SECTION
AOUT CALIBRATED
Initiates a calibration of the A1, A2 and A4 analog output channels that
determines the slope and offset inherent in the circuitry of each output.
These values are stored in the and applied to the output signals by the CPU
automatically
5.10.1.1
CONCOUT_1
1
Sets the basic electronic configuration of the A1 output. There are four
options:
RANGE: Selects the signal type (voltage or current loop) and level of the
output
A1 OFS: Allows them input of a DC offset to let the user manually adjust
the output level
AUTO CAL: Enables / Disables the AOUT CALIBRATION Feature
CALIBRATED: Performs the same calibration as AOUT CALIBRATED,
but on this one channel only.
CONCOUT_2
1
Sets the basic electronic configuration of the A2 output. There are three
options:
RANGE: Selects the signal type (voltage or current loop) and level of the
output
A2 OFS: Allows them input of a DC offset to let the user manually adjust
the output level
AUTO CAL: Enables / Disables the AOUT CALIBRATION Feature
CALIBRATED: Performs the same calibration as AOUT CALIBRATED,
but on this one channel only.
5.10
TEST OUTPUT
1
Sets the basic electronic configuration of the A4 output. There are three
options:
RANGE: Selects the signal type (voltage or current loop) and level of the
output
A4 OFS: Allows them input of a DC offset to let the user manually adjust
the output level
AUTO CAL: Enables / Disables the AOUT CALIBRATION Feature
CALIBRATED: Performs the same calibration as AOUT CALIBRATED,
but on this one channel only.
5.10.1.9
AIN CALIBRATED
Initiates a calibration of the A-to-D Converter circuit located on the
Motherboard.
5.10.2
XIN1
.
.
.
XIN8
For each of 8 external analog inputs channels, shows the gain, offset,
engineering units, and whether the channel is to show up as a Test
function.
1
Changes to RANGE or REC_OFS require recalibration of this output.
