The adjustable output pulse rate is displayed on a three-digit LED readout. Potentiometers (both coarse and fine controls) and a multiplier switch provide rates from 10 to 9.9 x 10\u003c\/span\u003e\u003csup\u003e6\u003c\/sup\u003e\u003cspan\u003e counts per minute (cpm). Pulse amplitude is controlled by a multiplier switch and a LO\/HI potentiometer, while pulse polarity is chosen by a selector switch. Amplitude may be varied between 0 and a negative or positive 5 volts; displayed on a four-digit LED readout.
