Abstract
An indicating device for measuring instruments having a voltage-frequency converter for converting measurement signals expressed as voltage values into frequency signals with a frequency proportional to the voltage values, a counter for counting the frequencies of the frequency signals sent from the voltage-frequency converter and sending the counted number to an indicator for digitally indicating the measured values corresponding to the counted number. A switch is connected between the voltage-frequency converter and the counter, and a controller for holding the switch in the closed state only during a predetermined time is connected to the switch. Analog signals sent from the measuring device can be indicated digitally and the digital values indicated can be held by a simple, inexpensive and miniaturizable construction.
