10 Application and adjustments

10.1 Application of the manual and the motorized handwheel

3

Manual handwheel

The manual handwheel embodies 3 functions:

- Displacement of the measuring carriage (1).

- Locking device (2) for the fine adjustment movement and to keep a connected probe in position.

- Fine adjustment screw (3) for a precise displacement of the measuring carriage.

2

Motorized handwheel

The displacement of the measuring carriage is done by a rotating movement of the handwheel (max.

±60°). The measuring carriage speed is proportional to the rotation. 4 zones are available:

: Measuring zone (slow movement with a slight stop)

and : Normal displacement speed

and : Progressive fast displacement speed

10.3 Probing movement

The accuracy and repeatability of measurements depends on the contact quality of the measuring insert on the part to be measured (

⇒probing on surface). The instrument embodies all necessary elements to perform optimum measurement :

Probing indicator:

Located at the left side of the displayed measuring value, the probing indicator controls the measuring insert position with set measuring force. During a probing movement, the moving line must stay between the 2 marks of the measuring zone

(green background). If the measuring zone will be exceeded, the indicator background becomes red.

Indicator

Measuring zone

Acoustic signal

An acoustic signal confirms a correct measurement probing movement (measuring force set) and that the value has been stored in the buffer.

Acoustic signal

Measurement downwards

Measuring direction arrow

In addition to the acoustic signal, the measurement is confirmed visually by a direction arrow (green LED)

Measurement upwards

Shock (motorized version)

If the measuring insert has been set with too high speed on a profile or if the measuring zone has been passed (red indication), a shock will be mentioned (text "Collision"). The probe constant and the reference must be rechecked and the measurement repeated.

10.4 Battery pack (operational lifetime, power capacity…)

Battery type: NiMH. They can be charged and discharged at least 500 times before their power capacity will decrease. To optimise the operational lifetime of the battery pack and to allow them to obtain a maximum power capacity, perform at least 5 complete charging cycles when using the instrument initially. Generally, it is recommended to discharge the battery completely before charging again. Do not keep the instrument for a too long period with an empty battery pack.

10.5 Test of luminous LED's

When switching ON the instrument, the LED's lights up for a short period of time. This is a functional test.

10.6 Measurement with / without air cushion displacement

The use of the air cushion facilitates the displacement of the instrument on the granite plate. The activation of the air cushion lifts the instrument at about 2

µm. The air cushion is not only used for the displacement of the instrument in general but also when performing measurements (e.g. diameters). The main application is found particularly in industrial fields with large heavy parts. Small parts can be moved without activating the air cushion. This allows to significantly increase the autonomy of the instrument.

When using the air cushion displacement for measurement procedures, all functions e.g. zero or preset setting of the display should be done with air cushion to take into consideration the lifting amount of the instrument.

10.7 Reset mode

If the instrument does not work properly, a reset is possible using the Reset key located at the rear of the display unit.

This key can be reached through an opening by a pin of dia.

1 mm / length of 20 mm.

10.8 Adjustment of the measuring force

1. The instrument is supplied with a standard measuring setting of 1 N. The measuring force adjustment screw is located inside the column protection profile on the measuring carriage. The screw can be reached through the opening in the protection profile. Use a 2 mm allan key for adjustment. By turning the screw clockwise, the measuring force will be increased.

2. Check the measuring force using a dynamometer (force gage). Bring the dynamometer lever in contact with the measuring insert. Move either the lever or the insert until the sound of the acoustic signal and read the measuring force on the dynamometer. Repeat the same procedure for the opposite movement. Compare the results and readjust if necessary. The measuring force must be equal in both directions.

10.9 Adjustment of the floating probe suspension

To guarantee a constant measuring force in both directions (measurement upwards and downwards), adjust the floating probe suspension according to the measuring anvil/ holder used.

1. The screw for the adjustment of the floating probe suspension is located inside the column protection profile on the measuring carriage. The screw can be reached through the opening in the protection profile. Use a 2 mm allan key for adjustment. By turning the screw clockwise, the probing will be relieved. This means, that the measuring force for probing in downwards direction using the standard insert will be lower.

2. To test the floating probe suspension, use a dynamometer. Bring the dynamometer lever in contact with the measuring insert. Move either the lever or the insert until the sound of the acoustic signal and read the measuring force on the dynamometer. Repeat the same procedure for the opposite movement. Compare the two results and re-adjust if necessary. Both directions must be balanced (equal values). and

10.10 Position of the measuring insert in the holder

Be careful about the position of the measuring insert in the holder. The orientation of the insert is extremely important for a perfect contact of the ball insert on the measuring surface for zero setting.

10.11 Replacing the battery pack

As soon as the autonomy of the instrument becomes unacceptable, change the battery pack:

Wrong

1. Purchase a new battery pack at your local TRIMOS agent (supplied with the upper plastic protection cover).

2. Switch the instrument off, disconnect the AC adaptor and remove the upper plastic protection cover.

3. Disconnect the used battery pack and replace it by the new one. To keep the time and date in memory, the instrument should not be disconnected longer than 2 minutes.

4. Put the plastic protection cover back into position. Be careful about the wires, do not squeeze them.

Use only battery packs, corresponding to the instrument type, supplied by TRIMOS.

Dispose of the used battery pack. Care about the environmental standard regulations.

10.12 Temperature variations

Temperature variations can significantly influence the measuring results. To reduce this influence, it is recommended to check and store the probe constant regularly.

11 Maintenance

11.1 Cleaning

The plastic parts, the display unit as well as the painted parts of the instrument should be cleaned using a slightly wet (watered) fabric. Clean the air cushion pads using a clean fabric, slightly soaked with alcohol.
