Chapter 1 Start Guide In this chapter, we mainly introduce the panel and display Interface of SPD3303X/3303X-E, as well as the new machine inspection and attentions at first use. Reading this chapter will give you a quick understanding on operation. Brief introduction: • General Inspection • The front panel • The rear panel • User interface • The rear panel • Output check

General Inspection Please check the instrument according to the following steps. 1. Inspect the shipping container. Keep the damaged shipping container or cushioning material until the contents of the shipment have been completely checked and the instrument has passed both electrical and mechanical tests. The consigner or carrier will be responsible for damages to the instrument resulting from shipment. SIGLENT would not provide free maintenance or replacement. 2. Inspect the instrument. If there are instruments found damaged, defective or failure in electrical and mechanical tests, please...

Safety Considerations To ensure that the instrument can work normally, please conduct necessary inspection before using the SPD3303X/3303X-E Input Power Requirement The SPD3303X/3303X-E allows a 50Hz/60Hz frequency, and four levels of AC power: 100V/120V/220V/230V. You can select wanted power voltage with the “DIP Switch” at the rear panel according to the actual demand. Warning To switch to the wanted power voltage, please disconnect the power cord first. Electrical Check Please use the power cord provided as accessory and connects the instrument to AC power. Check the power as the...
