The counter is equipped with semiconductor counting circuitry. When the counter counts up to a preset number, its output circuit sends a signal.
A magnet is magnetized and demagnetized to drive the dial and count up numbers.
The voltage is applied to start the counter.
This is a voltage or current signal sent at intermittent time intervals.
Pulses are used to count up and down.
This happens if the number of pulses does not correspond to the number of counts.
This unit of counting speed is used to give the number of counts per second. This unit of counting speed is used to give the number of counts per second.
This is the ratio of ON time (Ta) to OFF time (Tb).
Suppose that the counter is operated with an input pulse of a make ratio of 1. The highest counting speed is the peak of a range in which the output circuit can send signals without mis-counting. The speed is expressed in units of Hz (cps: counts per second).
Counting continues beyond a preset number.
When counting is up, the counter display resets to zero and counting restarts.
Numbers are counted down one by one from a preset number.
Numbers are counted up one by one from zero.
Numbers are counted up or down depending on input conditions.
This signal is used to keep the counter from counting.
When a preset number is reached, the output circuit sends a signal.
The output is held until a reset signal is sent.
This output has a specified width of time.
The counting process, display and output sections are all brought back to the initial status.
The operating voltage is turned off to reset the counter.
The counter is manually reset.
A signal is sent from a remote point to the reset terminal so as to reset the counter.
When counting is up, internal circuitry is activated to automatically reset the counter.
This is the time during which the power is off so as to reset the counter or during which an external (manual) reset signal is sent.
This is the time from the moment a reset signal is sent to the instant the counter is ready to start counting again.
Counting data up until the operating voltage is turned off can be stored in memory. When the power is reactivated, the data can be reproduced.
The strength against power voltage surge is determined by applying a singlepole full-wave voltage (several hundred to several thousand volt wave for ±(1.2 × 50) μs) acrosss the control power terminals.
This is the strength against external noise. Relay noise tests, noise simulator tests, etc. are conducted.
