  • Page 8: Keyboard And Menu Description

    The pressing of a key is accompanied by a short confirmation beep: a longer beep sounds if the wrong key is pressed. The HD2127.1 and HD2127.2 models measure two temperatures: the temperature corresponding to input A is displayed in the main line. The temperature detected by input B is displayed in the secondary line.
  • Page 9 Automatic turning off The instrument has an AutoPowerOff function that automatically turns the instrument off after about 8 minutes if no key is pressed during the intervening time. The AutoPowerOff function can be disabled by holding the HOLD key pressed down during the turning on phase: the battery symbol will blink to remind the user that the instrument can only be turned off by pressing the <ON/OFF>...

  • Page 14: The Probes

    THE PROBES The instrument works with temperature probes fitted with the SICRAM module (with a Platinum Pt100 sensor with 100Ω resistance), with direct 4-wire Pt100 sensor, 2-wire Pt1000 or 2-wire Ni1000. The excitation current was chosen in order to minimize the sensor self-heating effects. The SICRAM module acts as an interface between the sensor on the probe and the instrument.

  • Page 15: Instructions To Connect The Tp47 Connector For 4-Wire Pt100, 2-Wire Pt1000 And Ni1000 Probes

    Instructions to connect the TP47 connector for 4-wire Pt100, 2-wire Pt1000 and Ni1000 probes All Delta Ohm probes are provided with a connector. The HD2127.1 and HD2127.2 instruments also work with direct 4 wire Pt100, 2 wire Pt1000 and Ni1000 probes manufactured by other producers: for the instrument connection is prescribed the TP47 connector to which the probe's wires should be welded.
  • Page 16 Open the two module shells: the printed circuit to which the probe must be connected is housed inside. On the left there are the 1…4 points on which the sensor wires must be welded. The JP1…JP4 jumpers are in the center of the board. These must be closed with a tin bead for some type of sensors: Not Used Ni1000...

    Direct connection of 4-wire Pt100 sensors 4 wire Pt100 sensors can be soldered Sensor Direct soldering to the connector directly to the pins of the free female connector without making use of the TP47 board. The 4 wires of the Pt100 sensors have to be soldered as indicated in the figure on the left.

  • Page 18: Warnings And Operating Instructions

    WARNINGS AND OPERATING INSTRUCTIONS 1. Do not expose the probes to gases or liquids that could corrode the material of the sensor or the probe itself. Clean the probe carefully after each measurement. 2. Do not bend the probe connectors or force them upward or downward. 3.

  • 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 discharged, 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.
