1. LCD Display
2. Hold button
3. Function switch
4. COM jack
5. 10A jack
6. Positive jack
Note: Tilt stand and battery
access is on the rear of unit.
Operating Instructions
Note: If "H" and a blank screen appear when the meter is turned on the HOLD feature is active.
Press the HOLD button to exit the HOLD mode.
AC or DC Voltage Measurements
1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana
plug into the positive V jack.
2. Turn the rotary switch to the highest VAC or VDC position.
3. Touch the test probes to the circuit under test and read the voltage on the display.
4. Reset the function switch to successively lower positions to obtain a higher resolution reading. If
the polarity is reversed (DC voltage only), the display will show (‐) minus before the value.
DC Current Measurements
CAUTION: Do not make current measurements on the 10A scale for longer than 15 seconds
followed by a 15 minute cool down period. Exceeding 15 seconds may cause damage to the
meter and/or the test leads.
1. Insert the black test lead banana plug into the negative COM jack.
2. For current measurements up to 200mA DC, set the function switch to the 200mA DC position
and insert the red test lead banana plug into the V//mA jack.
3. For current measurements up to 10A DC, set the function switch to the 10A DC range and insert
the red test lead banana plug into the 10A jack.
4. Remove power from the circuit under test, then open up the circuit at the point where you wish
to measure current.
5. Touch the black test probe tip to the negative side of the circuit.
Touch the red test probe tip to the positive side of the circuit.
6. Apply power to the circuit.
7. Read the current in the display.
