dick smith q-1024 multimeter

does anyone have a circuit?
or photo of component side circuit board?

If I recall it’s a soc thst drives the meter. About the only thing you can measure and change are the divider resistors and capacitors. The brains is buried in a blob.

not this one, it's an analogue meter.
2 resistors are damaged and another has been replaced.
Battery electrolyte has done a lot of damage and destroyed a trimmer.

I'm looking for exact values to repair

Then I have problem of how to recalibrate it... my thoughts are:

1) adjust meter rest to zero
2) apply 50uA and adjust meter bias to FSD
3) apply about 2A to 10A DC setting and adjust trimmer
4) apply about 2A to 10A AC setting and adjust trimmer

If its pure analogue ,as in just resistors in series parallel combinations it shouldn't be to hard to  trace out the  circuit diagram and calculate there value
