C30 Release
Overview
No hardware modifications or recalibration issues are required.
Upgrade Considerations for Models 2400,2410,2420,2425,2430,2440
Installation Instructions
After obtaining the Flash program and the Firmware file, unzip the files in a folder of your choice
and run the "setup.exe" program. Follow the instructions to install the program. When the
installation is complete, launch the program from your Windows Start menu under
Programs/Keithley Instruments. The Application support staff will also provide the file for the
latest firmware revision. Put that file in a folder where you can find it and then run the Flash
Wizard32 program. The program will autodetect the instrument and request you to specify the
firmware file.
It is recommended to put the instrument on a UPS to avoid possibility of the instrument losing
power during the upgrade process,
Either GPIB or RS-232 communications can be used to perform the upgrade. GPIB will be
significantly faster. The upgrade only takes several minutes using the GPIB.
Contact the Keithley Applications team if you have any questions or concerns about upgrading.
Critical Fixes
PR28880 Models Affected:2400,2410,2420,2425,2430,2440
Symptom:
When the OVP is flickering on the display, the unit “Locks up” or times out on the
GPIB. OVP can be caused by electrically noisy environments.
Resolution:
Unit will no longer lock up the GPIB or the instrument.
PR24684 Models Affected:2400,2410,2420,2425,2430,2440 and all “C” versions
Symptom:
When using the Offset Compensation ohms math function, displays “Not a Num”
Resolution:
This issue is resolved.
Enhancements
There are no Enhancements with this release
Non-critical Fixes
PR25266 Models Affected: 2420,2425,2430,2440
Symptom:
Autorange in current mode only does not downrange when appropriate.
Resolution:
This issue is resolved.
C29 Release
Overview
C29 was not released.
C28 Release
Overview
C28 was only released for Model 2420 to implement corrections for internal manufacturing
issues. No hardware modifications or recalibration issues are required.
C27 Release
Overview
No hardware modifications or recalibration issues are required.
Critical Fixes
PR22327 Models Affected: 2400,2410,2420,2425,2430,2440 and all “C” versions
Symptom:
If using the *SRE register, the MAV bit is reported incorrectly in the RS-232
communication. This will lead to the SRQ not generated.
Resolution:
This issue is resolved
PR23912 Models Affected: 2400,2410,2420,2425,2430 and all “C” versions
Symptom:
In the 488.1 mode, the unit can lock up the bus if using external trigger and addressed
to talk. If the trigger hasn’t occurred, the unit will time out. The BUS will not respond
again until the unit is power recycled.
Resolution:
This issue is corrected.
Enhancements
There are no Enhancements with this release
Non-Critical Fixes
PR23012 Models Affected: 2400,2410,2420,2425,2430,2440 and all “C” versions
Symptom:
From front panel operation only: the Current source delay is limited to changes in the
100uS resolution, whereas the voltage source delay can be changed within 10uS.
Both delays should be configurable to within 10uS resolution.
Resolution:
This issue is corrected.
PR23886 Models Affected: 2400,2410,2420,2425,2430,2440 and all “C” versions
Symptom:
Transients occur between steps in the custom sweep when the instrument switches
configuration from a voltage source to a current source.
Resolution:
This issue is corrected.
Models Affected: 2430,2430-C
Symptom:
The Source Output trigger could have delay (<1mS) between the output trigger and
the pulse.
Resolution:
The Source output trigger now occurs at the same time as the pulse output.
Models Affected: 2430-C
Symptom:
Unit locks up when the contact check reports a failure in the pulse mode with auto
source auto clear enabled. Requires a power recycle.
Resolution:
This issue is corrected.
C26 Release
Overview
No hardware modifications or recalibration issues are required.
Critical Fixes
PR20014 Models Affected: 2400,2410,2420,2425,2430,2440 and all “C” versions
Symptom:
While Compliance Range Sync feature is enabled, incorrect current measurement are
possible, the value may be off by orders of magnitude.
For example, the displayed reading is 100.05 mA instead of the expected 100uA.
Resolution:
This was introduced in C24 when the Compliance Range Sync feature was
introduced. This issue is corrected.
PR20130 Models Affected: 2400,2410,2420,2425,2430,2440 and all “C” versions
Symptom:
Range hold delay feature causes incorrect output voltages when the voltage source
range is increased. For example, when increasing the instrument’s output from 0 volts
(200mV range) to 7 volts (10 volt range), the output is at 0.2volts instead of 7.
Resolution:
This issue is corrected.
Enhancements
PR21121 Models Affected: 2400,2410,2420,2425,2430,2440 and all “C” versions
Enhancement:
Simplified front panel bi-polar sweep capability for Log and Stair sweeps. Did not have
the ability to change polarity without the use of the sign key. C26 changed the
configuration sweep menus to allow editing the sign of the values without having to
use the sign key.
Custom sweep not affected by enhancement. Still requires the use of the sign key.
PR19965 Models Affected: 2400,2410,2420,2425,2430,2440 and all “C” versions
Enhancement:
Add ability to have the current measure range temporarily go to the compliance during
a source memory sweep.
It is desired to have the current measure range go to the compliance range temporarily during a
source memory sweep, then go to the desired measure range. This is so any current transients
due to cable capacitance can go away quickly at the higher compliance range, but then be able to
take a reading on the lower measure range. Otherwise, need to requires a long delay before a
reading or a higher measure range.
PR19966 Models Affected: 2400,2410,2420,2425,2430,2440 and all “C” versions
Enhancement:
Add ability to do source memory branching on both pass and fail.
It is desired to have the ability to do source memory branching on both passing and failing limits.
Previous to C26, it was only possible to do one or the other when evaluating limits.
PR21051 Models Affected: 2400,2410,2420,2425,243,2440 and all “C” versions
Enhancement:
In keeping with the new nomenclature for the output enable ( previously referred to as
the INTERLOCK), the following commands were added.
:OUTPut[1]:ENABle[:STATe] ON|OFF and :OUTP1:ENABle:TRIPped
PR21206 Models Affected: 2400,2410,2420,2425,2430,2440 and all “C” versions
Enhancement:
Model 6430 code is removed from the 2400 series code to become it’s own code
base.
Non-Critical Fixes
PR22599 Models Affected:2400,2410,2420,2425,2430,2440 and all “C” versions
Symptom:
Binary data transfer delivers sometimes more data than expected
Resolution:
This issue is corrected.
