4. Recalibrate the flowmeter:
a. Perform the flow calibration procedure described in
Section 8.2
,
page 73.
b. Perform the density calibration procedure described in
Section 14.4
, page 138.
c. Perform the viscosity calibration procedure described in
Section 14.5
, page 148.
14.6 Milliamp output trim
Milliamp output trim adjusts the transmitter digital-to-analog converter to
match milliamp outputs with a specific reference standard, receiver, or
readout device.
Preparing for milliamp
output trim
For trimming, milliamp outputs require a reference device such as a
digital multimeter (DMM). To trim the milliamp output, connect the
reference device to the transmitter terminals listed in
Table 14-5
, then
perform the milliamp output trim procedure as described below.
If HART over Bell 202 is being used, and the output being trimmed is the
primary milliamp (mA) output, connect the reference device to the
transmitter as shown in
Figure 14-13
.
