The Z1 comes from the factory with a default
dive profile sampling rate with a 20-sec-
ond interval. However, you can select from
10/20/30/60 seconds.
If you shorten the sampling rate interval,
the amount of data logged for each dive will
increase, which means the profi le time will be
shortened.
The Z1 can hold about 80 hours of profi le data
at the default sampling rate of 20 seconds. If you set the sampling rate to
10 seconds, the Z1 will be able to hold about 40 hours of data.
How to Set
• When dive log data is displayed, press-and-hold the ADJUST button for
about 2 seconds to switch to the sampling rate setting screen.
• Press the LED/LOG button or the PLAN button to change the setting.
• Press the ADJUST button to save the new setting.
