2. INSTALLATION

Back Panel

General

a)The standard version is for bench-top use. Retractable legs can be extended to provide a convenient viewing angle.

b)The optional version permits the installation of the DP97 into a suitable panel cut out.

Supply Connection

Primary power is provided by the internal, rechargeable sealed lead-acid battery which provides up to 12 hours operation from a full charge. The external supply adapter for recharging and also allows operation directly from a 220/240V 50/60Hz supply (or 110V 50/60Hz to special order). The output lead with its fitted connector is connected to the appropriate rear panel mating connector.

Internal battery power can provide operation for up to 12 hours from full charge. Low battery charge state is indicated by “bAtt” on the display.

Input Connections – Sensors

Platinum Resistance Thermometer(s) (Pt100) must be fitted with a high quality D-plug and connected to INPUT A and/or INPUT B as required. A 3 OR 4 wire configuration can be used but they are connected differently as shown. The DP97 will automatically sense which configuration is employed.

Special care must be taken when connecting 3 wire resistance thermometer terminations to the connector pins. A good crimp must be achieved to avoid Ohmic contacts, which would result in reading errors. Only use good quality connectors with gold contact mate rial; the OMEGA D type is recommended.
