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.
