RIGOL Chapter 4 Calibration The chapter mainly covers the following topics: Calibration Security Code Calibration Notice DC Voltage, DC Current, Resistance Calibration AC Voltage and AC Current Calibration Frequency Calibration Capacitance Calibration Service Guide for DM3000 Series 4-1
RIGOL Calibration Security Code Setting calibration security code can ensure that the multimeter could be calibrated only by authorized person. Before calibrating, firstly you must enter calibration security code. The security code of Multimeter could be made of 10 characters at most which is from number “0~9” and letter “A~Z”. Users can set the self-defined password. The factory default of security code is “DMCAL”, and when power is off or reset, security code will not be changed or lost.
RIGOL Calibration Notice Calibration Interval The multimeter should be calibrated on a regular interval determined by the measurement accuracy requirement of your application. Generally, a 90 days interval is recommended, also a 1-year interval could be used for calibrating depending on your actual requirement. RIGOL does not recommend extending calibration intervals beyond 1 year for any application.
RIGOL DC Voltage, DC Current, Resistance Calibration The calibration procedures of DC voltage, DC current and resistance are similar, so next will take the calibration of 4-wire resistance in the range of 20kΩ as an example to show you procedures. 1. Press to select resistance measurement function, then press Rng+ or Rng- to set the range as 20kΩ and the reading resolution as 6½ ; 2.

RIGOL Chapter 6 Troubleshooting & Maintenance The chapter mainly covers the following topics: DM3000 Principle Introduction Troubleshooting Common Troubleshooting Components Inspection Replaceable Part List Maintenance and Cleaning Even though great care was taken in the design of DM3000 series, problems may occur. So, please read this chapter carefully to get more information about troubleshooting and maintenance.
RIGOL DM3000 Principle Introduction The circuit of DM3000 series can be divided into floating circuit, grounding circuits and power input. 1. The floating circuit includes current fuse, front panel signal input end (banana socket) and measurement analog front-end which contains circuits such as the input protection of all the measurement function, function switch, signal transform conditioning, A/D conversion and control interface.
RIGOL 2. Ground circuit contains keyboard, LCD, USB Host, BNC board, LAN/GPIB board and the host CPU of motherboard. 3. The AC power inpour into the multimeter via power socket and connect with transformer through filter board that divides it into multi low voltage and floating into circuit and ground circuit respectively. The power supply of ground circuit is 9V AC voltage and the floating circuit is a group of 8.5V AC voltage and two groups of 17V AC voltage.
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 main power switch on the Rear panel has been turn 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.
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 display is incorrect: (1) Check whether the range is consistent with test items. (2) Check whether the recommended calibration date is exceed. If the testing value exceeds the range in corresponding accuracy index, please contact authorized calibration center of RIGOL to calibrate.
RIGOL local RIGOL Service center.. 7. For the other malfunctions, please contact with RIGOL maintain ace centre or refer to “service and support. ! 6-6 WARNING: Only authorized personnel by RIGOL could disassemble the instrument, or else no warranty would be available.
RIGOL Components Inspection From this part, you can get more information about malfunction in order to process hard troubleshooting by yourself. 1. Fuse DM3000 have many fuse designs, the one can be changed by customer themselves is power instrument pipe and current fuse, the parameters are as follows: Power fuse: 250V, 300mA, quick-break Current fuse: 10A, quick-break Inspection method： Test the continuity by DM. If no connection beep, the fuse is supposed brown. 2.
RIGOL Compare the measured voltages of each winding with table2.1, we can see that: Table 6-1 Check Table of Voltages among Windings of Transformer windings Original White-Yellow side White-Red Black-Black Vice side White-Yellow Yellow-Brown Blue-Blue Max(Vrms) 132 265 10.8 21 21 10.3 Min(Vrms) 90 180 7.3 14 14 6.9 Typical（Vrms） 110 220 9 17 17 8.5 If all the winding voltages among original side are 0, there might be something wrong with filter board or power source socket.
RIGOL Inspection method: Press the first menu operation key in the left side, at the same time turn on the multimeter, keep pressing for about 5 seconds until you hear beep. After that, multimeter starts testing display. In this state, the basic measure keys, parameter keys and trigger control keys would twinkle and the screen displays keyboard testing menu.
