Fig. 6.5 Example of shielding box connection
[Warning]
Maximum 1000V of measuring voltage is output between the “GROUND””
terminal and “GUARD” terminal or the “OUTPUT” terminal depending on the
connecting method of the short bar.
Be sure to connect the outer casing of the shielding box to the “GROUND”
terminal.
Use the interlock function to prevent an electric accident.
Exercise reasonable care with an electric shock.
[Note]
As an option, a shielding box model SME-8350 is available.
Set the measuring mode in accordance with the measuring object as explained in 6.2
“Measuring Parts, Circuits and Other Items” and 6.3 “Measuring Planar Sample” when a
shielding box is used.
(2) Interlock function setting
Output of measuring voltage is sometimes not safe such as when the lid of a
shielding box is opened. The INTERLOCK function is useful in these cases.
As in the example of use of a shielding box illustrated in Fig. 6.5, connect the
“open” signal of the shielding box lid to the [INTERLOCK] connector in the rear
of the meter through the interlock connection cable. Then set as follows.
Press the [F1] CONF (CONFIGURATION) key in the Operating Environment
Setting screen. (See Fig. 5.11)
The screen will change to the External Interface Condition Setting screen. (Fig.
6.8)
The External Interface Condition Setting screen is split into two pages.
