Sleep Mode
In order to conserve the battery, the RT‐10 reverts to “sleep” mode after a specific period of inactivity
where the device receives no pulses and activates no switches. See page 20 for information on
programming the “sleep time” period.
Low Battery
The RT‐10 has an ON‐time battery timer with a factory‐specified limit of 700 to 1400 days, depending on
options. After the time limit expires, “Lo Bat” appears briefly on the display whenever you change
modes. This means you should change the battery. The device continues to display “Lo Bat” until you
change the battery and reset the timer. See page 21 for instructions.
Rate Display Mode
View the Rate using the DN/MODE button when the cover is open, or by using the magnet switch when
the cover is closed. As the MODE is changed, “rate” displays briefly. The rate displays initially with five
decimal places. The decimal point “floats” to the right as the rate increases. The rate displays based on
the number of pulses the RT‐10 counts during a “gate time” period.
“Gate time” is programmable. Increasing the gate time interval produces a filtering or averaging effect
useful for stable display of uneven or intermittent flows. The Rate display reverts to “sleep” mode after
a programmed period of inactivity where the device receives no pulses and activates no switches.
