Page 8: Inputs Configuration And Display
INPUTS CONFIGURATION AND DISPLAY The HD2124.1 and HD2124.2 are instruments with two pressure and temperature inputs. To measure pressure, the PP471 SICRAM module is used with one of the Delta Ohm TP704 or TP705 probes. The temperature is measured using Pt100 probes fitted with SICRAM module or 4-wire Pt100 probes. -
Page 9: Keyboard And Menu Description
KEYBOARD AND MENU DESCRIPTION Foreword The instrument keyboard is composed of single-function keys, like the UNIT 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 10 disabled by holding the HOLD key pressed down when turning the instrument on: the battery symbol will blink to remind the user that the instrument can only be turned off by pressing the <ON/OFF> key. The automatic turning off function is disabled when external power is used. On the other hand, it cannot be disabled when the batteries are discharged.

- Page 12 • In the absolute pressure probes, apply the vacuum by using a suitable pressure calibrator. The "PRES_REL_TO_ZERO ENTR_TO_MENU" message appears: press REL to zero the pressure or press ENTER to access other menu items. Press A/B – ESC to toggle from one channel to the other: the zero is still applied to both A and B channels.
- Page 13 PEAK key - only HD2124.1 PEAK/MENU key - only HD2124.2 The PEAK (HD2124.1) or PEAK/MENU (HD2124.2) keys enable the pressure peak measurement circuit. When two probes are present, use the A/B key to move from one channel to the other.

Page 15: The Probes
THE PROBES The instrument measures absolute, relative and differential pressure using the PP471 SICRAM module and the TP704 and TP705 series probes. It also measures the temperature with a Pt100 sensor fitted with SICRAM module or 4-wire Pt100 probes. The SICRAM module acts as an interface between the sensor on the probe and the instrument. There is a microprocessor circuit with a permanent memory inside the module that enables the datalogger to recognize the type of probe connected and to read its calibration information. -

(do not use water or solvents). This method also improves the response time. Instructions to connect the TP47 connector for 4-wire Pt100 All probes produced by Delta Ohm are provided with a connector. The HD2124.1 and HD2124.2 instruments also work with 4-wire direct Pt100 probes manufactured by other producers: for the instrument connection is prescribed the TP47 connector to which the probe's wires should be welded. -
Page 17: Direct Connection Of 4-Wire Pt100 Sensors
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. For the 4-wire Pt100 sensor the jumpers must be left open. -
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. Some pressure probe models are suitable for measurement of non corrosive gases or air and dry and not liquid only: check the membrane compatibility with the plant fluid. -

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. -
