurement
5. Check the input terminal position for red test lead depending on measurement ranges.
6. Either one of the test leads should be removed from the circuit under test when changing the test ranges.
7. To avoid electrical shock or damage to the meter Do not apply more then 500V between any terminal and earth
ground.
8. To avoid electrical shock, use caution when working above 60VDC or 25VAC rms. Such voltage poses a shock
hazard.
9. When measurement is completed switch off the power. Remove the battery when not used for extended
periods to avoid leakage problems.
10. Do not tamper with the circuitry to avoid damage.
11. Do not use or store the instrument in conditions of high temperature and high humidity.
5. METHOD OF MEASUREMENT
5.1 DCV & ACV MEASUREMENT
1. Set the Function range switch at the required position.
2. Connect black test lead to "COM" terminal and red test lead to the "V/OHM" input terminal.
3. Connect test leads to measuring point and read the display value. The polarity of the red lead connection will
be indicated at the same time as the voltage.
Note:
a. If the voltage to be tested is unknown beforehand, set the Function range switch to the highest range and
work down.
b. When only the figure "1" is displayed over range is being indicated and the function range switch has to be
set to a higher range.
c. Never try to measure voltage above 1000V! Although indication is possible, there is danger of damaging
the internal circuitry.
5.2 DCA & ACA MEASUREMENT
1. Connect the black test lead to the "COM" terminal and the red test lead to "A" terminal for a maximum of 0.5A
2. Set the function range switch at the required position.
3. Connect test leads to measuring points and read the display value. The polarity at the red test lead connection
will be indicated at the same time as the current.
Note:
a. If the current range is unknown beforehand, set the function range switch to the highest range and work
down.
b. When only the figure "1" is displayed, over range is being indicated and the function range switch has be
set to a higher range.
