JK2817N adopts the following two short-circuit correction data.
No matter how many frequencies you currently set, JK2817N performs a short circuit correction
test on 34 fixed frequencies in the range of 50Hz to 100kHz.Moving the cursor to the short-circuit
region, the soft key short-circuit full-frequency zero-clearing is used to perform full-frequency
short-circuit zero-clearing. 34 fixed frequency points are the same as the open-circuit correction.
Note: JK2831 is a short-circuit correction test for 37 fixed frequency points in the range of
50Hz-200kHz. JK2832 is a short-circuit correction test for 41 fixed frequency points in the range
of 20Hz-200kHz.In addition to 41 frequency points, The short-circuit correction data of other
frequency points will be calculated by insertion calculation method,The short-circuit correction
data of different test frequencies under different ranges are calculated.
JK2817N can set two short-circuit correction frequency points in the frequency domain of <User
Correction >page: frequency 1, frequency 2. Move the cursor to frequency 1, frequency 2. Use
soft-key short-circuit single-frequency zero-clearing to correct the two set frequencies
respectively.
Short circuit correction function operation steps
Short-circuit correction includes full-frequency short-circuit correction with insertion calculation
method and single-frequency short-circuit correction with two set frequency points.Perform the
following steps are taken to carry out short circuit correction for all frequencies by inserting
calculation method.For single frequency short circuit correction, please refer to "load correction"
operation instructions.
1)Move the cursor to the short setup domain, and the soft key area of the screen displays the
following soft keys
●ON
●OFF
●Short circuit full frequency clear
●DCR Short circuit
2)Connect test fixture to instrument test end. Short circuit test piece is short circuited.
3)Clear the whole frequency by pressing the soft key.JK2817N will measure short-circuit parasitic
resistance (resistance and reactance) of 34 frequency points.Short-circuit full-frequency correction
takes about 50 seconds. In short-circuit full-frequency correction process, the screen displays the
soft key below.
