Page 6: Description Of The Functions
DESCRIPTION OF THE FUNCTIONS The keyboard of the Anemometer Model HD2303.0 is composed of double-function keys. The function on the key is the "main function", while the one above the key is the "secondary function". When the instrument is in standard measurement mode, the main function is active. Once the Settings Menu has been opened, by pressing simultaneously the DATA+UNIT keys, the secondary function is enabled. - Page 7 CLR/ESC key The "CLR" key has two functions: • CLEAR (CLR): allows to reset the maximum (MAX), minimum (MIN) and average (AVG) value of the captured measurements; • ESC: once the MENU has been opened with the DATA+UNIT keys, the CLR key will allow to cancel the parameters set using the ...
- Page 8 UNIT/MENU key The UNIT key is used for the following functions: • UNIT: by pressing this key the unit of measurement of the main input quantity is selected: the unit of measurement will appear in the upper part of the display; the measured value will be displayed in the central line.

THE PROGRAMMING MENU To access to the menu press simultaneously the following keys: The items to be set are listed in this order: 1. SECT m - SECT inch : this parameter defines a duct's section area for flow rate calculation. -
Page 10: Probes And Measurements
PROBES AND MEASUREMENTS The Anemometer works with hot-wire, vane and temperature probes fitted with the SICRAM module. It works also with temperature probes with 4 wire Pt100 or 2 wire Pt1000 sensor. Some probes are fitted with SICRAM module that acts as an interface between the sensor on the probe and the instrument. -
Page 11: Flow Rate Measurement
Flow rate measurement The flow rate measurement requires knowledge of the duct or vent area orthogonal to the flow: the menu items indicated by "SECT m2" and "SECT INC2" define the section area m or inch To set the area value: press simultaneously DATA and UNIT to open the menu;... -
Page 12: Hot - Wire Wind Speed Measurement Probes Complete With Sicram Module
SICRAM WIRE WIND SPEED MEASUREMENT PROBES COMPLETE WITH MODULE The hot-wire wind speed measurement probes, fitted with SICRAM module, are the models: AP471S1, AP471S2, AP471S3, AP471 S4 The AP471S1 and AP471S3 probes measure incident air flows up to 40m/s. The AP471S2, AP471S4 probes are fitted with an omnidirectional sensor allowing measurement of speeds up to 5m/s in any direction of the air flow incident on the probe. -
Page 13: Operation
Operation Where present, extend the telescopic rod to the necessary length paying attention to the cable so that it can slide freely and without strain. Uncover the sensor and introduce the probe in the air flow being measured, maintaining the arrow at the top of the probe parallel to the flow, as indicated in the figures. -

Page 16: Vane Wind Speed Measurement Probes Complete With Sicram Module
SICRAM ANE WIND SPEED MEASUREMENT PROBES COMPLETE WITH MODULE The AP472S1 and AP472S2 vane probes measure the incident wind speed and flow rate. The probe AP472S1 measures also the temperature using a thermocouple of type K. On request, they can be fitted with a telescopic rod that eases measurements in areas difficult to reach (for example vents). -
Page 17: Care And Maintenance Of The Probes
The probe should be maintained orthogonal to the flow and not tilted in relation to it The probe is correctly positioned in relation to the air-flow when the value measured is the maximum possible. Proceed with measurement following the instructions provided in this chapter. Care and maintenance of the probes The probe performance, mainly at low speeds, largely depends on the very slow friction of the vane on its own axis. -

Pt100 Pt1000 T IRECT INPUT EMPERATURE PROBES The instrument accepts the input of Platinum temperature probes with resistances of 100Ω (Pt100) and 1000Ω (Pt1000). The Pt100 are connected to 4 wires, the Pt1000 to 2 wires; the excitation current was chosen in order to minimize the sensor self-heating effects. -

Page 23: 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. -
