Operating time

Operating time without changing batteries**

GSM-transfer	Measurement cycle
	1 minute	5 minutes	15 minutes	60 minutes
none	1 year	4 years	9 years	10 years
1 x daily	1 year	4 years	7 years	10 years
1 x weekly	1 year	4 years	8 years	10 years
1 x monthly	1 year	4 years	9 years	10 years

** The lifetime arises as a result of the optionally available equiment with lithium batteries.
With according to the standard used alcaline batteries the indicated lifetime halves itself.

Operating time without charging batteries

GSM-transfer	Measurement cycle
	1 minute	5 minutes	15 minutes
none	50 days	3 months*	3 months*
1 x daily	45 days	3 months*	3 months*
1 x weekly	50 days	3 months*	3 months*
1 x monthly	50 days	3 months*	3 months*

* Limited by the self discharge of the internal NC batteries (with external rechargeable battery up to 1,5 years)
