Step 2. Press the
USER CAL
key to display the User Calibration Menu.
Step 3. Press the
DEFINE VALUE
key to display the Calibration Data Definition Menu.
Step 4. Select one of the calibration 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 calibration data definition.
The current value of the calibration data definition is displayed in the parameter setting
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 calibration 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 the capacitance value of the calibration data definition is entered with the numerical
keys and one of the unit keys, the unit [fF] is automatically added to the entered value.
Step 6. Repeat procedures 4 and 5 to set all of the required calibration data definitions.
