OPERATION
DC & AC VOLTAGE MEASUREMENT
•
Connect red test lead to "VΩmA" jack, Black lead to "COM" jack.
•
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 satisfactory reading is obtained.
•
Connect test leads to device or circuit being measured.
•
Turn on power of the device or circuit being measured voltage value will
appear on Digital Display along with the voltage polarity.
DC CURRENT MEASUREMENT
•
Red lead to "VΩmA". Black lead to "COM" (for measurements between 200mA
and 5A connect red lead to "5A" jack with fully depressed).
•
Set RANGE switches to desired DCA position.
•
Open the circuit to be measured, and connect test leads IN SERIES with the
load in with current is to measure.
•
Read current value on Digital Display.
•
Additionally, "5A" function is designed for intermittent use only. Maximum
contact time of the test leads with the circuit is 10 seconds, with a minimum
intermission time of 15 minutes between tests.
