For measurement of times, frequencies and pulses, optimal protection against incorrect usage, and many measuring and triggering possibilities.
Four different functions
- Time measurement: Trigger signals external to the instrument (light barriers, microphones etc.) control the digital counter over the “Start/Stop” and “Stop” sockets, 6 different triggering possibilities, intermediate time display
- Manual stopwatch: The “Start”, “Stop”, “Reset” and “Display” buttons allow the use of the digital counter as an additive stopwatch with intermediate time display.
- Frequency measurement: With automatic, microprocessor controlled measuring time minimization.
- Pulse counting/pulse rate determination (for radioactivity measurements): The quantities measuring time and pulse rate are ready for display alongside the pulse count. With a press on the button during a measurement, the actual pulse rate can be frozen with the recording continuing.
• All measuring ranges and measuring modes can be selected manually, automatic or manual changes of measuring range
• LED indication of operating status
• BNC socket for connection of a Geiger tube, with 500 V bias voltage
• Integrated loudspeaker, which can be switched off
