LIQ-MAN-1066
Procedure
Follow the Reset Analyzer procedure (
Section 7.8
) to reconfigure the transmitter to display new
measurements or measurement units. To change the specific measurement or measurement
units for each measurement type, refer to the Program menu for the appropriate measurement
(
Section 6.0
).
Choosing Temperature units and
automatic/Manual Temperature Compensation
Purpose
Most liquid analytical measurements (except ORP and Redox)
require temperature compensation. The 1066 performs tempera-
ture compensation automatically by applying internal temperature
correction algorithms. Temperature correction can also be turned
off. If temperature correction is off, the 1066 uses the temperature
entered by the user in all temperature correction calculations.
Configuring and Ranging Current Outputs
Purpose
The 1066 has two analog current outputs. Ranging the outputs means assigning values to the
low (4 mA) and high (20 mA) outputs. This section provides a guide for configuring and ranging
the outputs. ALWAYS CONFIGURE THE OUTPUTS FIRST.
Definitions
1. CURRENT OUTPUTS. The transmitter provides a continuous output current (4-20 mA)
directly proportional to the process variable or temperature. The low and high current out-
puts can be set to any value.
2. ASSIGNING OUTPUTS. Assign a measurement or temperature to Output 1 or Output 2.
3. DAMPEN. Output dampening smooths out noisy readings. It also increases the response
time of the output. Output dampening does not affect the response time of the display.
4. MODE. The current output can be made directly proportional to the displayed value (linear
mode) or directly proportional to the common logarithm of the displayed value (log mode).
Procedure: Configure Outputs
Under the Program/Outputs menu, the adjacent screen will
appear to allow configuration of the outputs. Follow the menu
screens in
Figure 7-1
to configure the outputs.
