The following settings can be configured via CalexConfig.
Configuration settings are password protected. To access the Settings menu, go to the Unlock
screen and enter the password. The default password is 1234.
Temperature Units
On the temperature display screen, click °C or °F to switch between temperature units.
Output Processing
Go to the Settings screen, then Output Processing.
4 to 20 mA Output Scale
•
Set the temperature range limits for the 4 to 20 mA output, between the limits of
-20°C and 1000°C.
The difference between the temperatures at 4 mA and at 20 mA must be at least
100°C. The temperature at 20 mA must be greater than the temperature at 4 mA.
Default setting: Depends on model, e.g. LT = -20°C to 100°C (see Model Numbers)
•
Averaging Period
Set the time, in seconds, over which the measured temperature is averaged.
Note: averaging prevents the sensor from following rapid temperature changes.
Default setting: 0
•
Peak/Valley Hold Processing
If required, hold processing can be applied by setting Hold Mode to "Peak" or "Valley"
and setting the hold period. This is useful if the temperature reading is interrupted by
gaps between moving objects, or by an obstruction.
Default setting : OFF
Emissivity and Compensation
From the Settings menu, go to Emissivity and Compensation.
•
Emissivity Setting
Enter the emissivity of the target. Target emissivity can be determined experimentally,
or estimated using an emissivity table. For more information, contact Calex.
Default setting: 0.95
•
Reflected Energy Compensation On/Off
If enabled, compensates for errors caused by reflected energy from hotter or colder
objects. This should generally be kept OFF in most applications.
Default setting: OFF
Reflected Temperature
•
Enter the temperature of the surroundings of the target for Reflected Energy
Compensation. Changing this has no effect if Reflected Energy Compensation is OFF.
OPERATION
Once the sensor is in position, a suitable safety barrier or isolator is connected and
configured, and the appropriate power and cable connections are secure, the system is ready
for continuous operation by completing the following simple steps:
1
Turn on the power supply
2
Turn on the meter, chart recorder or controller
3
Read or monitor the temperature
