11.Description

22.Effective Displacement of Contact Point
・The range of contact point (S) and the effective measuring range (R) are shown below (Figure 1).
・Consider the center of the effective measuring range (Po) the neutral point and the length from thereplacement rod to Po the nominal value of the bore gauge (L D). (The nominal value in Figure 2 isdetermined by the combination of the replacement rod and replacement washer.)・It is recommended to set the mean value of the whole measurement tolerance range to L D. For
example, if the measurement dimension is 100±0.05, set 100 to LD. If the dimension is100.5 +0.02/-0.08, it is ideal to set 104.97 to LD.

3.Usage
The bore gauge is a comparative measurement instrument. Before using this gauge, adjust thezero point by using a ring gauge, micrometer, gauge block, or other tool, which functions as
reference gauge.
3-1．Attaching the indicator
1) Loosen the dial clamp screw and insert an indicator into the dial holder.
Slowly insert the indicator while monitoring the indicator’s reading.
2) Insert the indicator at least 0.3 mm. Fasten the dial clamp screw to fix the indicator inplace. (Fig.3)

Clamp screw<NOTE>
・Refer to user's manual of indicator clamped (SSI-250).
・Do not remove, insert or rotate the indicator with the dial clamp fastened. This could damage theproduct or indicator.
・If the dial clamp’s indicator insertion hole is deformed by mistake, correct it by inserting an φ8mmstick.

33-2．Dimension settings (modification of measuring range)
Set the measurement dimension by attaching the replacement rod, replacement washer, or subanvil suited for the measurement dimension.
・Setting the dimension by attaching the replacement rod, replacement washer, or sub-anvil.
Select the replacement rod or other part by referring to
the nominal value of the measuring range on the anvil plate
Fig.5
or conversion chart and “6. Effective Displacement ofContact Point”. Because the method for attaching thereplacement rod or other part differs depending on themodel, refer to the figure below (Fig.5). If attaching multiple
replacement washers and/or sub-anvils, use as few
replacement washers and/or sub-anvils as possible.
Tighten the screw part or supporting nut and check forlooseness before securing the interchangeable rod.

3-4．Zero adjustment
The reference gauge is necessary for zero adjustment. This section describes a typical zeroadjustment procedure.
・Zero adjustment using the ring gauge
To periodically measure workpieces that have the same specifications for a long time (such as
when inspecting mass-produced products), it is convenient to have a master ring for zeroadjustment. The procedure for this adjustment is the same as the actual measurement method.
Insert the bore gauge into the master ring, vertically or horizontally swing the bore gauge, and set"zero reset" to the point where the indicator mounted reads the minimum value.
・Zero adjustment using the outside micrometer.
Place the micrometer onto the stand so that the head side (spindle side) faces downward. Fix it in
the vertical position and open the necessary length.
Insert the bore gauge between the two measuring faces of the micrometer and set the zero pointof the indicator to the point where the indicator reads the maximum value. Some skill is required
for this operation because the centripetal force by the guide cannot be used during zero adjustmentusing the micrometer.
・Be sure to use the wrench that comes with the product to remove or attach
the replacement rod or micrometer head (except for models where thereplacement rod is fixed in place using supporting nuts).
・For zero adjustment using the outside micrometer, be sure to keep themicrometer in the vertical position and hold it so the spindle side faces
downward. Perform this work without clamping the micrometer spindle.
・Always perform zero adjustment after setting the measurement
dimension and before starting measurement. Even when performing
measurement processes in series, perform zero adjustment before
each measurement process whenever possible.

53-5．Measurement
Measurement can be started once the indicator is attached, the measurement dimension is set,and zero adjustment is completed. The bore gauge can measure not only the inside diameter of acylinder but also the distance between two parallel planes. Some skill is required because thecentripetal force by the guide cannot be used, as when performing zero adjustment using outside
micrometer or in the case of a model without a guide.
Measurement procedure1) Insert the measurement target into the bore gauge.
2) Short press
button of indicator, then it is "Zero reset".
3) Vertically or horizontally swing the bore gauge.
4) It is displayed the minimum value held.
5) Short press
button of indicator, then the measurement
data can be sent to PC by Bluetooth.
Do not insert the bore gauge from the replacement rod side. Always insert it from the contact
point/guide side and insert the replacement rod side while pushing the guide against themeasurement target.

4. About Extension Sleeve (Optional Accessory)
The measuring depth can be extended using the extension sleeve to measure a deep holethat cannot be measured with the standard bore gauge.
Extension Sleeve
Extension sleeve attachment procedure
1) Fix the outer sleeve to the extension sleeveby using the wrench that comes with theproduct and remove the head by rotating it
counterclockwise.
2）Screw the extension sleeve in the outer sleeve.
3）Screw the head into the extension sleeve.
・The user’s posture might adversely affect the accuracy whenthe extension sleeve is used. It is recommended to keep thesame posture as that when you adjusted the zero point.
・Fasten the head to the extension sleeve slowly and firmly
so that the internal shafts are coupled.
・Tighten the screw part so that it will not loosen. If it is not tightly
fixed, a breakage, inaccuracy, malfunction, or part drop mightoccur causing an injury.
・Do not relay multiple extension sleeves.

5.Maintenance, Checking, Servicing, and Repairing
・Wipe off outside stains with a soft dry cloth or cloth soaked with neutral detergent or alcohol.
Do not use other organic solvents (such as thinner or benzene) for resin parts.
・If the gauge is not to be used for a long time, clean it, apply an anti-corrosive treatment, andthen store it in a place without condensation.
・Before using the gauge after a long time, check the accuracy and operation of the bore gauge
and indicator.
・The performance of this product largely relies on the usage and storage conditions. It isrecommended to stipulate an inspection period in your internal standards or another document
considering the usage frequency, environment, storage method, and other elements, andperiodically inspect the product.
・Teclock does not guarantee the performance, if a third party repairs the product.
