Example: Temperature sensor with a sensing range of 50-95°F - displayed in Fahrenheit
Gain = (95-50) / 4 = 11 (round to the nearest integer)
Offset = 50 - 11 = 39
Example: Temperature sensor with a sensing range of 50-95°F - displayed in Celsius
Convert 50-95°F to 10-35°C and use the Celsius range for the calculations
Gain = (35-10) / 4 = 6 (round to the nearest integer)
Offset = 10 - 6 = 4
Example: Humidity sensor with a range of 0 - 100% RH
Gain = (100-0) / 4 = 25
Offset = 0 - 25 = -25
High Limit 2: Applies only when the input type is Analog 4-20mA. The F3400/F1000 will
record an alarm and send notification when the F3400/F1000's calculated value exceeds this
limit. The High Limit 1 and High Limit 2 are disabled when they are both set to 0.
High Limit 1: Applies only when the input type is set for Analog 4-20mA. The F3400/F1000
will record an alarm and send notification when the F3400/F1000’s calculated value exceeds
this limit. The High Limit 1 and High Limit 2 are disabled when they are both set to 0.
Low Limit 1: Applies only when the input type is Analog 4-20mA. The F3400/F1000 will
record an alarm and send notification when the F3400/F1000's calculated value falls below this
limit. The Low Limit 1 and Low Limit 2 are disabled when they are both set to 0.
Low Limit 2: Applies only when the input type is Analog 4-20mA. The F3400/F1000 will
record an alarm and send notification when the F3400/F1000's calculated value falls below this
limit. The Low Limit 1 and Low Limit 2 are disabled when they are both set to 0.
Unit Of Measure (UOM): The 10 character field used to assign a unit of measure label to
analog values, such as °F, °C, % RH, Amps, Volts, PSI, etc. The unit of measure field is only
required when the input type is Analog 4-20mA. The unit of measure field is displayed on the
Main Menu and in notification (email/pager messages and SNMP Trap).
Alarm Label: Used for input identification. Applies to all input types except “Not Configured”.
For Analog input types, this label is displayed on the F3400/F1000 Main Menu and the Input
Configuration Menu. When the input alarms and/or returns to normal, the label is included in
the Alarm History and notification messages. For Digital NO and Digital NC inputs, the label is
displayed on the F3400/F1000 Main Menu, Input Configuration Menu, Alarm History page and
in notification messages only when the device is in alarm. For Digital Status inputs, the label is
displayed on the F3400/F1000 Main Menu when the input is on. When the input turns on, the
label is also included in the Digital Status History.
Normal Label: Applies to input types Digital NO, Digital NC and Digital Status. This field
may be left blank. If it is left blank, the F3400/F1000 displays the Label (from above). This
label is displayed on the main page when the input is normal, in the Alarm History when the
input returns to normal and in notification messages. For Digital Status inputs, the label is
displayed on the main page when the input is off. When the input turns off, the label is also
included in the Digital Status History.
