  • Page 28 Operation and Demonstration 12/07/18...
  • Page 29 Power Up Steps  When turning on a DET-2 (or any digital theodolite) for a demonstration 5 steps are required: Mechanically rotate the unit Horizontally until the alignment dots are over one another. This orients the tubular vial to the correct relationship to the leveling screws.
  • Page 30 Power Up Steps  When turning on a DET-2 (or any digital theodolite) for a demonstration 5 steps are required: PRESS and HOLD the power button until the display briefly flashes (about 2 seconds). Immediately raise your finger from the button. “TILT” will be indicated at the top of the display.
  • Page 31 Power Up Steps  When turning on a DET-2 (or any digital theodolite) for a demonstration 5 steps are required: LEVEL the DET-2 tubular vial by turning the 2 leveling screws at the back of the unit. The screws should be turned in opposite directions of each other.
  • Page 32 Power Up Steps  When turning on a DET-2 (or any digital theodolite) for a demonstration 5 steps are required: Rotate the DET-2 Horizontally 90°. LEVEL the DET-2 tubular vial by turning the FRONT leveling screw ONLY. Repeat the leveling steps until the DET-2 can be rotated 360°...
  • Page 33 Power Up Steps  When turning on a DET-2 (or any digital theodolite) during a demonstration 5 steps are required: To clear “SET0” from the display rotate the telescope vertically 360°. This lets the vertical encoder “find” its proper zero point.
  • Page 34 Power Up Steps: NOTE  Steps 3 and 4 can be eliminated in a demonstration by entering the menu system and turning TILT OFF. This turns off the TILT sensor and Vertical Compensation.  To turn TILT OFF, see the next section on CHANGING PARAMETER SETTINGS 12/07/18...
  • Page 35 Demonstration  Point out to the Dealer/Customer:  The DET-2 is a 2” instrument, with Vertical Compensation, that is accurate enough for any Construction application. The display can be set to read out in 1” or 5” increments, whichever the customer desires (choice of Accuracy vs Complexity).
  • Page 36 Demonstration  Point out to the Dealer/Customer:  Dual backlit displays and controls for easy operation, especially when turning 90°s  Unique large LCD characters, about 50% larger than other units, PLUS an illuminated Telescope for easy reading indoors, or at dawn and dusk.
