Panel Meter

Illustration of the display, showing the value 0.314

A digital panel meters is part of The Analog Thing. The striking display is located in the lower right on the upper board and a central part of the board

Usage

The Panel Meter is an instrument which is used as voltmeter in several cases and depends on the switch mode setting (operation mode). In mode COEFF the coefficients can be setup with the eight potentiometers while the COEFFICIENT switch chooses one of the eight COEFFs which value is displayed on the voltmeter. This allows an easy setup.

In mode REP or REPF the current OP TIME value is shown or can be changed with control via the voltmeter. In all other positions except OFF the voltmeter shows a voltage (or value) which can be feeded into the OUT jack U on the front panel with a patch cable to a specific input or output.

Technical details

• The display is analog but digital, in order to be cheap (price around 5 Euro). The instrument is a PM438 and normally shows the voltage on the output channel U.
• The instrument can show bipolar voltages, i.e. it can show values in the whole logic level domain of ±1.
• Actually the voltmeter shows the voltage (max ±10V) just divided by 10. Values are normally always smaller then +1 (or bigger then -1, respectively). The leading zero (The 0 in 0.123) is omitted in the display, so numbers start with a dot.
