cx101 lcd panel meter quotation

I"d like to build a constant current load like the one in Dave"s video (#102) and am stymied by the panel meter he uses. It"s a CX101 (presumably the BG version that works with common ground). But this thing doesn"t seem to exist anywhere. I found one site that claims to sell them, but it"s not a site I know (https://www.circuitspecialists.com/lcd-panel-meter-cx101bg.html). Is this thing discontinued? If so, are there alternatives that would do the job?

I can"t seem to find a reasonably priced panel meter that"ll read in the appropriate range (from 0 to "less than 2V"). All the stuff on digikey seems to either have a non-zero low-voltage or it seems to be on the expensive side (in the $30 range and up).

This particular panel meter is reliable and of reasonable quality. Best of all is it’s low cost. It is a 3 1/2 digit meter with decent accuracy for the price.

There are a number of flavors for this meter and choice is application dependant. The CX101A & CX101B are designed to be used with an independent (isolated) ground. The signal being measured does not share a common ground with the supply voltage for the panel meter.

This Tube Tester has Anode Current measurement Ranges of 0-3, 0-10, 0-30, 0-100 mA, and the meter scale is marked 0-30 and 0-100 units, and the scale is marked with �mA and �=�.

The M310B meter shunts, 1.01, 3.57, 12.57, 100 ohms, are correct values for a 1.0 mA 50 ohm meter movement to give ranges of Anode Current of 0-1.5, 0-5, 0-15, 0-50 mA Continuous DC current.

But ..., the M310B has a 0.9 mA 50 ohm meter movement installed, and with the original shunts, this gives FSD values of 1.35, 4.5, 13.5, and 45 mA for Continuous DC current.

The M310 panel moving coil meter has been confirmed as being 0.9 mA coil FSD, and 15.5 ohms coil resistance, padded out with series resistor R10 of 34.5 ohms, (R9 on some M310B ccts) to be 0.9 mA with total resistance of 50 ohms.

Metrix say in the Tech Notes that when replacing a meter, the resistor must also be replaced. It also says that R10 is normally in the range of 40-50 ohms.

This means that with half wave sine DC whose peak current value is the FSD, the meter will deflect to the �mean� or 0.318 of these Continuous DC FSDs giving �FSD indications� of 0.43 mA, 1.43 mA, 4.30 mA, and 14.3 mA respectively.

If the G1 bias is adjusted to obtain a peak tube current of 100 mA on a CRO, then the M310 meter needle �indicates� approx �70 mA�, and a VOM measures a mean of 31 mA.

Again, the M310 panel moving coil meter is confirmed as being 0.9 mA FSD and 15.5 ohms, padded out with series R10 of 34.5 ohms, (R9 on some circuits) to be 0.9 mA with total resistance of 50 ohms.

To reiterate, if the original shunts are used with the 0.9 mA 50 ohm meter, then the actual current ranges with Continuous DC are 0-1.35, 0-4.5, 0-13.5, 0-45 mA.

If you are testing a tube, and you switch the unit to the �0-100mA� Anode Current range, and you have half scale of indicated anode current, ie �50 mA indicated�, the meter needle with half wave sine DC has deflected to 22.5 mA mean (half of 45 mA real FSD).

I can understand that if the cathode emission capability of a tube can supply a required peak current, and thereby it can supply a certain mean current, as read on the panel meter to establish if the tube is �good�.

I can confirm that the tube anode voltages are as indicated on the M310B front panel are in fact RMS voltages, ie 250 V measures 250V RMS full wave AC.
