OPERATION AND MEASUREMENT

MQ series quantum meters are designed with a user-friendly interface allowing quick and easy measurements.

To power the meter, slide the included battery (CR2320) into the battery holder, after removing the

battery door from the meter's back panel. The positive side (designated by a "+" sign) should be facing out from

the meter circuit board.

Press the power button to activate the LCD display. After two minutes of non-activity the meter will revert

to sleep mode and the display will shut off to conserve battery life.

Press the mode button to access the main menu, where manual or automatic logging are selected, and

where the meter can be reset.

Press the sample button to log a reading while taking manual measurements.

Press the up button to make selections in the main menu. This button is also used to view and scroll

through the logged measurements on the LCD display.

Press the down button to make selections in the main menu. This button is also used to view and scroll

through the logged measurements on the LCD display.

Logging: To choose between manual or automatic logging, push the mode button twice and use the up/down

button two more times to exit the menu. When in SMPL mode press the sample button to record up to 99 manual

30 minutes the meter will average the sixty 30 second measurements and record the averaged value to memory.

The meter can store up to 99 averages and will start to overwrite the oldest measurement once there are 99

measurements. Every 48 averaged measurements (making a 24 hour period), the meter will also store an

integrated daily total in moles per meter squared per day (mol m

The LCD display consists of the total number of logged
