Large moving coil panel micro-ammeters having a 76mm (3in.) scale length. Calibrated 0-50 or 0100, but front plastic cover unclips to facilitate fitting different scales to your design. (Please note that we do not stock spare scales.) Dimensions: 110 x 82 x 46mm deep. Internal resistance 50╡A: 4300 ; 100╡A: 3750. To convert this meter to read larger currents use the following formula: |
| FSD required (in amps) - (y x 10-6) = R |
| To convert this meter to a voltmeter use the following formula: |
|
Full scale voltage required (V) |
| where R is the resistance required directly across the meter; R2 is the resistance required in series with either lead; x is 0.375 y is 100 and r is 3750. |
