Check the bottom-most
Monitor
box to automatically show the present step and status of the sequence. The Step buttons will
depress to indicate the current step of the sequence.
Update All
synchronizes the data from all channels, reads the calibration data, updates all channel settings, and updates the
monitored values once for all channels. This function also appears on the
Manual Power Supply Control Panel
.
Channel Sequence Control Panels
The Channel Sequence panels (
Figure 19
shows one for Channel A) let you monitor the progress of each particular channel
during an automated run. Click Sequencer A–H in the left pane to open the control panel for that channel.
Figure 19. Sequencer Channel A Sequence Monitor and Control Panel
If Monitoring is on for this channel (as set in the
Sequencer Control Panel
), the
Measurements
,
Run Status
, and
Errors
fields will
show the channel’s last measured voltage and current values, status, and encountered errors. Click
Update
to refresh the values.
Check the
Continuously
Monitor Measurements
box to update the values on a continual basis.
The
Navigate Programs
drop-down menu shows the channel programs. Select a program to view its contents in the right pane.
Error Reporting/Break Settings
The HVS448 channels continuously check the validity of their settings. In response to invalid conditions, each channel can stop its
sequence. You can control which errors will stop a sequence by clicking the
Break on…
button. The
Stop the sequence on:
dialog
box will be displayed (
Figure 20
). These controls are similar to the
Error Reporting/Trip Settings
controls in manual mode, but
here the settings determine whether a channel sequence will be stopped (rather than determining when a channel will clip or
trip). If selected, an error will cause an “Exit” instruction to be executed by the sequencer. See
Exit
.
Figure 20. ”Stop the sequence on:” Dialog Box
The possible errors conditions are:
-
Numerical Exception
: Overflow/underflow in a mathematical calculation (e.g., square root of a negative number was
attempted)
-
Current at limit
: The current exceeds the channel limits
-
Voltage at limit
: The voltage exceeds the channel limits
