More information
Time counters count the time in hours with an accuracy of two
decimal places (hundredths of an hour). The pulse counter sums
up the number of pulses, e.g. the making operations of devices.
A power supply is required at terminals 1 and 3 of the electronic
counters so that the device can constantly display the measured
values. Once terminal 3 is supplied with voltage (for DC "+"), the
counting procedure starts. If terminal 4 is supplied short-time
with voltage (for DC "+"), the counter is reset.
In the case of electronic counters, the counting result is saved
indefinitely in the event of a power failure (EEPROM). On recovery
of the power, the counting is continued from the saved value.
As well as a modern design, the electronic counter has a 7-digit
LCD, which can be reset electrically or manually.
