Press MEM to select °C or °F and then press to normal. to confirm. Press to return
TAKING MEASUREMENT
The meter starts measurement when power on and update readings every second.
In the condition of operating environment change, it takes 30 seconds to
respond for CO₂ sensor.
NOTE: Do not hold the meter close to faces in case exhalation affects CO2 to normal.
Humidity
Press MODE RECALY to switch to humidity display. (Fig.3).The lower display shows the real time clock.
TEMP, DP,WBT
Press MODEN RECALY to switch to temperatures display(Fig. 4,5,6) The lower
display shows the real time clock.
S CO2 Carbon Dioxide)
Press 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 to freeze the readings, “HOLD” icon is flashed
on the left top of LCD (Fig.8). All current readings are kept unchanged. Press
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.
N.MAX.AVG. CURRENT REVIEW
This meter allows you to check the minimum, maximum, average, current value
from the moment you press the key. Under normal mode, each press of displays
MIN, MAX, AVG and current value in sequence. (Fig.9~11). To return to normal
mode, press to escape(Fig. 12) 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.
Press 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.
NOTE: “
HOLD” & “MANUALLY RECORD” & “RECALL” functions are disabled in Min/ Max Ava
mode.
ALARM
The meter features audible alarm to give warnings when COz 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 ONIOFE SET
and *ow 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.
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 parameter 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 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
In normal or hold mode, press RECALY key for more than 2 seconds until the
Recall icon flashes. Press or to scroll the memories. The memory sequential
number displayed 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 memo.
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. To setup the sampling rate, when meter
is powered 2 seconds until entering meter setup mode. Press P60 (rAtE) and
press ( key to enter. hold down for more than key to select the program Press
to select the sample rate from hour, minute to second and then press confirm.
Press to return to normal. After sampling rate is selected, press SAy for 2
seconds under normal mode to start logging. The REG icon flashes to
indicate the logging status and LCD main display shows the real time value.
Lower displays are real time clock. (Fig. 19)
Repeat above to start another run of logging. While the logging space is full,
it shows “FULL”. To terminate data logging, press for 2 seconds, REC icon
stops flashing.
Press is key to switch to the mode you want to see. Except the mode switching
function, auto power off, min/max, manual record, hold and recall functions
are all disabled during logging.
Meter Setup
When meter is powered on, hold down meter setup mode. To exit setup, press SET
for more than 2 seconds until entering STARI ESC to return to normal mode.
Press key to select the program and press The programmable setting flashes on
display, press press key to confirm. To leave without saving, press key to
select. or MEN key to select and key to return.
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 25°C. While the
meter is powered off, plug the sensor probe into 35% salt. Press
simultaneously for 3 seconds to turn on the meter and enter calibration mode.
Press HOLD or H to select 35.0% calibration and press 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 IN simultaneously for 3 seconds to turn on
the meter and enter calibration mode. Press now or MEN) key to select 400 ppm
CO₂ calibration (Outside Air calibration). Press 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.
