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