The POCKET-II equipment is powered by direct current (DC) voltage. 1-3 POWER SUPPLY The POCKET-II equipment requires four 1,5V AA batteries in order to operate. An optional external power supply may be used to replace the batteries. This external power supply can be found in any country with the appropriate regulation. The voltage and current required are 9V DC and 500 mA. Do not remove the batteries before connecting to the external power supply (in order to safeguard the configuration data) . external power supply placement

6- MAINTENANCE 6-3 CHECKING PROCEDURE The measurement acquisition may be checked with the test-block : TEST Test-block 1- Dampen the probe extremity with water and place it perpendicular on the Pocket-II test block like indicated below.

Do not put water on the test block 2- Press “MEAS”. The acquisition should be fast : if necessary, change slightly the position of the probe to obtain an acquisition. You ear a repetitive sound while the position of the probe is incorrect. You must be perpendicular like the opposite diagram.

90°

Test-block on the Pocket-II

Note : Make a series of measurments to have a representative Standard Deviation (SD). Rev 11-2003

SERVICE MANUAL

3- Results of the test : if the procedure has been succesfull and the position of the probe is correct, the readings of the series of measurements must be repetitive to ± 20 µm. As some microns represent a very thin thickness, some parameters influencing the test-block itself : - the variation of the thickness with the ambiant temperature. - possible dust. - Incorrect positioning. If you suspect any problem, please call for Service.
