Specifications

·
The <sub_type> parameter: values of 85 and 92 differentiate between 100 W
(@ 0 °C) RTDs with temperature coefficients of 0.00385 and and 0.00392
ohm/ohm/°C respectively. The <sub_type> values of 2250, 5000, and 10000 refer
to thermistors that match the Omega 44000 series temperature response curve.
These 44000 series thermistors are selected to match the curve within 0.1 or
0.2 °C. For thermistors, <sub_type> may be specified in kW (kohm).
The <sub_type> EEXTended applies to E type thermocouples at 800 °C and
above.
CUSTom is pre-defined as Type K, with no reference junction compensation
(reference junction assumed to be at 0 °C).
·
The *CAL? command calibrates temperature channels based on Current Source
SCP and Sense Amplifier SCP setup at the time of execution. If SCP settings are
changed, those channels are no longer calibrated. *CAL? must be executed again.
·
See “Linking Input Channels to EU Conversion” on page 57 for more
information.

When Accepted: Not while INITiated

Usage Link two channels to the K type thermocouple temperature conversion
SENS:FUNC:TEMP TCOUPLE,K,(@101,102)

[SENSe:]FUNCtion:TOTalize
[SENSe:]FUNCtion:TOTalize <ch_list> sets the SENSe function to TOTalize for
channels in <ch_list>.

Comments
·
The totalize function counts rising edges of digital transitions at
Frequency/Totalize SCP channels. The counter is 24 bits wide and can count up to
16,777,215.
·
The SENS:TOT:RESET:MODE command controls which events will reset the
counter.
