TRANSISTOR TEST
1. Set the rotary switch at "hFE" position.
. Determine whether the transistor under testing is NPN or PNP
and locate the emitter base and collector leads. Insert the leads
into proper holes of the hFE socket on the front panel.
. Read the approximate hFE value at the test condition of base
current 10µA and Vce 3V.
NOTE:
To avoid electrical shock, remove test leads from measurement
circuits before testing a transistor.
AUDIBLE CONTINUITY TEST
1. Connect red test lead to "V.Ω.mA", black test lead to “COM”.
2. Set range switch to " " position.
. Connect test leads to two points of circuit to be tested. If conti-
nuity exists, built-in buzzer will sound.
MEASURING TEMPERATURE
1. If the meter is the ºC function, set the rotary switch at ºC. Posi-
tion. If it is the ºF function, set the rotary switch at ºF Position.
The LCD display will show the current environment tempera-
ture.
2. 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.
