-trying torque now.as a automotive technician/fitter,and ex rac patrol- one VERY USEFULL dial that i reckon would be great to include on TORQUE- would be a BATTERY VOLTAGE DIAL.so that battery voltage/and alternator voltage can be measured.it would be pretty easy to include this i think,andit could establish wether your battery is weakening (by switching on lights while engine off) and checking alternator output voltage-with different loads on (lights,fan,etc)against the voltage output-in different states.so many many many times i see breakdowns,and mis-diagnosed battery/charging faults-that could easily be pre-empted by this.

I do not find a battery voltages display.
