METER OPERATION

PRECAUTIONS AND PREPARATIONS FOR MEASUREMENT
1) Be sure the battery is connected to the battery snap and correctly placed in the battery compartment.
2) Before connecting the test leads to the circuit, be sure the range switch is set to the correct position.
3) Be sure that the test leads are connected to the correct meter terminals before connecting them to the
circuit.
4) Before changing the range switch, remove one of the test leads from the circuit.
5) Operate the instrument only in temperatures between 0 and 50
6) Pay careful attention to the maximum rated voltage of each range and terminal.
7) When finished making measurements, set the switch to OFF. Remove the battery when the instrument will
not be used for a long period of time.
8) Do not use or store the instrument in direct sunlight or at high temperature or humidity.

VOLTAGE MEASUREMENTS

1) Connect the black test lead to the "COM" terminal.
2) Connect the red test lead to the "V MA" terminal.
3) Set the range switch to the desired "V
the switch to the highest range.
4) Connect the leads across the points to be measured and read the display. If the range switch is too high,
reduce it until a satisfactory reading is obtained.
DCA MEASUREMENTS
HIGH CURRENTS (200mA to 10A)
1) Connect the black test lead to the "COM" terminal.
2) Connect the red test lead to the 10ADC terminal.
3) Set the range switch to the 10A
4) Open the circuit to be measured and connect the leads in series with the load to be measured.
5) Read the display. If the display read less than 200mA, follow the low current procedure below.
6) Turn off all of the power to the circuit being tested and discharge all of the capacitors before disconnecting
the test leads.
LOW CURRENTS (less than 200mA)
7) Connect the black test lead to the "COM" terminal.
8) Connect the red test lead to the V MA terminal.
9) Set the range switch to the desired A position. If the magnitude of the current is not known, set the switch
to the highest position.
10) Open the circuit to be measured and connect the leads in series with the load to be measured.
11) Read the display. If the range switch is too high, reduce it until a satisfactory reading is obtained.
12) Turn off all power to the circuit being tested and discharge all capacitors before disconnecting the test leads.
