General Safety Summary Read the following safety precautions carefully to avoid any personal injuries or damages to the instrument and any products connected to it. To avoid potential hazards, please use the instrument as specified. Use proper power line. It’s only allowed to use the special power line which is approved by local state. Ground the instrument. The instrument is grounded through the protective terra conductor of the power line. The ground conductor must be connected to the earth to avoid electric shock. Make sure the instrument is grounded correctly before connecting its input...

Avoid circuit or wire exposure Don’t touch exposed contacts or components when the power is on. Don’t operate without covers. Don’t operate the instrument with covers or panels removed. Use proper fuse. It’s only allowed to use the specified fuse for the instrument. Use proper overvoltage protection. Make sure there is no overvoltage (like voltage caused by thunder and lightning) reaching to the instrument, otherwise the operator may suffer an electric shock. Antistatic protection. Static electricity will cause damages to the instrument, so test in antistatic areas as far as possible....

Input terminal protection limitation Protection limitation is defined for the input terminal： 1. Main input（HI and LO）terminal HI and LO terminals are used for Voltage, Resistance, Capacitance, Continuity, Frequency, Diode and temperture measurement. Two protection limitations are defined:  HI-LO protection limitation: 1000VDC or 750AVC. It’s the maximum measurable voltage. The limitation can be expressed as 1000Vpk.  LO-ground protection limitation：LO terminal can “float” 500Vpk relative to the ground safely. The maximum protection limitation of HI terminal relative to the ground is...

IEC Measurement Category II Overvoltage Protection SDM3045X Digital Multimeter provides overvoltage protection for line-voltage mains connections meeting both of the following conditions to avoid the danger of electric shock： 1. The HI and LO input terminals are connected to the mains under Measurement Category II conditions as following. 2. The maximum line voltage of the mains is 300VAC. WARNING: IEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit, such as most small appliances, test equipments, and other devices that plug into a...

CAUTION: Caution statements indicate the conditions and behaviors that could result in damage to this product or other properties. CAT I (1000V): IEC Measurement Category I. The highest measurable voltage is 1000Vpk in the HI-LO terminal. CAT II (300V): IEC Measurement Category II. Inputs may be connected to mains (up to 300VAC) under Category II overvoltage conditions. Terms used on the instrument....

Daily Maintenance and Cleaning Maintenance When storing or placing the instrument, please avoid the liquid crystal display from direct sunlight for a long time. NOTE:  To avoid damages to the instrument or test leads, please don’t place them in mist, liquid or solvent. Cleaning Please often clean the instrument and test leads according to the use of them.  Wipe the external ash of the instrument and test leads by a soft rag. Be careful not to scratch the transparent plastic protective screen when cleaning the liquid crystal screen.  Use a soft rag that has been soaked by water to clean...

General Inspection 1. Inspect the shipping container. Please keep the damaged container or cushioning material until the contents of the shipment have been checked completely and the instrument has passed the electrical and mechanical test. Damages of the instrument caused by the shipment will be compensated by the shipper or carrier. SIGLENT will not be responsible for the free repair or replacement. 2. Inspect the instrument. If there exit any mechanical damages or lacking of components, or the instrument fails the electrical and mechanical test, please contact your SIGLENT sales. 3....

Connect Power Cord Before connect the instrument to a power source, please select the AC voltage selector on the rear panel of your multimeter according to the power supply.Then connect the power cord as shown in the following figure. Connect Power Cord Press the Power key on the front panel to start up the multimeter. If unable to start up the multimeter, take the follow steps: 1. Check the power cord connection. 2. After the inspection, if the power key is not lit, please take out the fuse and check, refer to the fuse specification shown in the User Manual to change the fuse if needed. 4....

Power Selection The Multimeter is able to operate on multiple power distribution standards and must be set up according to the supply voltage. If the selected supply voltage doesn’t match the working voltage while using, the setting of the Multimeter’s supply voltage must be changed. The power selector is located under the power fuse on the rear panel. Change the Power Fuse The power fuse is located in the fuse block on the back panel. The Multimeter has installed a power fuse before leaving the factory. It’s a kind of fast-melt, no-burst, F300mA, 5×20mm one. Change the fuse SDM3045X Quick...
