ORION EM G

DIGITAL FREQUENCY· AND TIME METERS
EMG-1645 TR-5250 Digital Frequency- and Time Meter
The instrument is designed primarily for laboratory purpos~s.
for the measurement of frequency, period time, average period
time, pulse width, time interval and frequency ratio. It can al~o
be used the totalizing count. The measured result appears on
seven in-line numerical indicator tubes.
