Option Description
HOLD(default) Holds the outputs at the last known value when an error occurs or
measurements are stopped (e.g., calibration, rinse, reactivation or grab sample
measurement).
TRANSFER Sets the outputs to the transfer value when an error occurs or measurements
are stopped (e.g., calibration, rinse, reactivation or grab sample
measurement).

Description
NONE (default)—Sets the output to disabled. [analyzer name]—Sets the
output to enabled. Selects the channel represented at the output.
Note: The channels that are followed by an asterisk (*) are disabled.
Sets the low measurement value that is represented as 4 mA at the
analog output (default: 0.000).
Sets the high measurement value that is represented as 20 mA at the
analog output (default: 1.000).
Sets the value at the selected output when an error occurs if the ERROR
HOLD MODE setting is set to TRANSFER OUTPUTS (default: 4 mA).
Sets the amount of time for analog output averaging (default: 0 seconds).
For example, if the value is set to 30 seconds, the value of the analog
outputs is updated every 30 seconds and the value is the average of the
analog output values during the previous 30 seconds.
Sets the HART address for the selected output channel. Range 0 (default)
to 63.
Description
Calibrates the low (4 mA) and high (20 mA) values for each of the three
4-20 mA outputs (A, B, C).
Adjust the DAC counts until a connected multimeter reads the
applicable output value. The default DAC counts are:
• Output A—2807 for 4 mA, 14046 for 20 mA
• Output B—2797 for 4 mA, 14109 for 20 mA
• Output C—2641 for 4 mA, 13294 for 20 mA
HOLD—Holds the selected output at the last known value. TRANSFER
—Sets the selected output to the transfer value. RELEASE (default)—
Lets the selected output continue to represent the measured value.
