Push once to hold the current reading on the display; push again to continue normal operation. Push for more than 2 seconds to enter the relative mode. The product will store the present reading as a reference for subsequent readings. The display is zeroed, and the stored reading is subtracted from all subsequent readings. Longpush again to exit the relative mode.

Push this button to toggle between modes of DCV, ACV, and NCV.

testing

Push this button to toggle between testing modes of DCmV ( 99.99mV), ACmV(
99.99mV), and Temperature.

Push this button to toggle between testing modes of Resistance, Diode/Continuity, and
Capacitance.

Push this button once to enter the manual range mode. In manual range mode, each push increases the range; when the highest range is reached, the next push will lead to the lowest range. To exit the manual range mode, push the button for more than 2 seconds.

Measurements Instruction
Measure AC/DC Voltage 1. Connect the black test lead to the COM Terminal
and the red lead to the VHz Terminal. 2. To measure voltage under 99.99mV, push ,
push once to measure DCmV, push twice to measure ACmV. To measure voltage higher than 99.99mV, push , push once to measure DCV, push twice to measure ACV. 3. Touch the probes to the correct test points of the circuit to measure the voltage. 4. Read the measured voltage on the display.
Do not measure voltage that exceeds the extremes as indicated in the Specifications. Do not touch high voltage circuit during measurements.
Measure AC/DC Current 1. Connect the black test lead to the COM Terminal
and the red lead to the AmA Terminal or the A Terminal (choose based on the value of the current to be measured); if the previous setting was continuity/diode, push any of the three rectangle buttons on the left once.

2. Push to toggle between DCA and ACA. 3. Break the circuit path to be measured, connect
the test leads across the break and apply power. 4. Read the measured current on the display.
Do not measure current that exceeds the extremes as indicated in the Specifications. Use the AmA Terminal when you are measuring an unknown current. Then switch to the A Terminal if necessary. Do not input voltage at this setting.
Measure Resistance 1. Connect the black test lead to the COM Terminal
and the test lead to the VHz Terminal. 2. Push once to enter the Resistance Mode. 3. Touch the probes to the desired test points of
