Chapter 1 Setup This chapter describes the procedures from unpacking to installation to operation checking. Upon receiving the product, confirm that the necessary accessories are included and have not been damaged in transit. Should any damage or shortage be found, please contact your Sourcetronic distributor/agent. Items ST90003R withstanding-voltage test leadwires ST90003B withstanding-voltage ground leadwires ST90004 withstanding-voltage test stick Test Report Optional accessories ordered by customer Be sure to observe the following precautions when installing the tester.  Do not use...

Operating humidity range: 20% to 80% RH (no dew condensation permitted) Storage humidity range: 90% RH or less (no dew condensation permitted) Condensation may occur even within the operating humidity range. In that case, do not start using the tester until the location is completely dry.  Do not place the tester in a corrosive atmosphere. Do not install the tester in a corrosive atmosphere or one containing sulfuric acid mist or the like. This may cause corrosion of various conductors and imperfect contact with connectors, leading to malfunction and failure, or in the worst case, a fire....

When moving the tester to the installation site or otherwise transporting it, take the following precautions:  Before moving the tester, turn off the power switch. Transporting the tester with its POWER switch on can lead to electric shock and damage.  When moving the tester, Disconnect all wires from it. Moving the tester without disconnecting the cables may result in breakage of the wire or injury due to the tester tipping over. Checking power source and fuse Toggle power line voltage ！ WARNING: This instrument is designed to operate from the overvoltage category II. Do not operate it...

2. On the rear panel, remove the fuse holder, by pushing it inward and unscrewing it counterclockwise using a screwdriver. 3. In accordance with the fuse rating specified below, check the fuse type and replace the fuse. 4. Following the above steps in the reverse order, reinstall the fuse holder. Voltage range Fuse type Connecting the AC Power Cord The power cord that is provided varies depending on the destination for the product at the factory-shipment. Do not use the AC power cord provided with the product as an AC power cord for other instruments. Connection procedure: 1. Confirm that...

Choose either of the following two available methods of doing so: 1. Connect the AC power cord to a three-contact grounded electrical outlet. 2. Connect the protective conductor terminal on the rear panel to the earth ground. Have specialized engineers select, manufacture, and install cables.To ensure secure connection, use proper tools. Checking Operations Earth Ground Ground ground ！ WARNING Use only the interlock jumper to quickly cancel the protection status. When using this tester, use the interlock function as much as possible to ensure a safe operating environment. To use jigs in...

Checking procedure: 1. Confirm that the supply voltage is the same as that indicated on the rear panel. 2. Confirm that the power socket or the shell of the instrument has reliable grounding. 3. Confirm that the AC power cord is properly connected to the AC LINE connector on the rear panel. 4. Plug in the AC power cord. 5. Turn on the POWER switch. Confirm that all LEDs on the front panel are lit and the opening screen is displayed. 6. Following the opening screen, display the ACW screen and confirm that the tester is kept in the READY status 7. Turn off the POWER switch. Other...

Chapter 2 Precautions on Handling This chapter describes the precautions to be followed in the handling of this tester. When using the tester, take utmost care to ensure safety. ！ WARNING The tester derivers a 5 kV test voltage which can cause human injury or death. When operating the tester, be extremely careful and observe the cautions, warnings, and other instructions given in this chapter. Prohibited Operations Do not turn on/off the power repeatedly After turning OFF the power switch, be sure to allow several seconds or more before turning it ON again. Do not repeat turning ON/OFF the...

Action When in Emergency In case of an emergency (such as electric shock hazard or burning of DUT), take the following actions. You may do either (1) or (2) first. But be sure to do both. 1. Turn OFF the power switch of the tester. 2. Disconnect the AC power cord of the tester from the AC line receptacle. Wearing Insulation Gloves When handling the tester, be sure to wear electrical insulation gloves in order to protect yourself against high voltages.  Precautions for Pausing Tests When changing test conditions, press the STOP switch once to take precautions. If you are not going to resume...

Beware of Residual High Voltages ！ WARNING In DC withstanding voltage testing and insulation resistance testing, the test lead wire, test probe, and DUT are charged to a high voltage. The tester is equipped with a discharge circuit, but some time is nonetheless required to discharge them after the output is cut off. There is a danger of electric shock during discharge. To avoid electric shock, take the utmost care to ensure that the DUT, test lead wire, probe, and highly charged parts around the output terminal are not touched. If it is necessary to touch them, be sure to confirm both (1)...

Also when the tester is in other malfunctioning states than the above, there is a possibility that the output voltage is delivered irrespective of your proper operating procedure. Never use the tester when it has failed. ！ WARNING Keep the tester away from other people until you call our service engineer for help. Immediately call your Sourcetronic agent. It is hazardous for an unqualified person to attempt to troubleshoot any tester problem. Ensuring Long-Term Use without Failures The withstanding voltage-generating block of the tester is designed to release half the rated amount of heat,...
