5. Reference Point Adjustment
Note
• Prior to measurement, be sure to follow the procedure below to check and set the reference point.
• Use a calibrated dedicated ring gage for the reference point adjustment of this product.
• Remove any dirt or oil from the ring gage and the measuring surfaces of this product before the reference point
adjustment.
• Use the same position and conditions for both the reference point adjustment and the measurement.
For measurement using the tip of the contact point, use it for the reference point adjustment as well (Figure 1).
• Keep the base of the gage head away from the bottom during reference point adjustment or measurement (Figure 2).
1) For absolute measurement (ABS) mode
Registers (Presets) the diameter of a reference gage such as a ring gage with this product as reference point.
Two preset values (P1, P2) can be registered with this product for setting the reference point. This is useful when using
the same preset value many times, or when switching the value according to the gage head replaced.
Follow the procedure below to register the preset values.
1
Start setting the reference point.
1 Press the SET switch.
>> "P1" or "P2" blinks, and the preset value set at the
last time is shown.
>> Proceed to step
4
-1 if you do not change the
preset value.
2 Press the MODE switch to select "P1" or "P2".
3 Hold the SET switch (for two seconds or longer).
>> The sign blinks, and the preset value becomes
settable.
2
Set the preset value (sign).
1 Press the MODE switch to change the sign.
>> Pressing the MODE switch toggles "+
⇄
-".
2 Press the SET switch.
>> The sign is confirmed, and the next digit blinks.
3
Set the preset value (number).
1 Press the MODE switch to change the number.
>> Pressing the MODE switch cycles "0 → 1 → 2...
→ 9 → 0" in this order.
2 Press the SET switch.
>> The value is confirmed, and the next digit blinks.
>> To skip a digit, press the SET switch.
>> Repeat these steps (1 and 2) to confirm all the
digit numbers.
>> When the lowest digit number is confirmed, "P1"
or "P2" blinks.
4
Register the preset value.
1 Confirm the sign and number you set, and press the SET switch.
>> The preset value is registered, and the display returns to the
absolute measurement (ABS) mode.
5
Set the ring gage (reference gage).
1 Wipe the ring gage and the measuring surfaces of this product
clean.
2 Grasp the lever and slowly insert this product into the ring gage.
3 Slowly release the lever to have the contact points touch the
inner surface of the ring gage.
4 Lightly shake the entire product to ensure that the entire contact
point touches the inner surface (to the largest display value).
6
Call the preset value you set.
1 Press the SET switch twice.
>> The position of the contact points are set as the
reference point with the preset value.
Note
• If you set a wrong sign or number in the step
4
, hold the SET
switch (for two seconds or longer), and retry from step
2
.
• The reference point (sign and number) you set is kept even when
the power is turned off. However, replacing the battery clears the
settings. Reset them.
• To stop or cancel the setting along the way, hold the MODE switch
(for two seconds or longer).
2) For incremental measurement (INC) mode
The incremental measurement (INC) mode is useful when comparing the
diameter of the workpiece with that of the master.
1
Set the ring gage (reference gage).
1 Wipe the ring gage and the measuring surfaces of this product
clean.
2 Grasp the lever and slowly insert this product into the ring gage.
3 Slowly release the lever to have the contact points touch the
inner surface of the ring gage.
4 Lightly shake the entire product to ensure that the entire contact
point touches the inner surface (to the largest display value).
Note
Do not move the inserted product until completion of setting
the reference point.
2
Press the SET switch for two seconds or longer.
>> The display value is cleared (zero-set), and "INC" lights.
6. How to Measure
Insert this product into the workpiece with the same position and procedure as for the reference point adjustment and
read the display value.
When the tolerance judgment function is not set to OFF, the result is shown.
7. Holding of Display Value (No Connection to External Device)
Display value can be held (fixed).
1
Press the DATA/HOLD switch in the measurement mode.
>> "H" lights, and the display value is held.
2
To release the hold, press the DATA/HOLD switch again.
Note
The hold function does not work when the DATA/HOLD switch is
pressed during the tolerance judgment enlarged display.
8. Tolerance Judgment (Upper and Lower Limits Setting)
Set the allowed upper and lower limits against the reference value in order to judge whether a measured value is within
the range (tolerance) and thus acceptable.
For the tolerance judgment function, "OFF", "Normal display of judgment result",
or "Enlarged display of judgment result"
can be selected.
The tolerance value can be set for each absolute measurement (ABS) mode and incremental measurement (INC) mode.
Note
The upper and lower limits can be set for each measurement mode (ABS and INC). Confirm that the desired measure
-
ment mode is selected before starting the setting of the tolerance judgment.
Follow the procedure below to set the tolerance judgment function.
1
Enter the parameter setting mode.
1 Hold the MODE switch (for two seconds or longer)
in the measurement mode for which the tolerance
judgment function is set.
>> The display enters the parameter setting mode.
2
Select the tolerance judgment function.
1 Confirm that the tolerance judgment function (
)
is shown.
2 Press the SET switch.
>> The tolerance judgment function can be set.
3
Set the method of displaying the judgment result.
1 Press the MODE switch to select the method of
displaying the judgment result.
>> Pressing the MODE switch cycles "OFF" (Disable
the tolerance judgment) → "
" (Enable the
tolerance judgment (normal display)) → "
"
(Enable the tolerance judgment (enlarged
display)) in this order.
2 Press the SET switch.
>> The setting is confirmed.
>> When "normal display" or "enlarged display" is
set, "
▶
" blinks, and the upper limit can be set.
>> Setting "OFF" proceeds to the next parameter
"
" (function lock).
4
Set the upper limit.
1 Hold the SET switch (for two seconds or longer).
>> The sign blinks, and the value can be set.
2 Press the MODE switch to set the value.
>> Pressing the MODE switch cycles "+ → -", "0 →
1 → 2... → 9 → 0" in this order.
3 Press the SET switch.
>> The value is confirmed.
>> The next digit blinks, and the value can be set.
>> Repeat these steps to confirm all the digit values.
>> When the lowest digit value is confirmed, "
▶
"
blinks.
4 Press the SET switch.
>> "
◀
" blinks, and the lower limit can be set.
5
Set the lower limit.
1 Set it as with the upper limit.
2 Press the SET switch to finish the setting of the
lower limit.
>> The display shows the next parameter "Fn-Loc".
Note
• When a lower limit larger than the upper limit is set, "Err 90" is displayed, and the values set are cleared. Press the
SET switch to cancel the error display, and start the setting again from the upper limit. (See "10. Errors and Counter-
measures".)
• Different tolerance limit values cannot be set between "normal display" and "enlarged display".
• To stop the setting along the way, hold the MODE switch (for two seconds or longer). Note that any unconfirmed
settings are discarded.
• All settings are kept even when the power is turned off. However, replacing the battery clears the settings. Reset
them.
Note
Do not move the inserted product until completion of setting
the reference point.
