Ammeter LCD.Digital +/- 0-2A.DC Auto power off.
Measures from 0.000 (1 milliamp) to 1.999 amps.
Powered by a standard 9V battery, easy to change when required.
A "LO BATT" alarm displays well before the battery must be replaced and accuracy is not affected.
Power turns off automatically after 20 minutes to protect against forgetful users. One touch of the only button restores the display.
If the 2 amp DC rating is exceeded, a red LED illuminates as a reminder but there is no chance of damage.
There are no knobs, switches or fuses to replace. A perfect ammeter for the classroom and not much more expensive than a fragile analogue meter.
