• The Ludlum Model 500 Pulse Generator (Pulser) provides the functions necessary for use in calibrating Ludlum instruments, as well as many other scaler/ratemeter instruments. 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

Pulse Rate from 1 – 9,900,000 cpm

• 0 mV – 5 V Total Pulse Amplitude Range
• Positive and Negative Pulse Polarity
• High Voltage Range from 0 – 2500 Volts
