  • To turn the instrument on press either the MODE or PROGR keys.
  • Using the MODE and PROGR keys select the appropriate measurement ‘Program’. The program stored in the particular location is listed in the display. The measurements the program actually makes are listed in the table below. You need to check these and select the particular program you require. A more complete explanation of each program is listed in the manual. (section 6.3.1)
  • Point the instrument appropriately and press the MEAS button the appropriate number of times for the particular measurement.
  • The result will be displayed in the eye piece.


  • There are 18 different measurement types available (Section 6.3.1 of the manual)

Description
ModeA Progr1
01 direct D Direct Sloping Distance to a single point
ModeA Progr2
02 reduc D Reduced Horizontal Distance to a single point

03 track D Continuous distance tracking to a single point
ModeA Progr3
04 offset D Difference in horizontal distance between two points, returns horizontal distance and slope angle between the two points.
ModeA Progr4
05 local H Position Height; returns the height of a point and the horizontal distance to the point.
ModeA Progr5
06 plumb H The Perpendicular height between two points
ModeB Progr1
07 height H Height difference between two offset points
ModeB Progr2
08 plumb 3H Height difference between three points on a perpendicular.
ModeB Progr3
09 plumb TH The height difference between four perpendicular points. This returns the height difference between the first three points then the additional height difference to the fourth point.
ModeB Progr4
10 track H Continuous height tracing to a single point.

11 inclin A Continuous angle of inclination
ModeB Progr5
12 Slope A Slope offset angle between two points returns the angle and the horizontal distance

13 azimut Continuous azimuth angle
ModeC Progr1
14 crss dD The direct distance between two points. It returns the direct distance (the hypotenuse) and the height difference between the two points.
ModeC Progr2
15 crss rD The horizontal distance between two points. Returns the horizontals difference and the height difference
ModeC Progr3
16 velocity A single measurement of velocity
ModeC Progr4
17 velotrck Continuous velocity measurements
ModeC Progr5
18 D-scan Continuous distance measurement
  • If the program you need is NOT in a memory location.
    • Ensure the instrument is OFF
    • Hold the MEMORY key
    • Press the MODE key
    • Press the MEMORY key until the display shows the current ‘MODE and PROGR’ together with the program installed in that location i.e. A1–01
    • Press the MODE and PROGR keys to select the appropriate memory location you want to use
    • Press the MEMORY + and MEMORY – to select the program number you want to access from that location. i.e. A1 13 will give you the ‘azimut’ program in the A1 location. The default for A1 is ‘direct D’ measurement program 01.
    • Press Off then Mode again to restart the instrument
