Chapter 6 Troubleshooting & Maintenance RIGOL DM3058 Principle Summary The circuit of DM3058 can be divided into floating circuit, grounding circuits and power input. 1. The floating circuit includes current fuse, signal input end of front panel (banana socket) and measurement analog front-end which contains all the circuits of measurement function such as input protection, function switch, signal transform conditioning, A/D conversion and control interface.
Chapter 6 Troubleshooting & Maintenance RIGOL 2. Ground circuit contains most circuit such as keyboard, LCD, USB Host, BNC board, LAN/GPIB board and the host CPU. 3. The AC supply inpour the meter via power socket and connect to transformer through filter board, from which, it will be stepped down or divided into multi low voltage and then respectively supply for floating circuit and grounding circuits.
Chapter 6 Troubleshooting & Maintenance RIGOL Troubleshooting Common Troubleshooting 1. After press the power switch, the multimeter is blank screen with nothing display: (1) Check if the power is correctly connected. (2) Check if the power switch on Rear panel has been turned on. (3) Check if the power light on Front panel is bright. (4) Check if the safety fuse is blown; replace a new one if necessary. (5) Check if the power selector is in correct position.
Chapter 6 Troubleshooting & Maintenance ! RIGOL CAUTION Make sure the power is cut off before replacing fuse, and the specifications of fuse should be in accordance with the requirements in this manual. 2. When the reading of small capacitance is not stable or the offset is a little bigger: (1) Shielded cable must be used to connect the capacitance while measuring small capacitance so as to reduce the influence to result from exterior interference.
Chapter 6 Troubleshooting & Maintenance RIGOL 8. When fail to connect with the meter via LAN interface: (1) Check whether the type of netting twine is correct and still connected. (2) Check whether the indicator light of network connections of the meter is in normal state; if not, that denotes there may be something wrong about LAN. (3) Check whether the address of both DHCP and IP and the settings of DNS are in accordance with the configuration of all LANs.
