3. SETTING UP

3.1 Packing list

The standard packing of the instrument includes the following elements:

1. Instrument with display unit and measuring insert holder

2. Measuring insert

3. Setting gauge

4. Charging unit

5. User’s manual

6. Calibration certificate

While unpacking, carry the instrument by lifting if by its displacement handle (8) and body. In

NO case should the instrument be carried by the handle for carriage displacement (3). Keep the original packaging for future transportation.

If the instrument has been stored at a temperature below 5°C, wait a few hours before unpacking to prevent the instrument parts from condensation. Condensation can affect sensitive parts of the instrument.

750 50 0045 03 6

Page 9

V3 / V4

3.2 Setting-up

After unpacking, prepare the instrument as follows:

1. Clean the pads positioned underneath the base using a clean cloth, slightly dampened with alcohol.

2. Position the instrument with care on a clean measuring plate.

3. Slide the measuring insert into the holder and lock it, using the knob. Take care to position the eccentric probes correctly.

4. Release the transport safety screw (chromium-plated).

Note: Do not try to remove the screw (screw stop)!

5. If the instrument does not switch on or in case of low battery level, proceed to a full loading of the batteries (plug in the charging unit to the instrument). Empty batteries are fully loaded in about 3 hours.

Only use the charging unit supplied with the instrument to load the batteries.

It is not necessary to wait until the battery pack is fully charged. The instrument becomes operational immediately after having connected the charging unit.

It is not dangerous to leave the charging unit connected. Permanently plugged-in instruments automatically switch to trickle charge mode.

The batteries are of Lithium-ion type. An excessive room temperature can affect the battery capacity and therefore the instrument autonomy. It is not recommended to load the battery in case of room temperature superior to 40C°.

Incorrect loading of the battery can result in a decrease of capacity, overheating, or even an explosion and cause important damages.

The charging units can be loaded and unloaded 300 times before a significant reduction of their capacity. The number of loading cycles and the autonomy can vary according to use and operating conditions.

4. GETTING STARTED

4.1 Setting into operation

1. Switch on the instrument by pressing button On/Off during 2 seconds. All segments of the display will light up. Switch off the instrument by pressing the same button until the instrument turns off.

> 2 s

2. The display will ask for the reference position. Move the measuring carriage slowly across the mark indicating the reference position with the help of the handle for carriage displacement (the acquisition of reference is carried out by displacing the carriage upwards). An acoustic signal will confirm that the reference has been detected and the display starts counting. If the display does not start counting, repeat the sequence.

Note : V5/V6: This procedure is carried out automatically in motorized mode.

3. The instrument is now asking for the probe constant.

This function compensates the dimension and the deflexion of the measuring insert when probing downwards and upwards (reversed surfaces, diameters). The last stored probe constant value will be displayed.

Note 1 : This procedure may be interrupted by pressing on the probe constant key or on the

Validation key

. The latest

probe constant value measured is then recorded.

Note 2 : The start mode can differ, according to the instrument configuration (§

8).

750 50 0045 03 8

Page 11

V3 / V4

4. Use the setting gauge supplied with the instrument to carry out this operation.

Note: A different setting gauge may be used. In this case, its dimension must be configured in the set-up menu (§ 8).

5. Move the measuring insert downwards (use the handwheel for the displacement of the measuring carriage) until it touches the surface and an acoustic signal confirms the measurement (=probing).

6. Without moving any part (instrument and gauge), move the measuring insert towards the top and perform the same sequence on the upper surface of the setting gauge.

7. Repeat the sequences 5 and 6 one more time. This allows establishing the probe constant more precisely.

8. The screen will display the setting gauge value during the latest probing, as well as that of the new probe constant. The instrument is then ready to be used.

The probe constant needs to be checked and stored again after each measuring insert change, after change of its position in the holder, after each adjustment of the measuring force or adjustment of the floating probe suspension.

9. APPLICATION AND ADJUSTMENTS

9.1 Probing

The measurement precision is directly linked to the quality of contact between the probe and the part to be measured (⇒ probing). The instrument offers all tools allowing an optimal probing:

Probing indicator

Situated on the left of the measured value, it views the probing zone (1).

If the probing zone has been passed, the display shows-.- - and an acoustic signal rings out as long as the indicator remains out of the probing zone.

Probing direction indicators Besides the acoustic signal, the measurement is visually confirmed by the indicators of the probing direction (2) and by the probing symbol (3).

Acoustic signal

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

9.2 Air Cushion (V4)

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 some 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.

The air cushion force can be adjusted in the set-up menu (§

8).

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.

9.3 Adjustment of floating probe suspension balancing

In order to guarantee a constant measuring force in both directions (upwards and downwards), it is necessary to adjust the balancing of the floating probe suspension according to the probe in use.

The adjustment button of the floating suspension (1) allows compensating the weight of the probe in use.

A function facilitating the balancing can be found in the setup menu (§ 8).

9.4 Replacement of battery block

When the instrument autonomy is not sufficient anymore, the battery block must be replaced :

1. Get a battery block from your TRIMOS agent (Trimos réf.: 3704 0021).

2. Open the lid at the back of the display.

3. Remove the old battery block and replace it by the new one (pay attention to the connector polarity).

4. Close the lid tightly.

5. Load the new batteries.
