The default address of GPIB is 1 which is stored in the non-volatile memory and is not influenced by restoration of factory settings. Set the parameters of the LAN interface Before using the LAN interface, connect the load to a computer or the local area network (LAN) where the computer is vissble and ensure sufficient connectivity.
Chapter 3 System Utility Function SIGLENT In this interface, you can view the network connection status and configure the network parameters such as IP address, subnet mask, default gateway and DHCP status. The setting is store in the non-volatile memory and do not influenced by restore factory setting.
SIGLENT Chapter 3 System Utility Function Figure 3-9 Sound tab In the “Sound” menu, you can enable or disable the key sound and tips sound. The load buzzer will sound when you press the key on the front panel or rotate the knob after the key sound is enabled. It will not sound if the key sound is disabled. If the Tips sound is set to ON, the load buzzer will sound when pop-up tips or warning messages. Turn off the Tips sound, and the load buzzer will not sound except during any load protection tips. 3.

Upgrade The SDL1 can be upgraded with new firmware using an external FAT32 formatted USB memory device. To update the firmware, press Shift and CP key to enter system utility function interface. Then switch to page 2 and press the “Upgrade” key on the front panel.
SIGLENT Chapter 3 System Utility Function switch on the front panel is normal or not. Buzzer: Test whether the buzzer can sound or not. Chip Test: Including the self-test result of the load, EEPROM and ADC.
Chapter 3 System Utility Function SIGLENT Config Turn ON/OFF the Sense Function When the DUT outputs large currents, the Sense terminal can be used to accurately test the voltage across the output terminals to compensate for the voltage drop on the load. Set Vrmt to ON to enable the remote sense test function. Turn ON/OFF SOF Function SOF stands for Stop On Fail. When enabled, the auto test function will stop running immediately when any step fails during an auto test.
SIGLENT Chapter 3 System Utility Function Figure 3-11 V - I characteristic curve of Von Latch Set Trigger Trigger operation is mainly applied to the Dynamic, List and Program test functions. The load supports three modes: Manual, Ext and Bus. Manual When the trigger source is set to Manual mode, press the trig tab in dynamic, , List, or Program mode will generate a trigger signal.

Set EXTC (External Interface) The “EXTC” tab includes: (Int, ExtI, ExtV), ExtSwitch, I_M_ON, V_M_ON four tabs. It mainly supply the way user control the external terminals on the rear panel, current and voltage monitor, external control ON/OFF. Int The load will return the mode before enter “EXTC” tab after select the “Int” tab.

SIGLENT Troubleshooting Here are some common failures and their solutions. If the problem persists after following the listed steps, please contact SIGLENT. 1. The instrument cannot start up. (1) Check whether the power is correctly connected. (2) Check whether the power switch at the front panel is really on. (3) Remove the power cord and check whether the voltage selector is at the proper scale, whether the specification of the fuse is correct and whether the fuse is intact.
