Page 13: Operating Instructions
Operating Instructions General Information The logical front panel layout of S 6020 ensures rapid familiarization with the various functions. However, even experienced operators should not neglect to carefully read the following instructions, to avoid any operational errors and to be fully acquainted with the instrument when later in use. -
Page 14: First Time Operation
First Time Operation Switching : Plug the mains cable into the mains socket at the rear of the instrument. Now plug the other end into a suitable mains outlet. To switch ON, press power ON switch . On application of power, the LCD displays range and functions etc . - Page 15 while the resistance series eq ckt represent resistance of coil. Heavy inductors are preferably measured with the parallel Eq ckt this case being domination compared to the series resistance. The low values inductors are themselves represented by the series, their reactance being low. In order to obtain a more accurate result high inductances are analyzed with the lowest rate, while low inductors are analyzed in contrast with the highest.

Page 16: Understanding Displayed Parameter
Understanding Displayed Parameters Q Inductance and quality factor : The inductor is displayed on the first line of the LCD. Units of the inductance are H, or μH, mH. Q is the ratio the imaginary part of the impedance and has no unit. The Q value is the same for both types of equivalent circuits (series or parallel). -
Page 17: Measurement Of Transformer Parameters
R + X Strength and Reactance : The resistance is displayed on the first line, reactance on the second line. These two values match respectively to the real and imaginary part of the component are expressed in or M . - Page 18 The following parameters are displayed by successive push on the N / Vs / M for the Characterization of processors. The main parameter N is the report of turns ratio between the primary and the secondary winding. The phase shift primary / secondary and the frequency of testing are listed on the second Line.

Page 19: Component Sorting & Binning Function
Component Sorting & Binning Function The instrument allows comparison of components compared to a preset value. The instrument will calculate the deference between the value preprogrammed, which can be displayed in the form of an absolute deviation or percentage. To access the sorting function press Menu. Press the button F2 for the right arrow (N / Vs / M) until sorting option appears. -
Page 20: Display Types
Display Types (DISP Push Button) Users can select three possible display types with successive press of DISP button. The measured value The difference in value in relation to the current value. The symbol will show next to the Measured parameter indicates that the function is active. If the sorting mode is active message PASS FAIL is displayed on the second line depending on the value of the component, the nominal value and the percentage are defined by the user. - Page 21 3- For setting nominal value for sorting , press F2 once again after step 1 discussed above. This will display Value option, press F3 to edit . Press F1( NEXT) for moving cursor,F2 (CHANGE) for changing values at cursor position from 0 to 9 , even units can be changed to m, k, M etc.

Page 22: Zero Compensation
Zero Compensation or OPEN / SHORT calibration Zero compensation or open-short calibration function of the instrument can compensate for the parts of the measuring cable in order to compensate for parasitic elements. The model used is the one represented in the figure below. The instrument determines the value of these elements Rss and Lss at a preliminary measure. -
Page 23: Frequency Of Test
Calibration short : maximum series resistance of the cables must be less than 8 while the total impedance should be less than 8 Calibration open : parallel impedance of the cable must be more than 1M . The instrument displays the zero readings after adjustment or near zero value , except for small negligible value ( to be ignored , part of value too small in comparison to the range) if the calibration went well, “Failed”... -
Page 24: Impedance Range
Impedance Range The Instrument has 6 impedance ranges (R1-R6). The range of impedance can be selected manually or can be set to automatic, which is the normal or default mode. Range in use is indicated on left in 2 line with word A or H (Flashing) meaning auto or manual. -

Page 29: Remote Programming
A present value of a particular parameter may be determined by querying the SM6020 for its value. A query is formed by appending a question mark “?” to the command mnemonic and omitting the desired parameter from the command. - Page 30 FREQ (?) {i} The FREQ command sets the drive frequency according to the table below. The FREQ? query returns the drive frequency. Frequency 100 Hz 120 Hz 250 Hz 500 Hz 1 kHz 2.5 kHz 5 kHz 7.8125 kHz 12.5 kHz 15.625 kHz 25 kHz User frequency...
- Page 31 RNGH (?) {i} The RNGH command disables (i=0) and enables (i=1) range hold. When range hold is disabled the SM6020 will autorange. The RNGH? Query returns the range hold status. VOLT (?) {i} The VOLT command sets the drive voltage to 50 mV (i=0) and 500mV (i=1).
- Page 32 The PREL command sets the relative parameter value for deviation and percent deviation measurements to x. This command will return an error if the SM6020 is set to AUTO parameter mode. The units of x are Ohms in R+Q mode, Henrys in L+Q mode, and Farads in C+D mode.
