3 Preparation before Measurement
3.1 Preparation of Battery
Checking electric
quantity Refer to "4.1 Start Up" on how to check the power status of the battery.
Before removal of any battery, the instrument must be switched off to avoid malfunction.
Removal of AA-
battery case 1. Turn theknob of the batterycase and let
the mark point to UNLOCK, take the
battery case off.
2. Open the case cover, insert four AA
batteriesintothebatterycase according
to +and -.

Preparation before Measurement T.O.2 | 15
• The four batteries in the battery case should be of the same type.
• Do not use batteries which have different remaining capacities.
• When batteries are wet, dry them immediately, and put them out of the instrument
case, air-dry thoroughly.
Recharging the Ni-
MH battery pack 1. Connect the charger to a power source as indicated on the label of the charger. The green light on the charger is lit.
2. Insert the plug of the charger to the charging port of the Ni-MH battery pack. The
green light of the charger turns red, the charging process is started, after 3 to 4 hours
when the red light turns green, it indicates that the charging process is finished.
3. Insert the raisedpartat thebottom of the
battery case into the slot of the right
battery cover, and put the battery case
in place. Then turn the knob and let the
mark point to LOCK.

T.O.2 | 16Preparation before Measurement
3.2 Erection of the Instrument
Erection of the
instrument 1. Stretch the tripod to a proper hight.
2. Ensure that the measure point is exactly under the central hole of the tripod head.
3. Level up the tripod (this is very important when centering with plumb bob).
4. Ensure that all locking handles are securely tightened.
5. Secure the instrument to the tripod.
3.3 Leveling up of the Instrument
Leveling up of the
instrument
3. Turn the collimation 90° adjust the leveling screw A and make the bubble sit in the
center.
4. Repeat 2. to 3., until the bubble is in the center for both directions.
1. Centering the circle vial using leveling
screws A, B and C.
2. Turn the collimation unit so that the axis
of the tubular vial is parallel to the
connecting line of B and C. Adjust B and
C so that the tubular vial is centered.

Preparation before Measurement T.O.2 | 17
5. After 2. is finished, turn collimation unit for 180°. If the tubular vial is still centered, the
leveling up of the instrument is finished. If the bubble strays from the center, perform
leveling up with the procedure for adjustment of tubular vial in "5.1 Tubular Vial".
3.4 Centering
Centering with
plumb bob 1. Tie the plumb bob wire to the hook on the central screw. Adjust the length of the wire so that the tip of the bob is 2 mm above ground.
2. Loosen the central screw and move the base so that the tip of the plumb bob is
precisely positioned to the ground point (when observed from two directions perpen-
dicular to each other).
Centering with
Optical plummet
1. Turn the knob of the eyepiece of the optical plummet so that the reticle is in focus; turn
thefocusingknobsothatthegroundpointaisinfocus. Then, loosenthe centralscrew
To ensure maximum measuring
precision, we recommend the
performance of the steps

Adjustment" before using this
instrument.

to translate the whole instrument (be sure not to turn the instrument) so that the
ground point coincides with the central point of the reticle. Retighten the central screw.
2. Perform precise leveling up of the instrument as described in "3.3 Leveling up of the
Instrument" and repeat the operation in 1. of "3.4 Centering", "Centering with Optical
plummet" until the instrument is precisely leveled up and the center of the reticle of
the optical plummet precisely coincides with the ground point as shown.
3.5 Collimation
Adjustment of
diopter 1. Aim with the telescope on a bright background.
2. Turn the eyepiece knob so that the cross hairs of the reticle are clearly seen.
Elimination of
optical parallax 1. Adjust the focusing knob so that the object forms image on the reticle.
2. Move your eyes up and down to see if the image of the object moves relative to the
graduation lines.
If it does not move, there is no optical parallax; otherwise turn the focusing knob to
eliminate the optical parallax.
3.6 Initial Settings
Before start measuring, please confirm all initial settings. Items in bold indicate factory
settings.
