Operation
POWER ON
Plug in the adaptor and the meter turns on automatically with a short beep. If the vo ltage is too high or low, “bAt“ will displa y on the LCD and an LED will flash. The LCD will display current CO displayed as well
TAKING MEASUREMENT
The meter starts measurements when powered on and updates readings every second. If the operating environment changes (ex. from high to low temp.), it takes 2 minutes for the CO to respond and 10 minutes for RH change.
NOTE: Do not hold the meter close to your mouth or any other source of CO
MAX/MIN
In the normal mode, press the MIN/MAX button to see the minimum and maximum of CO2, Temperature and Humidity. Each press of MIN/MAX button will sequence through the MIN, MAX display and then returns to normal mode.
Press and hold the RESET button for more than 1 second to clear the minimum and maximum value from memory.
DATA LOGGING
The meter can record readings of CO monitoring. The memory capacity is 15999 points (5,333 RH, Temperature and CO The sam pl e ra te is adj us ta ble fro m 1 s e c o n d t o 4 hours 59 minutes and 59 seconds.
After the sampling rate is selected, press the LOG button for 2 seconds in the normal mode to start logging. The green LED light blinks to indicate the logging status and t he L CD main display will alternate between real time CO the real time temperature, humidity and clock.
