Test probe PH-5H
The tester can be used to inspect integrated circuit printed circuit boards: two 4.7KΩ resistors and the transistors connected to them act to block current flow through the operator amplifier before the probe is turned on. A Zener diode is placed in series with the op amp output to eliminate audio oscillations before the op amp's positive output reaches a sufficient amplitude.
