Measuring Ac Voltage; Diode And Continuity - Probuilder 89177 Manual De Instrucciones

Measuring AC Voltage

1) Set the function switch to V or V range.
The LCD displays "AUTO AC" or " AUTO
DC".
2) Connect the test leads across the source
or load to be measured.
3) Read the LCD display. The polarity of the
RED lead connection will be indicated
when making a DC measurement.
4) If the AC voltage is tested, the LCD shows
the value of the AC voltage.
5) Press the Hz% key to select the
measurement of frequency or duty cycle.
Note:
1. Be careful to avoid electric shocks
when measuring high voltages.
After completing the measurement,
disconnect the meter lead from the
circuit being tested.
2. Pure DC voltage does not have a
frequency or duty cycle, so the operation
is invalid for DC voltage tests.

Diode and continuity

Range
Precision:
±1.2% ± 8 D
Overload Protection: 250V DC/AC rms
±1.0% ± 8 D
For continuity test: When the resistance
±1.0% ± 8 D
is between 30Ω and 100Ω, the buzzer
±1.0% ± 8 D
may sound or may not sound. When the
resistance is more than 100Ω, the buzzer
±1.2% ± 8 D
won't sound.
Resolution Precision:
0,1 Ω ±1.2% + 8 D
1 Ω ±1.2% + 5 D
10 Ω ±1.2% + 5 D
100 Ω ±1.2% + 5 D
1 kΩ ±1.2% + 5 D
10 kΩ ±1.5% + 5 D
Introduction Remark
The approximate Open circuit
forward voltage voltage:
drop will be about 1.5V
displayed
The built-in Open circuit
buzzer will voltage:
sound if the about 0.5V
resistance is less
than about 30Ω.
