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

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.
