Frequently Asked Questions (FAQ's)

I cannot turn off my meter, do you know why?

Often times, the meter cannot be turned off because it is in recording mode ("REC" mode). Make sure to exit that function by holding down the

REC button before attempting to turn the meter off.

How long can I record for?

Battery life will depend on a number of factors:

• Quality of Battery

• Whether the beeper is ON or OFF

• Whether the backlight is ON or OFF

• Environmental Conditions during data logging

As a reference, using alkaline batteries with both the backlight and beeper on while automatic data logging at a 2 second sampling rate; the batteries will last approximately 14 hours.

Product Care

To keep your instrument in good working order we recommend the following:

• Store your product in a clean, dry place.

• Change the battery as needed.

• If your instrument isn't being used for a period of one month or longer

please remove the battery.

• Clean your product and accessories with biodegradable cleaner. Do not

spray the cleaner directly on the instrument. Use on external parts only.
