DESCRIPTION
The OEM335A is a complete digital voltmeter module in a
very compact package incorporating a dual-slope
analogue to digital converter, a 100mV reference with
200mV full scale input sensitivity.
The large sized LED makes the module easily readable
from distance away. Auto-zeroing is provided by the
circuit itself, so no zero adjustment is required. The
module also has input polarity and over-range indication.
