iTEMP TMT71/72 Operating menu and parameter description
Current trimming 4 mA
Navigation Application → Current output → Current trimming 4 mA
Description Use this function to set the correction value for the current output at the start of the
User entry 3.5 to 4.25 mA
Factory setting 4 mA
Additional information The trimming only affects the current loop values from 3.8 to 20.5 mA. The failure mode
with low alarm and high alarm current values is not subject to trimming.
Current trimming 20 mA
Navigation Application → Current output → Current trimming 20 mA
Description Use this function to set the correction value for the current output at the end of the
measuring range at 20 mA.
User entry 19.50 to 20.5 mA
Factory setting 20.000 mA
Additional information The trimming only affects the current loop values from 3.8 to 20.5 mA. The failure mode
with low alarm and high alarm current values is not subject to trimming.
Damping
Navigation Application → Current output → Damping
Description Use this function to set the time constant for current output damping.
User entry 0 to 120 s
Factory setting 0 s
Additional information The current output responds to fluctuations in the measured value with an exponential
delay. The time constant of this delay is defined by this parameter. If a low time constant is
entered, the current output responds quickly to the measured value. On the other hand,
the response of the current output is delayed if a high time constant is entered.
