Low12VCount
Station Status: Number of times voltage has
dropped below 12V
Keyboard: Status Table ≈ line 21
CRBasic: variable = status.keyword
Increments by 1 each time the primary CR1000
supply voltage drops below ≈9.0. Updated with each
Status table update. The following applies to the
CR800 and CR1000 dataloggers. A variation may
apply to the C6 and CR3000: The 12 Vdc-low
comparator triggers at about 9.0 Vdc. The
minimum-specified input voltage of 9.6 Vdc will not
cause a 12 Vdc low condition, but a 12 Vdc low
condition will stop program execution before
measurements are compromised.
