Note: If a self•
ZERO
determination is performed on an active signal
exceeding the maximum permitted setpoint value for
ZERO
(see
User•defined
ZERO
setpoint), the maximum setpoint value is assigned
and the message SIG 1 (or 2) ZERO TOO HIGH is displayed.
User-defined
ZERO
setpoint
If the self•
ZERO
setpoint value determination is not appropriate for a
particular application, any value from -830000.0 through 830000.0
may be entered at the keyboard.
Entering a value less than the self•
ZERO
value shifts background
baseline upward (but at the expense of available output range); for
example, to capture negative peaks, or to compensate for negative
baseline drift.
Signal attenuation
Analog signal output levels (+1 mV or +1 V outputs) for either signal
channel (controlled by
SIG 1
, and by
SIG 2
if Option 550/Accessory
19242A or Option 560/Accessory 19254A is installed) are attenuated via
RANGE 2 ()
and
ATTN 2 ()
.
For
RANGE 2 ()
, each step to a higher setpoint value decreases the output
signal level by a factor of 2 (half the previous level). Also,
RANGE 2 ()
affects signal level at both the +1 V and +1 mV analog outputs.
+1 V Output Level =
Signal
2
RANGE 2 ()
ATTN 2 ()
affects only the +1 mV analog output: each step to a higher
value reduces the output signal level (as defined by
RANGE 2 ()
) by half.
+1 mV Output Level =
