Clock Display Mode
The real‐time clock has a 24‐hour format. View it using the DN/MODE button when cover is open or by
externally using the magnetic switch. As the MODE changes, “cloc” displays briefly. The RT‐10 uses the
real‐time clock for the Sleep Timer (to conserve energy) and the Battery Timer (for indicating battery
life). Use the SEL button or magnetic switch to view the number of days of battery use and the
remaining days on the timer. The Clock display reverts to “sleep” mode after a programmed period of
inactivity where the device receives no pulses and activates no switches.
Programming the RT‐10
You can program the RT‐10 in the hazardous area with the cover on using the magnetic switches, or
outside the hazardous area with the cover removed using the programming buttons.
If you remove the cover for programming, you must do this outside the hazardous area.
To scale the rate and total displays and the optional analog output, the RT‐10 requires programming of
the K‐factor, Rate time‐base, Gate Time, and Analog Output or Fiber‐optic Output Scaling (if applicable).
Use the RT‐10’s three main display modes to access programming. With their respective variables, these
are:
RATE Display TOTAL Display CLOCK Display
Time‐base for Rate K‐factor (pulses/engineering unit) set time
Gate Time sleep timer
Analog Scaling (loop power option only)
Frequency Scaling (fiber optic option only
