The Model 42270 records Relative Humidity readings in addition to Temperature readings. Programming and data retrieval instructions are included on the Software CD located in the 42275 kit or at www.Extech.com. Description 1. Mounting hole 2. Status LEDs (Record and Alarm) 3. LCD display Displays LCD Display REC: HI and LOW: RH%: C or F: COMM: Displayed while logging readings. Displayed when the High or Low Alarm limit is exceeded. Relative Humidity Temperature units. Appears when Datalogger is communicating with a PC. Recording Status Indication Both the RED status LED and the display indicator `REC' will flash every 5 seconds if the sampling rate is set to 5 seconds or higher. If the sampling rate is set lower than 5 seconds, the indicators will flash every 1, 2, 3, or 4 seconds as programmed. ALARM Status Indication Both the YELLOW status LED and the display indicator `ALM' will flash when the recorded value is higher than the user programmed High Alarm value or lower than the Low Alarm value. The Alarm status LED and the `ALM' display indicator flash every 5 seconds if the sampling rate is programmed for 5 seconds or higher. If the sampling rate is set lower than 5 seconds, the indicators will flash every 1, 2, 3, or 4 seconds as programmed. Low Battery Indication When the lithium battery voltage nears the critical operating level, the LCD displays `LO'. To replace the battery, refer to the Battery Replacement section.

At least one 42275 kit is required per site. Note: The datalogger display will not switch on until activated by software. Note: The 42270 readout may turn gray if the ambient temperature falls below 32°F (0°C). It may also darken and become unreadable if the ambient temperature exceeds 122°F (50°C). This is expected operation. In both cases, the unit will log readings normally and will continue to log throughout the specified temperature measurement range. Battery Replacement When low battery icon (`LO') appears, replace the Lithium CR2 battery. 1. Open Datalogger by first removing the four (4) rear Phillips screws. 2. Carefully pry off the rear of the Datalogger. 3. The cylindrical lithium battery is located on bottom of PCB board. 4. Replace the battery, observing polarity. 5. Assemble the Datalogger housing.
