Press RECALLMODE to switch to temperatures display(Fig.4,5,6). The lower display shows the real time clock.

CO2 (Carbon Dioxide)

MODE

Press RECALL to switch the mode to CO2.User can get the CO2 reading in ppm unit on main display.(Fig.7). The lower display shows the real time clock.

DATA HOLD

In normal display mode, press HOLD to freeze the readings, "HOLD” icon is flashed on the left top of LCD (Fig.8). All current readings are kept unchanged. Press HOLD again to cancel the hold function.

NOTE:

The hold function is disabled in Min/Max/Avg mode.

BACKLIGHT

The backlight will be activated for 10 seconds by pressing any key.

MIN,MAX,AVG,CURRENT REVIEW

This meter allows you to check the minimun, maximum, average, current value from the moment you press the

	MIN		key. Under normal mode, each press of	MIN		displays

In this max/min/avg/current modes, it shows the

corresponding readings on main display and the accumulated time of how long you are in this mode. The maximum time interval for this function is 18 hours.

MODE

Press RECALL can switch the displayed parameters. (Fig.13)

Distinguishing the normal display and current review by checking the time display format. In normal display, date & time are displayed in turns. In current review, the lower display is the accumulated time of how long you are in max/min/avg mode.

ALARM

The meter features audible alarm to give warnings when CO2 concentration exceeds the limit. (See “Meter Setup” section for setting alarm threshold). It emits beeps (Abt. 80dB) when CO2 level goes over the set value and stops only when the readings fall below the set value. It beeps again when value goes over the limit.

AUTO POWER OFF

The meter turns off automatically after 20 minutes of inactivity. To override the function, first, the meter is in power off status. Hold down ON/OFFSET and HOLD for 2 seconds to turn on the meter until “n” appears.(Fig.14)

NOTE:

Auto sleep function will be disabled during calibration & auto recording mode. Auto sleep function WILL NOT be

disabled automatically via using adaptor. Fig.14

MANUALLY RECORDING

MEM

The meter features a 99 point memory. In the normal or hold mode, press key to start recording, the REC icon and the main display will be flashed 3 times. The

memory sequential number will show on the main display with 99 points in maximum. The data in the memory contains all parameters information and not only the displayed parameter. When all 99 points memory are occupied, a “FULL” message will be displayed on the screen. If you think the reading is changing too fast, you can press

HOLD key to freeze current reading first then manually record the data. This recording function will be disabled in the Min/Max mode.

99 MEMORIES RECALL

MODE

In normal or hold mode, press RECALL key for more than 2 seconds until the Recall icon flashes. Press HOLD or MEM to scroll the memories. The memory sequential number displays on main LCD first and reading comes after. (Fig16&17). Press key to switch the display parameter.(Fig.18).The time displayed in memory recall mode is the recording time of this memory.

DATA LOGGING

The meter can automatically record Humidity/TEMP./CO2 for long term environment monitor. The memory capacity is 6000 points for each parameter. Users can set up sampling rate from 1 second to 4hours 59 minutes and 59 seconds. The factory preset rate is 30 second.

ON/OFF

To setup the sampling rate, when meter is powered on , hold down SET for more than

P60 (rAtE) and press MAX/AVG

Press HOLD or MEM to select the sample rate from hour, minute to second and then press

MIN	to confirm. Press START	to return to normal.
MAX/AVG
	ESC

After sampling rate is selected, press STARTESC for 2 seconds under normal mode to start logging. The REC icon flashes to indicate the logging status and LCD main display

shows the real time value. Lower displays are real time clock.(Fig.19)

Battery low indicator

A battery low icon “ “ appears when the supplied power is too low to maintain a normal operation. Please replace the batteries for accurate measuring. Suggest to use adaptor (optional part: AC1214) for long term measuring & datalogging.

Humidity Calibration

This meter can be calibrated either via 35% & 80% salt bottle or humidity generator. The ambient condition is recommended as stable 25oC. While the meter is powered off, plug the sensor probe into 35% salt. Press MEM simultaneously for 3 seconds to turn on the meter and enter calibration mode. Press HOLD or MEM to select

MIN

35.0% calibration and press MAX/AVG to start. “CAL” and calibrating value are blinking on the LCD.

CAUTION:

Do not calibrate the humidity without the default calibration salt. Otherwise, it will cause permanent damage. Contact ROTRONIC for calibration salt or services.

Single point calibration will cause error code E11 or non accurate reading. Always do dual point calibration to complete a process. Suggest to calibrate low humidity first.

CO2 Calibration

The sensor has an automatic calibration function to secure long-term accuracy. If a

calibration is desired, press	ON/OFF	START	MEM	simultaneously for 3 seconds to turn on the
	SET	ESC
meter and enter calibration mode. Press HOLD or								MEM	key to select 400 ppm CO2
					MIN		to start and see“CAL” and CO2 value

blinking on LCD. Wait about 10 minutes until the blinking stops and the calibration is completed and back to normal mode. While choose 0 ppm CO2 calibration, remove the cap from meter rear side and plug the CO2 CALIBRATOR pipe into the sensor hole beneath. Wait about 10 min until the blinking stops and the calibration is completed and back to normal mode.

CAUTION:

Do not calibrate the meter in the air with unknown CO2 concentration. Otherwise, it will be calibrated as 0 or 400ppm by default and leads to inaccurate measurements.

Ensure the batteries are with full voltage during the calibration to prevent from interruption or failed calibration. When the accuracy becomes a concern after a long time usage, return to dealers for standard calibration.

Repeat above to start another run of logging. While the logging
