3.1 < element measurement display> page

When the instrument is in the bridge function, press the [DISP] menu button and the < Element
Measurement Display > page will be displayed on the screen.

Figure:

On this page, the test results will be displayed in large characters. The following measurement
control parameters can be set on this page.
● Test function (function)
● Test frequency (frequency)
● Test level (level)
● Test range (range)
● Test speed (speed)
This display page has 5 domains: function, frequency, level, range, speed . Each control function
domain will be explained in detail in the following paragraphs.
The test results / condition display area on this display page shows the following test condition
information. These conditions can be set on the < measurement Settings > page or < user
correction > page.

●Signal source voltage / current monitoring(Vm,Im)
●Open circuit, short circuit, load correction ON/OFF setting status (correction)

3.1.1 Test function

JK2817N can simultaneously measure two parameters of impedance element in one measurement
cycle: one main parameter and one secondary parameter. The measurable parameters are as
follows:
Main parameter
● |Z|

(impedance mode)

● |Y|
