Disabling the
Input Protect
Feature
(optional)
Disabling the Input Protect feature voids the HP E1415’s warranty. The Input
Protect feature allows the HP E1415 to open all channel input relays if any input’s
voltage exceeds
±
19 volts (
±
6 volts for digital I/O SCPs). This feature will help to
protect the card’s Signal Conditioning Plug-ons, input multiplexer, ranging
amplifier, and A/D from destructive voltage levels. The level that trips the
protection function has been set to provide a high probability of protection. The
voltage level that is certain to cause damage is somewhat higher. If in your
application the importance of completing a measurement run outweighs the
added risk of damage to your HP E1415, you may choose to disable the Input
Protect feature.
Voids Waranty!
Disabling the Input Protection Feature voids the HP E1415’s warranty.
To disable the Input Protection feature, locate and cut JM2202. Make a single cut in
the jumper and bend the adjacent ends apart. See following illustration for location
of JM2202.
Disabling
Flash Memory
Access
(optional)
The Flash Memory Protect Jumper (JM2201) is shipped in the “PROG” position.
We recommend that you leave the jumper in this position so that all of the
calibration commands can function. Changing the jumper to the protect position
will mean you won't be able to execute:
•
The SCPI calibration command CAL:STORE ADC | TARE
•
The register-based calibration commands STORECAL, and STORETAR
•
Any application that installs firmware-updates or makes any other
modification to Flash Memory through the A24 window.
With the jumper in the “PROG” position, you can completely calibrate one or more
HP E1415s without removing them from the application system. An HP E1415
calibrated in its working environment will in general be better calibrated than if it
were calibrated separate from its application system.
The multimeter you use during the periodic calibration cycle should be considered
your calibration transfer standard. Have your Calibration Organization control
unauthorized access to its calibration constants. See the HP E1415 Service Manual
for complete information on HP E1415 periodic calibration.
If you must limit access to the HP E1415's calibration constants, you can place
JM2201 in the protected position and cover the shield retaining screws with
calibration stickers. See following illustration for location of JM2201.
