This means that disassembly and cover removals not required for adjustment and calibration with few exceptions, covered later. I have an HPA at home.

So I got idea to prevent running this procedure for intermediate testing. The Reed Relay Multiplexer can close a relay and make a measurement at a maximum rate of channels per second.

This stable 2V level supplied to voltage-current converter around Ua,Q with current setting by resistor R Worth to note, that this operational amplifier must be stable with both high and low gains, and as we will see later, most troublesome range for stability is 3 V.

Urge to attach something generating light to aid readout visibility is very hard to resist. On alternating voltage, A is much weaker than older A. Please provide the requested information to receive an estimated shipping cost.
