  • Page 3: Battery Charging

    The charger supplied with the DP6 is of a plug-top style and models are available for most countries. It is a two-stage charger providing bulk charge for fully discharged batteries, automatically switching to trickle charge state to maintain the battery at full charge level.
  • Page 4: Case Design

    CASE DESIGN The DP6 is housed in a high impact plastic case with a sealed switch membrane for the front panel. The rear of the instrument incorporates two low thermal emf copper terminals for connection; a five-pin DIN socket for the RS232 connection, and a 2.5 mm.

    Full cold junction compensation is incorporated with the flexibility of switching on or off or entering a numerical value. The DP6 provides for variable rate ramping via the up/down keypad of the simulated values, or set values may be entered directly from the keyboard.

    After you have made the final parameter selection, press SEL to remove the flashing cursor and return to the fixed display which will now show the chosen set-up. DP6 Handbook.doc Page 6 Iss. 2/2001...
  • Page 7: Right Hand Menu Display

    In some cases, a third option menu will appear giving more choice of configuration. EXAMPLE: To configure the DP6 in SOURCE mode for a type K thermocouple with cold junction OFF, proceed as follows: Press SEL - measure/source flashes...

    Press SEL to CJ=+000.0°C remove flashing cursor. The DP6 is now configured to SOURCE Deg. C for a type K thermocouple with a cold junction switched OFF. Follow the above principle to change any parameters. Press SEL to highlight the function you wish to change.

    It can display the temperature in degrees Centigrade, Fahrenheit or absolute Kelvin Connect the thermocouple to the terminals at the rear of the DP6 (ensure the correct polarity). The red-based terminal is the positive and all-black terminal is the negative connection.

    The purpose of simulating thermocouple outputs is to calibrate temperature sensing devices such as indicators, recorders, controllers and data loggers. The DP6 will simulate temperature in degrees C, F or K. The simulated value can be switched between these units and the displayed value changes to show the same output value scaled in the new units.

    DP6 terminals using thermocouple wire or thermocouple compensating cable. In this configuration any difference in temperature between the test instrument and the DP6 will be compensated for by the emf generated by the difference in temperature between the two end of the connecting wire.

    The DP6 has 10 memories for each thermocouple type and mV range, making a total of 130 memories in total. To store a configuration, first set the DP6 to the complete configuration that you wish to store, including measure/source mode, cold junction configuration, units and value if in source mode.

    DP6 terminals, note the reading on the DVM. The right hand display will indicate the value that the DP6 should be injecting. If the DVM value is within the required tolerance, then press OK. If the value is outside the tolerance, then press CAL.
  • Page 14: Storage

    We expect the DP6 to give long and trouble-free service but, as with everything, there will come a time when you will want to replace it. CROPICO will continue to develop new instruments and to update the design of existing models, and therefore will be able to offer an instrument suitable for your needs.
