CT7 is a handheld instrument. 2. The measurement is performed with instrument standing on the measured mirror. 3. The results are displayed and stored to non volatile memory. 4. All measurements are time‐stamped thanks to the real time clock. 5. An USB connection allows for data retrieval to PC. 6. The instrument has three power modes: ACTIVE, SLEEP and CHARGE. 7. There is no power ON/ power OFF switch; after a period of inactivity, the instrument goes to sleep mode. 8.
Power‐up is invoked by touching the control joystick. 9. Auto OFF feature protects the batteries against accidental discharge. 10. Two NiMh, AA‐size rechargeable cells power the instrument. 11.
