SERIES 200C
The Series 200C is a 20000 count digital panel voltmeter with options for Analog outputs or TTL compatible three state BCD outputs. The unit is housed in a heavy duty all aluminum case with a big (.56") bright LED display. There are two standard ranges available but the unit can be easily rescaled in the field with solderless jumpers. Upon request, DCI will set up your special scale prior to shipment, for a nominal charge.
