thermocouple to the COM terminal.
3. Set the rotary switch to °C position.
4. The temperature will be displayed.
5. Maximum measurement of the temperature is
250°C / 482°F.
Continuity test (models RB-838 and RB-830BUZ
only)
1.
Connect the red test lead to the VΩmA terminal.
2. Connect the black test lead to the COM terminal.
3. Set the rotary switch to the
position.
4. Connect the test leads to a measured circuit. If
the resistance is lower than 30 Ω, the buzzer will
buzz.
hFE transistor test
1.
Set the rotary switch to the hFE position.
2. Determine the type of transistor (PNP or NPN)
and connect the emitter, base and collector to
proper sockets.
3. Approximate value of hFE will be displayed.
Generator function (model RB-830BUZ only)
1.
Set the rotary switch to position
.
2. Test signal 50 Hz will appear between terminals
VΩmA and COM. Input voltage is approx. 5 V
with impedance 50 KΩ.
