•
Remove power from the circuit under test then apply the black test probe to the negative
and the red probe to the positive open circuit and read off the value on the display.
Power and current measurement of two wire loop
•
Insert the black test lead into the negative (COM) jack and the red test lead into the
positive (mV-mA) jack.
•
Set the function switch to power (Power/mA) position.
•
Press the 0-19.9mA button to set the 0.01mA display resolution (max display is
19.99mA) or press the 0-24mA button to set the 0.1mA display resolution.
•
Apply the black test probe to the negative and the red probe to the positive in series with
the load in which the current is to be measured and read off the value on the display.
DC mV Source
•
Insert the black test lead into the negative (COM) jack and the red test lead into the
positive (mV-mA) jack.
•
Set the function switch to voltage (mV Source) position.
•
Adjust the calibration rotary control (CAL ADJUST) to generate the voltage (mV) output.
MAINTENANCE
Cleaning the casing
•
Wipe using a damp cloth or sponge. Do not use solvents as these may damage the casing.
BATTERY REPLACEMENT
•
Disconnect the test leads from the meter before opening the battery cover.
•
When LCD display show the " BAT " marker, it is necessary to replace the battery.
However, measurement may still be made after low battery indicator appears although
accuracy cannot be guaranteed.
•
Remove the screw and lift off the battery cover away from the instrument and remove
the battery.
•
Replace with a new 9V battery and refit the cover and tighten the screw.
