Too many old style heavy gauge wire ammeters. When the Cobalt inductive pickup is properly clamped over a wire in the circuit subject to + or - current flow, does the Cobalt amp gauge display the + or - in addition to the digital value? How displayed?

Asked by: Anonymous
Thank you for your question. No, it will not display the +/- in addition to the displayed digital value.

This amp gauge can handle 250 amps. So, could it be used on the positive battery wire to measure the total current in the entire electrical system in a vehicle? Or perhaps on the alternator charging wire to know the current draw on the alternator?

Asked by: AdamL
Thank you for your question. Yes, you could. As long as the lead for you are measuring can fit through the inductive pickup, it will work. You could certainly use it at the battery or alternator as you wanted to, as long as you can fit the wires in the inductive pickup.

is there a way i can calibrate the housing the wire travels thru? im working with 8 AWG wire and im getting about a 3amp difference from my calibrated tester. i see 2 dials on the unit and i figure those can calibrate or alter the calibration.

Asked by: Mike florida man
Hi Mike, thank you for reaching out to us. The transducer is calibrated and set at the factory and we do not recommend attempting any adjustments.
