3B Scientific 1017333 Microsecond Counter 230V

Microsecond Counter (230 V, 50/60 Hz). 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 andhalted by means of the Stop input. Each start causes the counter to automatically reset to zero. Both inputs respond to a rising edge and are equipped internally with pull-up resistors.

Features:

• Measuring range 1 - 9999 ns
• Resolution: 1 ns
• Precision: Quartz precision
• Internal resistance: 2.4 kOhms (Start input), 5.6 Ohms (Stop input)
• Switching edges for both inputs: Rising edge
• Display: 4-digit Led
• Connectors: 4-mm safety sockets
