Reference Section: Initialization Mode (INIt)
Navigate to the installed thermocouple type. Supported types are as follows:
• k – Type K (factory default)
• J – Type J
• t – Type T
• E – Type E
• N – Type N
• R – Type R
• S – Type S
• b – Type B
• C – Type C
Select the indicated type.
4.1.2 Resistance Temperature Detector (RTD) Input Type (INIt >
INPt > Rtd)
Select Rtd as the input type. Factory default configuration settings are three-wire, 100 Ω,
using the European standard 385 curve. Note that the 392 and 3916 curves are only available
for 100 Ω RTDs. If Rtd is selected and a specific configuration is not changed, the last saved
configuration will be used.
Navigate to the desired configuration parameter:
• N.wIR – Firmware selection of the number of wires for RTD connection (no jumpers
needed)
• A.CRV – Calibration curve covering both the international standard and the
resistance of the RTD
Select the option.
4.1.2.1 Number of RTD Wires (INIt > INPt > Rtd >
N.wIR)
Navigate to the desired setting. Settings include the following:
• 3 wI – Three-wire RTD (factory default)
• 4 wI – Four-wire RTD
• 2 wI – Two-wire RTD
Select the indicated option.
4.1.2.2 Calibration Curve (INIt > INPt > Rtd > A.CRV)
Navigate to the desired setting. Settings include the following:
• 385.1 – European and most common standard at the conventional
resistance of 100 Ω (factory default)
• 385.5 – European curve for 500 Ω
• 385.t – European curve for 1000 Ω
• 392 – Old US standard (rarely used), at 100 Ω only
• 3916 – Japanese standard, at 100 Ω only
