Cryomagnetics Model 4G Operating Instruction Manual 26
Five current ranges may be defined by setting the upper current limits (“To” field) for each limit.
Start at the top and work down. After a value is entered for the upper limit of a range, it is
automatically copied to the beginning of the next range. The upper limit must be greater than the
beginning of the range or else a 'VALUE TOO LOW' error will appear.
Sweep Rates
Sweep rates may be set for each current range. This allows sweep rates to be automatically
reduced at high fields and increased at low fields if desired.
Fast Mode
Fast mode sweep rate is used when sweep up fast [Shift-HI LIMIT], sweep down fast [Shift-LO
LIMIT], or [Shift-Zero] is selected. These modes are selected by holding the shift key and pressing
the appropriate sweep button. Fast mode is only available when the persistent switch heater option
is enabled, and the heater is turned off.
