programmable amp-hour meter
model 800ah

features

 amp-hr/amp-min indicator/controller for

        o electroplating thickness control

        o testing battery amp-hr

 shunt calibration programmable

 stores cumulative amp-hour

 instantaneous current display

 settable limit for amp-hr/min

 front membrane switches for easy operation

 non-volatile memory for storing settings, hence no battery required
