PROGRAMMABLE AMP. HOUR METER MODEL 810AH

INTRODUCTION:

This micro-controller based programmable Amp-Hour Meter is designed to integrate and display DC current flowing respect to time. It becomes a measure of the total current energy.

A preset limit of this integrated current can be pre-programmed and when the limit is reached, a relay is switched ON to trigger an alarm. A 6 digit display for Ampere Hour and a 4 digit display for Current is provided.

In addition, an internal limit of 10.5V is preset so that a 12V Battery can be tested for its A-H. As soon as the 12V battery discharges to a voltage below10.5V the Amp-Hour meter stops automatically.

The instrument reads current also. For different ranges, the equipment can be user-programmed for different shunt resistances.

Features

• Current Integrated Display
• 4 DIG AMP-HOUR (Selectable: AH , 0.1 AH, AMin & 0.1 AMin)
• Presetable Limit for Amp-Hour with Relay Out,
• 6 Digit Totalizer AH Stored in EEPROM & Front Resettable
• Displays Current in Amps
• Lockable Scale Factor -CAL- for Various Shunts
• Signal Input in mV from Current Shunt of 75mV/Amp
• Application in Constant Thickness Electroplating which is Proportional to Preset AH Limit, irrespective of Voltage/ Current Variation.
• Simultaneous Input for mV(from Current Shunt) and Battery Voltage, to measure the AH of a chargeable Battery when Voltage falls to Factory-Settable Limit( usually 10.5V for 12V Batt)
