TOPSENSOR OFFSET
The subentry is only available for sensors in 2-color mode. It allows to correct the wide band temperature reading
by the addition of an offset value in a range from -200.0 to 200.0°C. The standard value is 0.0°C.
MATCH
adapts the temperature reading to the expected real object temperature. You can affect the current temperature
reading by overriding it with the real, alternatively measured, object temperature. In 1-color mode, the match
confirmation corrects the object emissivity value to match the current temperature reading. The match confirmation
in 2-color
mode adapts the slope value to match the current temperature reading. With the ▲ ▼ keys, you can
toggle between temperature match values from “LOW LIMIT” to “HIGH LIMIT” of the temperature range.
AVERAGE
defines the parameter for the signal post processing, see section 6.3.1 Averaging , page 55.
PEAK HOLD
defines the parameter for the signal post processing, see section 6.3.2 Peak Hold , page 55.
VALUE HOLD
defines the parameter for the signal post processing, see section 6.3.4 Valley Hold , page 58.
DECAY RATE
defines the linear signal decay for a given time span. The unit for the decay is in °C/s or °F/s, see Signal Drop:
Linear in section 6.3.2.3 Signal Drop with Reset , page 57.
ALARM SOURCE
sets the source for an alarm:
•
T
obj
– the object temperature is the alarm source
•
T
int
– the internal temperature of the sensor is the alarm source
SETPOINT
Once the setpoint is activated by providing a non-zero value, the relay changes state as the current temperature
passes the setpoint temperature. With the ▲ ▼ keys, you can toggle between setpoint values from “LOW LIMIT”
to “HIGH LIMIT” (e.g. 400.0 °C to 1800.0 °C).
For more information, see section 5.7.1.1 Setpoint , page 39.
DEADBAND
defines the deadband, see section 5.7.1.2 Deadband , page 39.
BACKGROUND CONTR
refers to the compensation source for the background temperature, see section 5.6.2.2 Background Temperature
Compensation , page 38.
•
NO COMPENSATION
– background temperature compensation is switched off
•
EXTERNAL mA IN
– temperature value for background compensation is taken from the external current
loop analog input
•
TEMP. VALUE
– temperature value for background compensation is taken from subentry BACKGROUND
TEMP.
BACKGROUND TEMP.
provides the temperature value for the background compensation.
With the ▲ ▼ keys, you can toggle between
values between
“LOW LIMIT” to “HIGH LIMIT” of the temperature measurement range.
