C-7 MEASURING TRANSISTOR hFE
1) Set rotary switch to "hFE".
2) Identify NPN or PNP, connect objects to the correspondent transistor jack.
3) LCD displays measuring value.
4) Measuring condition: Ib ≈ 10A, Vce ≈ 2.8V
MAINTENANCE:
The DMM51FSG is a highly precise electrical testing instrument, do not attempt to
change the circuit of your meter on your own. Take a note of the following points:
1) Do not input to DC Voltage above 1000V or AC above 750V RMS.
2) Do not input Voltage when the rotary switch is in Current Range, Ω and
3) Do not operate the meter if battery is not inside the meter or the casing is not
securely screwed together.
4) Disconnect the test leads and power off the meter before replacing the battery
and fuses.
5) To replace the battery, loosen the screws on the back cover and open the case.
Replace the exhausted battery with a new one of the same type.
The fuse rarely needs to be replaced and is usually blown as a result of
operator error. To replace the fuse, open the case as above and replace the
blown fuse with the ratings specified: F 2A/250V or F10A/250V.

(see Figure 2)
3) Set holster in a large angle on the table, tilt it up by all two parts of tilt stand
(see Figure 3).

1) Feed the front end of the strap through the
round metal loop of the meter
(see part 1 of the diagram).
