GS 5 THRESHOLD PROBLEM

[kt315]

linear stabilizer does not give 12V from 12V. must be some voltage reserve. 2V is minimal value. in Elite the one gives 10V output.
so 12V of battery will be very critical. ML holder are 10 pcs 1.3V Nicad gives 13V but if you put 8 pcs 1.2V nimh you get only 9.6V. you see - NOT 8, but 10 pcs.
that why you can not directly use nimh battery in Elite/gt using a holder for alkaline battery.

Eric lost hard disc crashed and all info on it. so we do not have detail voltage list in all test points and the schematic on GS5.
unperspective case.

Hi kt315...i remember some years ago when i had a minelab elite the same problem would happen when the voltage level dropped to a certain level and the threshold would then go too loud

Link to EXACT Schematic you are using please?

Hello waltr....i have no link....its a GS 5 issue 2...maybe some other pulse detectors have similar problems.

i have a problem with a GS 5....once i adjust the threshold to correct level then ok...but once the battery voltage drops below 13 volts then the threshold go's a bit louder and also below 13 volts i cannot zero the threshold into silence...could anyone offer any advice on this problem.
