IL_H, IL_H? – Upper Limit Value for Current Setting
Menu
Function
IL_H defines the upper setting limit (soft-limit) for current setpoint
value Iset.
The limit can be used to assure that output current is not
inadvertently set above a specified value.
The IL_H command corresponds to the ILIM command for the
SSP6XN Konstanter series as an upper limit value.
Thus
IL_H
can also be replaced with
ILIM
.
When the
ILIM?
query is executed,
IL_H +XXX.XXX
is
returned in response.
Values outside of the value range (Iset

w

Inom) are not
accepted, and cause generation of an error message and setting
of an error bit in event register ERC.2.
Inom is device-specific maximum nominal current.
Entered numeric values are rounded off to device-specific
resolution.

Comments
The IL_H function is not active for setting output current by means
of control signal Iext via the analog interface.
IL_L, IL_L? – Lower Limit Value for Current Setting
Menu
Function
IL_L defines the lower setting limit (soft-limit) for current setpoint
value Iset.
The limit can be used to assure that output current is not
inadvertently set below a specified value.
Values outside of the value range (0

w

Iset) are not accepted,
and cause generation of an error message and setting of an error
bit in event register ERC.2.
Inom is device-specific maximum nominal current.
Entered numeric values are rounded off to device-specific
resolution.

IMAX? – Maximum Measured Current Value
Menu
Function
The IMAX function reads out the highest output current value
which was measured by the Iout measuring function and saved to
Min-Max memory while the MINMAX function was set to ON.
If the measured current value has exceeded the measuring range
limit at least once with the MINMAX function set to ON, “+OL”
appears at the display for IMAX and “+999999.” is entered to the
data string.
The Min-Max memory value can be reset to the momentarily
measured value with
MINMAX RST
(for all 4 parameters at once).
Query Command
Syntax:
IMAX?
Sample response string:
IMAX +XXX.XXX
IMIN? – Minimum Measured Current Value
Menu
Function
The IMIN function reads out the lowest output current value which
was measured by the IOUT measuring function and saved to
Min-Max memory while the MINMAX function was set to ON.
If the measured current value has fallen below the measuring
range limit at least once with the MINMAX function set to ON,
“–OL” appears at the display for IMIN and “–999999.” is entered
to the data string. The Min-Max memory value can be reset to the
momentarily measured value with MINMAX RST (for all 4
parameters at once).
Query Command
Syntax:
IMIN?
Sample response string:
IMIN +XXX.XXX
IOUT? – Querying the Momentary Current Value
SELECT B
Function
The IOUT? function reads out the momentary measured value for
output current.
The upper range values may change minimally after balancing!
If the measuring range is exceeded or fallen short of, “+/–OL” is
displayed or “+/–999999” is entered to the data string.
Query Command
Syntax:
IOUT?
