AXIOMET AX-EL300W60A [11/72] Main function

Under remote control status, the REM annunciator is turned on, all operations on front panel keypad and

knobs become invalid (except “Lock/Local” key). All operations on electronic load are controlled by remote

controller. The electronic load will return to local control and REM remote control annunciator is turned

off after receiving the return command (e.g. : SYST:LOC). Or you can return the electronic load to local

control by long -pressing “Lock/Local” key.

Details of local operation are covered in Chapter Local Operation and fundamentals of remote programming

are given in Chapter Remote Operation. Complete SCPI programming details are given in the “Electronic

Load SCPI Programming Guide”.

3.2. Main Function

Main functions (features) of electronic load:

- Constant Current Mode (CCL, CCH)

- Constant Voltage Mode (CVL, CVH)

- Constant Resisitance Mode (VL CRL, VL CRM, VL CRH, VH CRL, VH CRM, VH CRH)

- Constant Power Mode (CPV, CPC)

- Transient Operation (Tran)

- Sequence (List) Operation (List)

- Battery Discharge Operation (Battery)

- Shout Circuit Operation (Short)

3.3. Basic Test Function

3.3.0.

There are four modes of operation: constant current(CC), constant voltage(CV), constant resistance(CR),

constant power(CP), and nine test modes: CCL, CCH, CVL, CVH, CRL, CRM, CRH, CPV, CPC.

The test mode and the associated parameters can be set via front panel or remote command. The

load will remains in that mode until the mode is changed. If the mode is changed when the load’s input is

in ON status, the load will be turned off automatically.

The set value for electronic load becomes effective immediately when the load is turned on. If the

input set value exceeds the allowed range, it will be automatically limited at maximum value or minimum

value.

3.3.1. Constant Current Mode (CC)

3.3.1.0.

Constant current mode has two ranges, the high range(CCH) and the low range(CCL). The high range

provides wider test range. The low range provides better resolution at low current settings. In CC mode,
