2. PRESENTATION OF THE INSTRUMENTS 2.1. PRESENTATION OF THE C.A 1821 AND 1822 T1 input. T2 input. C.A 1821 C.A 1822 THERMOCOUPLE THERMOMETER THERMOCOUPLE THERMOMETER Backlit LCD display unit. Keypad with 5 keys. °C / °F °C / °F MEM REC HOLD MEM TYPE MAX MIN REC On/Off key. Type B micro-USB connector.
2.2. PRESENTATION OF THE C.A 1823 Probe input. C.A 1823 RTD PROBE THERMOMETER Backlit LCD display unit. Keypad with 5 keys. °C / °F MEM REC HOLD TYPE MAX MIN On/Off key. Type B micro-USB connector. 2.3. FUNCTIONS OF THE INSTRUMENTS The C.A 1821 and the C.A 1822 are thermocouple-based thermometers with one and two channels, respectively.
2.4. ON/OFF KEY A long press on the key switches the instrument on. A second long press on the key switches the instrument off when it is on. However, it is not possible to switch the instrument off when it is in record mode and is recording. REC If during start-up the instrument displays the screen shown opposite, it means that a recording session has been brutally interrupted by a power outage. During the display of this screen, the instrument recovers the recorded data.
2.6. DISPLAY P MIN MAX REC MEM FULL HOLD MEM T2-T1-T2 MAX MIN T1 Secondary display unit (for the C.A 1822). Main display unit. PT1000 K J T E N R S When the sensors or the probes are not connected, the instrument indicates - - - -. When the measurement exceeds the limits (whether positive or negative), the instrument displays OL. P : indicates that auto-off is disabled and the instrument is in permanent mode.
3. USE IN STAND-ALONE MODE The instruments can operate in two modes: the stand-alone mode described in this section, the record mode, in which they are controlled by a PC. This mode is described in the next section. 3.1. TEMPERATURE MEASUREMENT Connect the sensor(s) to the instrument. On the C.A 1821, connect one thermocouple. On the C.A 1822, connect one or two thermocouples of the same type. On the C.A 1823, connect one PT100 or PT1000 probe.
To display the measurements in °F, press the °C/°F key. Wait for the display to stabilize before reading the measurement. For more information about the response times of the sensors, refer to §5.2.3. 3.2. OTHER FUNCTIONS If 2 sensors are connected to the C.A 1822, it is possible to display the difference between the measurements of the two sensors by pressing the key. The instrument then displays T1-T2 on the upper display unit. A second press restores the display of T2.
Er.12: The update of the internal software is not compatible with the electronic boards in the instrument. Reload the previous internal software into your instrument. Er.13: Recording scheduling error. Check that the instrument’s time and the time of the Data Logger Transfer software are the same.
4. USE IN RECORDING MODE The instruments can operate in two modes: the stand-alone mode described in the previous section, the record mode, in which they are controlled by a PC. This mode is described below. 4.1. CONNECTION The device has 2 communication modes: A USB link via a USB-micro USB cord, A Bluetooth 4.0 BLE wireless link. 4.2. GET DATA LOGGER TRANSFER SOFTWARE Visit our web site to download the latest version of the application software: www.chauvin-arnoux.
4.4. BLUETOOTH LINK The instrument has a low-energy Bluetooth 4.0 link that requires no pairing. Activate Bluetooth on your PC. If your PC does not have a Bluetooth link, you can add a board or Bluetooth adapter connected to a USB port (see §1.2). Since Windows 7 does not manage low-energy Bluetooth, a specific USB/Bluetooth adapter must be used (see §1.2). Switch the instrument on by a long press on the symbol is displayed. key, then activate the Bluetooth link by a long press on the key.
4.5.2. DATE AND HOUR The Instrument menu lets you set your instrument’s date and time. These cannot be changed while recording or when a recording session has been scheduled. By clicking , you can choose the date and time display formats. 4.5.3. AUTO OFF As default, the instrument switches itself off automatically after 3 minutes of operation without the user’s presence being confirmed by a key-press. By clicking , you can change this value to 3, 10, or 15 minutes.
4.5.5. DISPLAY By clicking , then opening the Thermometer tab, you can modify the units in which the measurements are displayed in the same way as by pressing the or °C/°F or TYPE keys. 4.5.6. ALARM By clicking , then opening the Alarms tab, you can program an alarm threshold in each of the measurement channels. The alarm may be triggered if the measurement is: above a high threshold, below a low threshold, between 2 thresholds, above the high threshold or below the low threshold 4.5.7.
4.5.11. FORMATTING THE MEMORY OF THE INSTRUMENT The internal memory of the instrument is already formatted. But if there is a problem (if it becomes impossible to read or to write), it may be necessary to reformat it (in Windows). In this case, all of the data will be lost.
5. TECHNICAL CHARACTERISTICS 5.1. REFERENCE CONDITIONS Quantity of influence Reference values Temperature 23 ± 2°C Relative humidity 45% to 75% Supply voltage 3 to 4.5V Electric field < 1V/m Magnetic field < 40A/m The intrinsic uncertainty is the error specified for the reference conditions. θ = temperature R = reading 5.2. ELECTRICAL CHARACTERISTICS FOR THE C.A 1821 AND C.A 1822 5.2.1.
This temperature rise does not occur when the instrument is connected to a wall outlet or when it is powered by batteries. Do not connect the C.A 1821 or the C.A 1822 to a PC to make measurements. Use this connection only to program the instrument or to transfer records. 5.2.3. RESPONSE TIME The response time is the time at the end of which the e.m.f. reaches 63% of its total variation when the thermocouple is subjected to a temperature step.
5.3.2. VARIATION WITHIN THE RANGE OF USE Quantities of influence Temperature Range of influence Quantity influenced Influence -10 to + 60 °C θ ± 0.13°C / 10°C 5.4. MEMORY The size of the flash memory containing the records is: -2MB for the C.A 1821 and the C.A 1823, -4Mo for the C.A 1822. These capacities are sufficient to record one million measurements. Each measurement is recorded with the date, the time, and the unit. For the instrument with 2 channels, both measurements are recorded. 5.5.
5.8. ENVIRONMENTAL CONDITIONS For use indoors and outdoors. Operating range -10 to 60°C and 10 to 90%RH without condensation Storage range -20 to +70°C and 10 to 95%RH without condensation, without batteries Altitude < 2000m, and 10,000m in storage.
