Settings
The following dialog box appears when you choose
Setup
and
Params
, and
then double-click the channel that you want to set.
Channel
: Select ENABLE to record with this channel, or select DIS-
ABLE not to record with this channel.
Range : Select the input range.
Sample Frequency : You can select 10 times the Base Sample Freq
when you turn on
Multi Sampling
check box.
Channel Name
: You can name the channel. Use up to 16 alphanumeric
characters.
Filter : Select the filter cutoff frequency.
PA
: Select the sensor power supply. Set to
OFF
in DC mode.
All Pa Amp Same Condition
: When this option is selected, the same
parameters are set for all signal conditioners of the same type.
▼
DC mode: Not supply power to the sensors.
PA mode: supplies power to the sensors.
▼
When you record in the PA mode for the first time
after power-on, or when you switch from the DC
mode to the PA mode, leave the unit in the Rec
Standby mode for about one minute before Rec
Start to stabilize the amplifier.
▼
Enable both channels of a slot.
▼
Filter cutoff frequency is set slot by slot, not channel
by channel.
