Kepco EL NV RAM Load Save, Clear and Restore Utility

This utility allows the user to save, clear and restore data stored in EEPROM (Electrically Erasable Programmable Read-Only Memory), the non-volatile memory (referred to as NV RAM) of Kepco's EL Series Electronic Loads.

The EL Series uses two (2) types of memory to store customer data within the processor chip. The processor chip contains a volatile Random Access Memory (RAM) and a Flash (EEPROM) Memory. The Flash memory is divided into regions, Program Memory, and Variable and Settings memory. Power cycling the EL will erase all data stored in RAM memory during the power up self test. However, Flash memory must be erased or reset to the original manufacturing state by using NV RAM Load Save, Clear and Restore Utility. The EL Series uses EEPROM to store the unit's identity, calibration constants, front panel settings and certain other operating parameters. Though the command sequences for storing this information are not published, clearing NV RAM guards against the possibility that this data can be changed in the field by a sophisticated or properly trained individual.

NOTE: The NV RAM Save, Clear and Restore features will not function until it is enabled. It is enabled at time of order by requesting a Certificate of Volatility. If not requested at time of order, contact Kepco application support to order a Certiifcate of Volatility and receive the instructions to enable the feature.

Instructions for installation and use of this utility are found in the NV RAM Save, Clear and Restore Instruction Manual, available via free download
