the higher range has to be selected.
( At the manual range mode, when the value scale to be measured is unknown beforehand, set the range
selector at the highest position. Application 1: Use 2V range to test the end state of the divider.
Take the high voltage line away from the cover of the divider, then connect with the iron.
The red test lead is connected with the low voltage connection pole of the divider, or with the end “ - ” of the
ignition winding; the black test leads is connected with the iron or the negative pole of the storage cell.
Open the ignition switch for a little while, the meter will indicate the value lower than
1V.
Directly measure the voltage of the end ’ s both sides, it indicates the end is good if the value is less than
0.2V.
Application 2: Use 2V range to check the leakage of the storage cell.
The black test lead is connected with the iron or the pole “ - ” , the red one is connected with all ends of the
storage cell.If some value is indicated on the meter, the leakage is existed. The storage cell should be
cleaned or replaced.
Application 3: Use 20V range to check the load capability of the storage cell.
The black test lead is connected with the iron or the negative pole of the storage cell; the red one with the
positive pole of the cell.
Open the switch of the front light, of the flashing, of the ignition and of the radio respectively.
The above process should be finished in 2 minutes.
D. Check the value less than 11.7V or not, if it is, then the storage cell should be recharged or replaced.
Application 4: Use 20V range to check the capability of the storage cell.
Take the high voltage line away from the cover of the divider and connect to the iron.
The black test lead is connected with the iron or the negative pole of the storage cell, and the red one
with its positive pole.
Start the engine and 15 seconds later check if the indicating value is more than 9.1V; if it is not correct,
the engine should be checked or the storage cell should be recharged or replaced.
Application 5: Check the cable of the power supply.
While the engine is started, measure the voltage of the both sides of the cable.
4.11 MEASURING AC VOLTAGE
WARNING
You can ’ t input the voltage which more than
600V rms AC, it ’ s possible to show higher
voltage, but it ’ s may destroy the inner circuit.
Pay attention not to get an electric shock when
measuring voltage.
4.11.1 Connect the black test lead to the COM jack and the red test lead to the INPUT jack.
4.11.2 Set the transform switch at the V range position.
4.11.3 Put down the "FUNC." to enter the AC measurement. Auto range or manual range can be
transformed by putting the “ RANGE ” .
4.11.4 Connect test leads across the source or load under measurement.
4.11.5 You can get reading from LCD.
