Battery Replacement

The Meter uses a 9V battery (NEDA 1604 or IEC 6F22). To replace the battery,

remove the two screws of the battery compartment from the back of the Meter

and lift off the cover of the compartment. Replace the battery. Reattach the

battery compartment to the back of the Meter, and reinstall the screws.

Ranges & Accuracy

Accuracy is give as ± ([% of reading] + [number of least significant digits]) at
18°C to 28°C with relative humidity up to 80%, for a period of one year after
calibration.
