Clock, Time, Battery, and Temperature
This display shows the real time clock, the date, the battery voltage in
raw count and temperature sensor reading.
Sensor Expiration Date
The expiration date (month and year) for each installed sensor is
based on the manufacturing date and expected life of each sensor.
If the current date exceeds the expiration date for any sensor, the
performance of the given sensor cannot be guaranteed. It is strongly
recommended to replace the sensor immediately to ensure proper
operation.
Pump Stall
The “Pump = 20/20” reading is the minimum and maximum pump raw
count (RC), and “Stall = 40 +/-” is the pump stall threshold. The pump
stalls if the maximum raw count reaches the pump stall threshold, which
causes the pump to shut off. To determine the pump stall threshold:
[ (max RC when pump is free + max RC when pump is blocked) ] ÷ 2
To adjust the pump stall threshold, press [Y/+] to increase or [N/-] to
decrease the numerical value.
Back Light Threshold
Adjust the threshold for the LCD backlight to automatically turn on/off;
verify the threshold is 100, which is suitable for most situations.
Serial Number and Pump
Displays the monitor’s serial number and the pump status. If a pump
is installed and a pump speed control circuit is available, toggle the
display “Pump=Low/High” by pressing [N/-] .
NOTE
: Changes made are
only for testing the pump condition and are not saved to the nonvolatile
memory.
Refer to Change Pump Speed on page 25.
Battery Duration Time
Use to test battery life and displays the last run time before the unit
turned itself off due to low battery.
