MAXIMUM OPEN CIRCUIT VOLTAGE: 3.2V.
OVERLOAD PROTECTION: 15 seconds maximum
220Vrms.
OPERATING INSTRUCTIONS
DC & AC VOLTAGE MEASUREMENT
1. Connect red test lead to "VΩmA" jack, Black lead to
"COM" jack.
2. Set RANGE switch to desired VOLTAGE position, if
the voltage to be measured is not known beforehand, set
switch to the highest
range and reduce it until a satisfactory reading is
obtained.
3. Connect test leads to device or circuit being measured.
4. Turn the circuit or device that's being powered's power
on, its voltage value will appear on the Digital Display
along with the voltage polarity.
DC CURRENT MEASUREMENT
1. Red lead to "VΩmA". Black lead to "COM" (for
measurements between 200mA and 10A connect the red
lead to "10A" inserting it completely into the jack).
2. Set RANGE switch to desired DCA position.
