Using a Battery Tester using the meter and the case

I got a Battery Tester from Cousins. Costs just under £10, has a meter, switch and case. I thought that this be a good starting point, but it was found that this unit was too small to use in the end. A larger box and meter was used in the final version.

The switch is unsuitable.

The circuit of the tester follows:-

Resistor values are not given in the circuit diagram. They are as follows:-

R No					Value K (Measured)	Value
1	Grey	Green	Brown	Silver	0.749	850
2	Orange	Black	Brown	Silver	0.302	300
3	Orange	Black	Brown	Silver	0.302	300
4	Orange	Black	Brown	Silver	0.297	300
5	Yellow	Violet	Brown	Gold	0.470	470
6	White	Brown	Brown	Silver	0.916	910
7	Brown	Green	Red	Gold	1.485	1500
8	Brown	Orange	Red	Silver	1.334	1300
9	Brown	Red	Brown	Silver	119	121
10	Red	Black	Black	Gold	0.020	20
11	Brown	Black	Black	Silver	0.010	10
12	Blue	Grey	Brown	Gold	0.674	690

The parts that I thought would be used are the

Meter
Lead with Probes
Size of PCB 45 x 55 mm - strip-board replacement.
Case

All other parts are removed. There is sufficient depth for mounting switches along the side.

Second Results

This section highlights the changes that were made to the original design, including what happened when it was discovered that the PCB would not fit into the meter box when built.
