Calibration Explanation
The DM3058/DM3058E calibration consists of user calibration and factory calibration.
The calibration parameters acquired from the calibration performed by RIGOL factory
or the RIGOL authorized third-party organizations are stored as the factory
calibration parameters. The calibration parameters acquired by performing the
calibration operations mentioned below are the user calibration parameters which will
not overwrite the factory calibration parameters. You can select the desired type of
calibration parameters or restore the user calibration parameters to the default values
via the menus. After the user calibration parameters are saved, they will not be lost at
power-off.
Press ; press T/C  PSW and input the correct password; set SecrOff. Then,
press Cal to enter the calibration menu and execute the calibration to acquire the user
calibration parameters. You can press Default under the calibration menu to restore
the user calibration parameters to the default values. Press On/Off to select “On” and
the multimeter will correct the measurement results according to user calibration
parameters; press On/Off to select “Off” and the multimeter will use the factory
calibration parameters.
DC Voltage, DC Current and Resistance
Calibrations
The calibrations of the DC voltage, DC current and resistance measurement functions
consist of the zero point calibration and gain calibration. You should first perform the
zero point calibration and then perform the gain calibration.
The calibration procedures of the DC voltage, DC current and resistance measurement
functions are similar. The introductions below illustrate the calibration procedures by
taking the 4-wire 20 kΩ scale as an example.
1. Read the "Calibration Devices" and "Test Conditions".
2. Press
to select the 4-wire resistance measurement function. Set the range to
20 kΩ and the reading rate to "Slow".
3. Press ; press T/C  PSW and input the correct calibration password; set
SecrOff and press Cal  Enter.
4. As shown in Figure 2-1, short-circuit the Input HI-LO terminal and Sense HI-LO
terminal (namely the zero point calibration input) using a 4-terminal
