Figure 4-43. Temperature Deadband Of 1°F
pH High Alarm
You can set the alarm value to the highest measurable value for the pH device.
For example, the highest value you can set for pH high alarm is 14 pH.
pH Low Alarm
You can set alarm value to the lowest measurable value for the pH device. For
example, the lowest value you can set for pH low alarm is 0 pH.
pH Deadband
pH dead band value is always a positive number. Below are examples of
deadband settings for pH transmitters.
1. High alarm state - If you set pH deadband to 2 and the high alarm value
to be 10 pH, the device will be on high alarm state (red LED blinks 2 times
every 2 seconds) when pH measurement reaches 10pH or above. The device
will stay in the alarm state until the pH measurement reaches 8pH or below
(“high alarm value – deadband value”).
2. Low alarm state - If you set pH deadband to 2 and the low alarm value to be
7 pH, the device will be on low alarm state (red LED blinks 2 times every 2
seconds) when pH measurement reaches 7pH or below. The device will stay
in the alarm state until the pH measurement reaches 9pH or above (“low
alarm value + deadband value”).
