5730A Sales and Demo Guide
4) There are 18 discrete resistance values available in the 5730A, from 1 Ω to 100 MΩ in
decade values of 1 and 1.9. The 1.9X values allow you to calibrate most DMMs at near full
scale.
5) To see all available resistance values, press the
list of all selectable values appears. All you have to do is touch the desired value with your
finger!
6) Select "10 k Ω" from the table and hit
7) Now when you adjust the knob, something different happens. Since the resistance values in
the 5730A are discrete, the resistance value cannot be changed in the 5730A. Instead, use
the knob and
screen to match the display of the 8846A. Once matched, the corresponding Error value is
shown in the lower right.
8) Press the
also work for other output functions at any value within the range of the calibrator. This
saves keystrokes when testing DMM ranges at full scale.
DC Current
1) Set the 8846A to measure DC current by pressing the [DC I] key. We will use the Auxiliary
current terminals for this exercise, so move the red (High) cable connected to the 8846A to
the "400 mA" input and move the red (High) cable connected to the 5730A to the "AUX
Current Output" terminal.
2) Enter 100 mA on the 5730A and press
bottom of the touchscreen display so it lights up and displays "Current Output AUX." The
auxiliary current output terminal on the 5730A should now be lit up to verify that you have
made the correct connection. Hit
3) Hit to internally disconnect the 5730A output terminals. The Auxiliary current
terminals allow you to set up a procedure for meters with separate current input terminals
without moving the cables mid-procedure. This is particularly useful when performing
automated procedures in closed-loop operation.
AC Current
1) Press the [AC I] key on the 8846A to select AC current.
2) All of the operation of AC Current functions are very similar to AC voltage functions and
therefore do require a separate demonstration. Feel free to experiment with different AC
current values (9 μA to 2.2 A) between the 2 instruments.
