4-32 System Configuration 879596 TempScan / MultiScan User's Manual
Power-Up Configuration
The TempScan/1100 or MultiScan/1200 unit has an internally-stored factory-default configuration which
can be recalled at any time. You can program the unit to power-up in a user-defined state, or if preferred,
you can configure the unit to power-up with the default configuration.
During normal operations, the factory defaults may be recalled by issuing the Restore Factory Defaults
(
*F) command. When this command is processed, the TempScan/1100 or MultiScan/1200 will load the
factory default configuration and will operate accordingly. However, this command may not be issued
while an acquisition is currently configured.
The TempScan/1100 or MultiScan/1200 unit is normally configured to power up with the last known
configuration at the time that it was powered down, or at the time that the Reset Power-On (
*R) command
is issued. However, the unit may be configured to always power-up either under the factory default
configuration or under the last-known configuration, via the Set Power-Up Configuration (
*S) command.
Note:
Configuring the TempScan/1100 or MultiScan/1200 master unit to power up under the
factory defaults or recalling the factory default settings will not affect pre-existing calibration
factors of the master unit or its slave units.
The following list describes the execution steps and effects when the TempScan/1100 or MultiScan/1200 is
configured to power up under the factory default configuration:
Step 1:
Q7,0,0,0,0. Using the Set Query Terminator (Q) command, set the general response
terminator to
CR-LF/EOI. Set all other terminators to None.
Step 2:
V0. Using the Set User Terminator (V) command, set the user terminator to ASCII
hexadecimal value
00, or NUL.
Step 3:
F0,0. Using the Set Data Format (F) command, set the data format to Engineering Units,
Degrees Celsius.
Step 4:
M0. Using the Set SRQ Mask (M) command, set the SRQ Mask to 000.
Step 5:
N0. Using the Set Event Mask (N) command, set the Event Status Enable Register (ESE) to
000.
Step 6:
*C. Using the Clear Channel Configuration (*C) command, clear all channel configurations.
Step 7:
Y0,0,0. Using the Set Counts (Y) command, set all acquisition counts to 0.
Step 8:
I00:00:00.0,00:00:00.0. Using the Set Scan Interval (I) command, set both timebase
intervals to 0 seconds, or fast mode.
Step 9:
L1,0,0. Using the Set Trigger Level (L) command, clear the trigger level configurations.
Step 10:
T0,0,0,0. Using the Set Trigger Configuration (T) command, clear the acquisition trigger
configurations.
Step 11:
M#0. MultiScan/1200 only. Using the Set Measuring Mode (M#) command, set the
measuring mode to line-cycle integration/high-speed multi-channel mode.
Step 12:
F#20000.0. MultiScan/1200 only. Using the Set Burst Mode Frequency (F#) command,
set the burst mode frequency to 20 kHz.
Step 13:
W#32. MultiScan/1200 only. Using the Set Averaging Weight (W#) command, set the
sampling weight to 32.
