  • Page 8: Keyboard And Menu Description

    KEYBOARD AND MENU DESCRIPTION Foreword The instrument keyboard is composed of single-function keys, like the MENU key, and double- function keys such as the ON-OFF/Auto-OFF key. In the double-keys, the function in the upper part is the “main function”, while the one in the bottom part is the “secondary function”.
  • Page 9 This setting changes the information displayed and the immediate print of data (SERIAL key). The data recorded using the LOG function (HD2178.2) and sent to the printer or PC through the serial port using the SERIAL function (HD2178.1 and HD2178.2), keep the chosen unit of measurement and display it.
  • Page 10 ENTER key In the menu, the ENTER key confirms the displayed parameter and then goes to the next one. REL/ In measurement mode, it displays the difference between the current value and that measured on pressing the key. The REL message appears on the display; press the key again to return to the cur- rent measurement.
  • Page 11 When turned on, the temperature probes direct 4-wire Pt100, the Pt1000 and the Ni1000 display the message "CH_B_NO_SER_NUM" (no probe serial number); in this case the probe type must be entered manually. Select Probe type using the MENU key, CH_B and then the type of probe used with the arrow keys;...

  • Page 14: The Probes

    THE PROBES Input A accepts K, J, T, N or E thermocouple temperature probes. The thermocouple type is set up by menu. The connector contacts of thermocouple probe are polarized, they have to be put into the miniature connector placed in the instrument on the right way. Usually the probes are marked with the symbol + and -: these symbols have to correspond to the relevant symbols placed on the rubber protection of the instrument.

    Instructions to connect the TP47 connector for 4-wire Pt100, Pt1000 and Ni1000 probes All Delta Ohm probes are provided with a connector. The HD2178.1 and HD2178.2 instruments also work with 4-wire direct Pt100, 2-wire Pt1000 and Ni1000 probes manufactured by other pro- ducers: for the instrument connection is prescribed the TP47 connector to which the probe's wires should be welded.
  • Page 16 The instructions to connect the Platinum or Nickel probe to the module are provided below. The module is supplied complete with fairlead and gasket for 5mm maximum diameter cables. Do the following to open the module and connect a probe: Unscrew the fairlead and extract the gasket, remove the label using a cutter, unscrew the ring on the opposite side as illustrated in the figure: Open the two module shells: the printed circuit to which the probe must be connected is housed in-...

  • Page 21: Low Battery Warning And Battery Replacement

    LOW BATTERY WARNING AND BATTERY REPLACEMENT The battery symbol on the display constantly shows the battery charge status. To the extent that batteries have dis- charged, the symbol "empties". When the charge decreases still further it starts blinking… In this case, batteries should be replaced as soon as possible. If you continue to use it, the instrument can no longer ensure correct measurement.
