Black， negative test lead.
(+) Jack: Plug-in connector at the lower right on the panel for
Red， positive test lead.
OPERATING INSTRUCTIONS
CAUTION
When making voltage or current measurements， develop the
habit of turning off all power to the circuit under test. Connect
the test leads at the desired points in the circuit， and then turn
on the power while taking readings. Turn off the power before
disconnecting the test leads from the circuit.
INTERNAL BATTERY CHECK
To check the battery condition， insert the black test lead into
the (-) jack. Set the range switch to the R X1 range position and
short the ends of the two sides of the test leads. If the pointer
can not be brought to the zero mark， replace the 1.5V cells or
9V cell. (See battery replacement.)
BEFORE OPERATING
1. Set the range switch to the proper position before making
any measurement.
2. Never apply more voltage or current than the rated value in
every position.
3. When the voltage or current to be measured it not known，
always start with the highest range.
4. If meter indication is in the lower half of the scale and falls
within the range of a lower scale， reset selector switch to the
lower range for greatest accuracy.
5. If the meter won't work at all， check the fuse located on the
PCB. If it's blown， replace it. (See fuse replacement.)
6. Avoid placing the meter where extreme shock or continuous
vibration is encountered and do not store in excessively hot
