Fig. 6.1 illustrates connection of a short bar when the “OUTPUT” terminal is grounded
and an equivalent circuit.

(2) Grounding “GUARD” terminal
The “OUTPUT” terminal or “GUARD” terminal can be connected to the
“GROUND” terminal if the sample is not grounded. However, when
measurement is made using a holder or a measuring jig of a part or material and
by providing a guard, the same potential is obtained between the guard circuit
and ground if the “GUARD” terminal is connected to the “GROUND” terminal.
[Warning]
Connecting the “GUARD” terminal and “GROUND,” voltage of maximum
1000V is impressed between the “OUTPUT” terminal and ground
(“GROUND” terminal is grounded) depending on the measuring voltage
setting.
Exercise reasonable care with an electric shock.
