OPERATION
CAUTION
The maximum input for current and voltage measuring are
500VAC, 500VDC and 250mA DC
MEASURING DC / AC VOLTAGE
If you are measuring a high-voltage, do not touch the testing
points.
1.- Connect the testing point to the right jacks (black “-“ and red
“+”).
2.- Set the dial to the VDC setting or VAC setting in accord to the
required voltage measure. If you are not sure about the voltage
level, set in 500V range.
3.- Connect the testing points to the equipment to be measured.
Make sure about the polarity.
MEASURING DC CURRENT
CAUTION:
Do not apply voltage to the testing points while the switch is
under current range.
1.- Connect the testing point to the right jacks.
2.- If you are not sure about the voltage level, set in 250mA
range.
3.- Open the circuit, then connect the black point to the negative
point of the circuit and the red to the positive point.
4.- Apply voltage to the circuit under measure and read the scale
VmA.
MEASURING RESISTANCE
Install a “AA” battery to measure the resistance.
CAUTION:
Do not apply voltage to the testing points while the switch is
under ohm range.
1.- Connect the testing point to the right jacks.
2.- Set the dial to the Ohm range (R X10 ó R X 1KOhm). Put the
testing points together and set the screw to place the measure
arrow to zero in the green side of the Ohm scale.
If you are measuring a high-voltage, do not touch the testing
points.
