Step 4. Select one of the compensation data definition keys,
OPEN CONDUCT(G)
,
OPEN CAP(C)
,
SHORT RESIST(R)
,
SHORT INDUCT(L)
,
LOAD RESIST(R)
, or
LOAD INDUCT(L)
, to
confirm or set the compensation data definition.
The current value of the compensation data definition is displayed in the setting parameter
area of the LCD's upper-left side.
Step 5. Use the keys or rotary knob of the ENTRY block in one of the following ways to specify
the compensation data definition .
• Enter the desired value with the numerical keys (
[0]
through
[9]
,
[.]
,
[-]
) and then press
one of the unit keys (
[G/n]
,
[M/
m
]
,
[k/
m
]
, or
[
´
1]
).
• Turn the rotary knob ( m
m m
m ) until the desired value is set.
• Press the step keys (
[
­
][
¯
]
) to set the desired value.
NOTE When entering the capacitance value in the compensation data definition, the
[fF]
unit is
automatically added at the end of the value you enter with the unit keys. For example, if
you enter a value with the numeric keys and then press the
[x1]
key, the
[fF]
unit is added to
the entered value.
Step 6. Repeat steps 4 and 5 to set all of the required compensation data definitions.
