Store and Recall
STO (store) and RCL (recall) allow up to 9
complete instrument setups to be saved. To store a
setup, press the STO key, followed by a number (1-
9) and then the ENTER key. To recall a setup,
press the RCL key, followed by a number (0-9) and
then the ENTER key. RCL 0 returns the setup to
the factory default. Whenever a setup is recalled,
the high voltage is turned off for safety. If an 'Err3'
(recall error) occurs, then that stored setup was lost
due to a memory error and must be re-entered.
Error Messages
The following error messages may appear in the
center display. The CLR key clears the errors.
Err1 Memory Error
Power on memory error of the unit's
last setup. Default setup is recalled.
Err2 Illegal Parameter Entered.
Err3 Stored Value Recall Error
The stored setup (from STO and
RCL) was lost.
Err4 Illegal Storage Address
STO 0 is reserved for default settings.
Err5 No GPIB Interface The unit does
not have the GPIB option so the
GPIB address cannot be set.
Err6 Syntax error over GPIB.
Err7 Illegal parameter entered over GPIB.
Parameter entered is out of range.
Err 8 GPIB Output queue full.
Analog Programming and Monitor
The rear panel voltage select switch determines
whether the output voltage is set from the front
panel or from the rear panel voltage input. If the
switch is in the MON (monitor) position, the front
panel will set the voltage. If the switch is in the
SET position, the rear panel voltage will set the
output voltage. When the switch is in the SET
position, the REAR (rear panel) LED is lit and the
output voltage being set by the rear panel is
displayed in the middle display when it is showing
VOLTAGE SET. The voltage limit is still active
and does not allow the rear panel voltage to set the
output above the voltage limit. If the rear panel
voltage is too high, the output voltage will stop at
the limit voltage.
Voltage Monitor/Set: When the Analog
Programming switch is in the MONITOR position,
the VOLTAGE BNC is a monitor output providing
0 to +10 Volts for 0 to full scale output regardless
of polarity. When the switch is in the SET position,
the BNC becomes an input over the same range.
An input of 0 to +10 Volts will program the high
voltage from 0 to full scale, regardless of polarity.
Current Monitor: This provides 0 to +10 Volts
out for 0 to full scale output regardless of the
output polarity.
If the switch position is changed while the high
voltage is on, the unit will shut the high voltage
off.
Default Setup
The factory default setup can be recalled by
pressing the CLR key while turning the unit on or
recalling setup 0 (RCL 0). The default setup is also
recalled after a power on memory error (ERR 1).
