5.2 RETURNING PRODUCTS TO LAKE SHORE
If it is necessary to return the Model 211 or accessories for recalibration,
repair or replacement, an RGA number must be obtained from a factory
representative or from the Lake Shore web site. Do not return a product
to Lake Shore without an RGA number. The following information must
be provided to Lake Shore in order to obtain an RGA number.
1. Instrument model and serial number.
2. User name, company, address, phone number, and e-mail address.
3. Malfunction symptoms.
4. Description of the system in which the product is used.
If possible, the original packing material should be retained for reshipment.
If not available, a minimum of three inches of shock adsorbent packing
material should be placed snugly on all sides of the instrument in a sturdy
corrugated cardboard box. Include the RGA number on the mailing label or
written prominently on the outside of the box. Include a copy of the
customer contact information and RGA number inside the box. Consult
Lake Shore with questions regarding shipping and packing instructions.
5.3 ERROR MESSAGES
The following messages appear on the instrument display when it identifies
a problem during operation. The messages are divided into two groups.
Instrument hardware messages are related to the instruments internal
circuits or non-volatile memory. If one of these messages persists after
power is cycled the instrument requires repair or recalibration. Limit
messages are most often associated with over voltage conditions caused by
an improperly selected range or excessive noise on the measurement leads.
If these messages persist after the input or output is configured properly, the
instrument may require repair.
5.3.1 Instrument Hardware Errors
Err 01 Indicates that there is a hardware problem in the instrument
memory. This error is not correctable by the user and the
factory should be consulted.
Err 02 Indicates there is a soft error in the instrument memory. This
error can be corrected reinitializing memory. Reinitializing
memory sets the instrument to defaults and erases the user
curve. To reinitialize the memory after an Error 02, press both
the s and t keys simultaneously. The display will blank for
about 5 seconds while the memory is initialized.
