Easy to use counter for measuring time in microseconds. Particularly well suited for measurements made in conjunction with the microphone box. Includes 12 V AC plug-in power supply. The counting procedure is started via the Start input and
halted by means of the Stop input. Each new start causes the counter to automatically reset to zero. Both inputs respond to a rising edge and are equipped internally with pull-up resistors.
Measuring range 1 – 9999 µs
Resolution: 1 µs
Precision: Quartz precision
Internal resistance: 2.4 kΩ (Start input), 5.6 Ω (Stop input)
Switching edges for both inputs: Rising edge
Display: 4-digit LED
Connectors: 4-mm safety sockets
Power supply: 12 V AC, 500 mA plug-in power supply
Dimensions: 100 x 75 x 35 mm approx.
Weight: 400 g approx. including plug-in supply
