As shown is an output voltage 22.5V DC side of the booster circuit that can be used instead of 22.5V DC battery, which use a multimeter in a 1.5V battery-powered operating current of 25mA output current is about 0.5mA high barrier for Multimeter wealthy enough. circuit composed of complementary multivibrator TR1 and TR2, its oscillation frequency is approximately 2KHz.T is the primary line of step-up transformer load up multivibrator secondary liters a high voltage output voltage of the pulse wave which the voltage after the rectifier diode D1 and the capacitor C2 becomes wave DC high voltage, and then after the resistor R3 and the voltage regulator tube ZD1 can output a stable high voltage.
