DPM 702S
An ultra-low profile LCD meter using advanced components and construction techniques to provide an unrivaled combination of dual channel voltage
measurements and low cost. This product is ideal for those applications where "matched" readings are required, e.g.: voltage and current, temperature and
humidity, etc. Both measurement inputs share a common ground line, thereby reducing the number of connections to a minimum. The very low current
consumption results in a long battery life and makes it especially suitable for portable equipment. A low battery warning circuit is fitted as standard. The 10-
way pin header can be replaced by screw terminal blocks on request. Contact your nearest Lascar Sales Office for further details.
SCALING
The full scale reading (F.S.R.) of each measurement
channel may be altered by the addition of two resistors
Ra and Rb per channel- see
