DTL TTL CMOS Digital Logic Pulse Probe Analyzer Circuit Tester Test Pen 18V LP-1

Description

DTL TTL CMOS Digital Logic Pulse Probe Analyzer Circuit Tester Pen (DC 18V Max) LP-1
Features:
Diode : All not bright --- high-impedance
Diode : Red bright --- high value (1)
Diode : Green light --- low (0)
Diode : Orange bright --- pulse
The red alligator clip to the positive terminal of the test circuit, the black folder negative .
Attention to both ends of the voltage should not exceed 18V DC
Specification:
1, red alligator clip to the user to want to test the circuit positive, black alligator clip to the negative attention to two voltage should not exceed 18VDC
2, such as test DTL or TTL integrated circuits, test pen the upper part of the selector switch to the TTL side, such as testing of CMOS integrated circuit, the switch into the CMOS side and then test pen to test the probe contact point light-emitting diode in the test pen will indicate the status of the points are as follows:
A. Full LED not lit - the high-impedance
B. red shine diode does not shine - high-value
C. green light-emitting diode does not shine - low
D. Orange LED is not lit - Pulse
If the test pulse voltage transients, the first test described by the side of the selector switch to push'' the MEM'' side, such as test detected a pulse or voltage transients, long and bright orange light-emitting diode and the aforementioned original state both shows the pulse direction.
After use, the selector switch to the PULSE side reset
