TempScan / MultiScan User's Manual

Note:

When using a channel as a reference channel, remember that lower numbered channels
are calculated ahead of higher numbered channels, e.g., CH1 is calculated ahead of CH2.
This makes a difference when subtracting a reference channel in regard to the time aspect
of the reference value.

If the channel is configured for Volts,

 the units automatically change to V; at this point you have

the option of selecting the millivolt unit (mV).  The user can also change each channel to apply a
linear equation (

mX+b

) to the data.  When the 

mX+b

 option is selected the Configure Engineering

Units dialog box is displayed. You are prompted to define “

m

” and “

b

” and the engineering units

label; as well as which standard units the 

mX+b

 equation should be applied to. The engineering

units chosen will be displayed in the “Units” column, and the “

mX+b

” equation will be applied to

the reading from the device before the reading is displayed or written to disk.

The 

mX+b

 option is convenient for obtaining a value which has a linear relation to a channel

reading.

X

 is the scanned voltage value read back from the acquisition device

m

 is [but not limited to] a 

proportionality constant

 or 

gain factor, 

but not zero

.

b

  is the 

offset value

 (the value of the calculated reading when the scanned value is “zero”).

Alarm Configuration Columns

1.

Low Limit

 

 Set alarm low limit.

2.

High Limit

 

 Set alarm high limit.

3.

Hysteresis

 

 A hysteresis value can be set for each channel to avoid a “chatter” problem.

4.

Alarm # 

  You can assign one alarm number (1 to 32) to a channel.  Any number of channels

can be assigned to the same alarm number.  A given digital output will be set “true” (1) if at least
one of the common channels (assigned to a single alarm) enters an alarm state.

Acquisition Setup Dialog Box

The information entered in the Acquisition Setup dialog box is used by the Arm Acquisition command
to set up the acquisition of data to disk.  When the trigger is satisfied, the scans are collected at the
selected scan frequency and stored to disk in the designated file.

The Acquisition Setup dialog box can be accessed in one of three ways: a) clicking on the Channel
Configuration button (item 8 in Main Window figure), b) clicking on the Acquisition Setup tab from
the Channels or Data Destination dialog boxes, c) using the Setup pull-down menu and selecting

Acquisition
