3.
4.
Connect the red test lead to “V. Ω. mA” jack and black
test lead to the “COM” jack. (The polarity of red lead is
positive “+”.)
Set the rotary switch at desired ”Ω” range position.
Connect test leads across the resistor to be measured
and read LCD display.
If the resistance being measured is connected to a
circuit，turn off power and discharge all capacitors before
applying test probes.
AUDIBLE CONTINUITY TEST

3.
Connect red test lead to “V.Ω.mA”, black test lead to
“COM”.
Set range switch to “ ” position.
Connect test leads to two points of circuit to be tested. If
continuity exists, built-in buzzer will sound.
MEASURING TEMPERATURE
1.
2.
3.
If the meter is the ℃ function, set the rotary switch at
℃. Position. If it is the °F function, set the rotary switch
at °F Position. The LCD display will show the current
environment temperature.
Connect the red lead of“ K ” type thermocouple into
the “V.Ω.mA” jack and the black lead of“ K ” type
thermocouple into the “COM” jack.
Read temperature value on the LCD display.
WARNING:
To avoid electric shock, be sure the thermocouple has been
removed before changing to another function measurement.
BATTERY & FUSE REPLACEMENT
If “ ”appears on display, it indicates that the battery should
be replaced.
Fuse rarely need replacement and blow almost always as a
result of operator’s error.
To replace battery & fuse (200mA/250V) remove the 2 screws
