Description:

Item type: tool

Package includes:

1 * SR meter
1 set Case

Notes:

Can detect bipolar transistor and MOS transistor protection diode.
Measure the threshold voltage and grid capacitance of gate MOS FET.
Can simultaneously measure two resistances and resistance symbol display.Shown on the right, the decimal value is 4.The resistance symbols on both sides indicate pin Numbers.So you can measure potentiometers.If the potentiometer wiper is not shifted to the limit position, we can distinguish between the middle and both ends of the pin.
Resistance measurement resolution is 0.1 ohm, and 50M ohm can be measured.
Measurable capacitance can be used to measure the capacitance of 30pf-100mf with resolution of 1pF.
The ESR value of equivalent series resistance can be measured simultaneously for capacitors over 2uF.These two display decimal values at a resolution of 0.01 ohms.
Can be in the correct order and diode symbol display two diodes, and give diode forward voltage.
LED is detected to have higher forward voltage of diode.The combination of leds is identified as two diodes.
Eeverse breakdown voltage less than 4.5V zener diode can be recognized.
Can measure the reverse capacitance of a single diode.If the bipolar transistor is connected to the base of the pin and to the collector or emitter, it can measure the reverse capacitance of the collector or emitter junction.
The structure shown in figure 18 can be obtained by measuring a single rectifier bridge connection.

1-2cm error might exist due to manual measurements, please kindly understand. The colors deviation might differ due to different monitor settings.
