2.10 Measurement Function
The electronic load has measurement system with high resolution. The input current level and voltage level can be measured in real
time. The input power level and resistance level can be computed with the input voltage level and current level. Each measured value
can be checked through LCD display or via remote command (MEASure).
2.11 Saving and Recalling
The electronic load is provided with an EEPROM memory, which can save various parameters, such as modes, input status, current,
voltage, resistance, transient settings, limits, etc.
SPL Series electronic load can save 10 groups of parameters.
All parameters relevant to saving and recalling operation are listed in List 2-1.
The 10 groups of parameters stored in Location 0~9 can be saved and recalled by pressing
key + key and key +
key, or via the remote command (*SAV < NRl > and *RCL < NRl >).
The parameter saved in Location 0 will be recalled automatically every time the load is turned on.
List 2-1
* indicates it only can be programmed in the remote control.
2.12 Reading Remote Programming Errors
The Err indicator will be turned on when remote programming errors occur. The error codes are shown as followings:
Remote programming errors can be checked by pressing key after pressing key on the front panel. The remote command
(SYSTem:ERRor?) can read back the error codes and error messages when it is in remote control.
