parameter below.
mV Zero 1
Set the Cell simulator millivolt source to –20mV and allow the display to
stabilize.
mV Span 1
Set the Cell simulator millivolt source to 180mV and allow the display to
stabilize.
mV Zero 2
Set the Temperature simulator millivolt source to 10mV and allow the display to
stabilize.
mV Span 2
Set the Temperature simulator millivolt source to 40mV and allow the display to
stabilize.
Adjust Cold Junction Value
Set the measured ambient temperature in
°
C
Adjust RTX Zero
Set the milliammeter reading to the minimum retransmission level determined by
the
Retransmission Type
setting – see Section 7.6. For example, when the
Retransmission Type
is set to
4
–
20
, adjust the milliammeter reading to 4mA.
Adjust RTX Span
Set the milliammeter reading to the maximum retransmission level determined
by the
Retransmission Type
setting – see Section 7.6. For example, when the
Retransmission Type
is set to
4
–
20
, adjust the milliammeter reading to 20mA.
