Electronical running hour counter
| Application | |
| The instrument measures the running hours of vehicles. | |
| Description | |
 The
time base forming part of the counter is a high-precision oscillator
of quartz control, which will be devided to the desired frequency
by a digital frequency divider built into an IC. This divider actuates
- through a suitable aplifier stage – the mechanical counter
driven by the stepping motor. The counter cannot be reset to zero,
The function of the instrument is indicated by the flashing of the
LED, which can be seen on the dial. The instrument is a counting device
built into an internal-illumination metall case coated against corrosion. |
