5.6.5 Limit 1 and Limit 2
Limit 1 and limit 2, index 0x80n0:13, [
}
157] index 0x80n0:14 [
}
157]
(not for EL3318)
A temperature range can be set that is limited by the values in the indices 0x80n0:13 [
}
157] and 0x80n0:14
[
}
157] . If the limit values are overshot, the bits in indices 0x80n0:07 [
}
157] and 0x80n0:08 [
}
157] are set.
The temperature value is entered with a resolution of 0.1 °C.
Example:
Limit 1= 30 °C
Value index
0x80n0:13 [ } 157] = 300
5.6.6 Calibration
Vendor calibration, index 0x80n0:0B [
}
157]
The vendor calibration is enabled via index 0x80n0:0B [
}
157] . Parameterization takes place via the indices
• 0x80nF:01 [ } 159]
Thermocouple offset (vendor calibration)
• 0x80nF:02 [
}
159]
Thermocouple gain (vendor calibration)
• 0x80nF:03 [ } 159]
Reference point offset [Pt1000] (vendor calibration)
• 0x80nF:04 [
}
159]
Reference point gain [Pt1000] (vendor calibration)
Vendor and user calibration
User calibration (index 0x80n0:0A [
}
157] ) should only be performed instead of the vendor calibra-
tion (index 0x80n0:0B [ } 157] ), but this is generally only necessary in exceptional cases.
