Transistor Hfe Measurement; Temperature Measurement; Audible Continuity Test; Battery Test - MAURER 51924 Manual De Usuario

4. The forward voltage drop in mV will be displayed. If the diode is reversed,
figure "1" will be shown.

TRANSISTOR hFE MEASUREMENT

1. RANGE switch to the hFE position.
2. Determine whether the transistor is PNP of NPN type and locate the
Emitter, Base and Collector leads. Insert the leads into the proper holes of
the hFE Socket on the front panel.
3. The meter will display the approximate hFE value at the condition of base
current 10µA and V

TEMPERATURE MEASUREMENT

1. RANGE switch to TEMP position, it will display room temperature in ℃
value.
2. Connect the K-type thermoelectric couple to "VΩmA" and "COM" jacks.
3. The display will read Temperature value ℃.
NOTE: The TP-01 K-type thermocouple Max. Operating temperature of Probe:
250˚C/482˚F (300˚C/572˚F short-term). The sensor supplied with the
instrument is an ultra fast response naked bead thermocouple suitable for
many general purpose applications.

AUDIBLE CONTINUITY TEST

1. Red lead to "VΩmA", Black lead to "COM".
2. RANGE switch to " " position.
3. Connect test leads to two points of circuit to be tested. If the resistance is
lower then 30Ω±20Ω, the buzzer will sound.
TEST SIGNAL USE
1. RANGE switch to "
2. A test signal (50Hz) appears between "VΩmA" and "COM" jack, the output
voltage is approx 5V p-p with 50KΩ impedance.
NOTE: OVERLOAD PROTECTION: 15 seconds maximum 220Vrms.

BATTERY TEST

1. Set the FUNCTION switch to 9V or 1.5V.
2. Connect the test lead to Battery.
3. The display value is voltage.
2.8V.
