4.2 Remove and recharge the battery
Removing the battery
Press the buckle and pull out the battery.
Recharging the battery:
Insert the charger jack into the plug of
the battery;
insert the charger into a 100VAC-
240VAC (50-60Hz) plug,
check if the the LED is lite (RED).
As the recharge is completed, the LED turns
green. This takes about 3-4 hours.
Caution: the battery charger is intended for indoor use only.
Note:
1. New batteries need to be fully charged and discharged several times to reach their
best performances; the first charge should be not less than 10 hours, continuing the
charge even when the led is green;
3. LED behavior:
- RED lit: charging in progress;
- GREEN lit: charging completed;
- RED Flashing: no-loading, connection failed or defective battery.

4.4 Bar-code leveling staff
Digital level D1 electronic readings require a specific bar-code staff. The best
leveling precision is reached using accurate fiberglass one section bar-code
staffs. Anyway even aluminium foldable staff and the coded band included in
the basic set can be used for less accurate leveling operations.
Note
Only Stonex barcoded staff must be used with D1; staffs from any other producer give
no electronic reading of the staff itself.

Stonex D1 Digital Level –User Guide 11
5. General operation
5.1 Instrument set up
Position a solid tripod –aluminium or wooden –on a suitable place around in
the middle of the levelling base, and firmly fix it on the ground; the tripod
head should be leveled as flat as possible, to minimize the levelling procedure
using the bubble on the instrument.
Carefully take the instrument from the transport case and place it on the tripod
head. Support it with one hand, and tighten the 5/8” centering screw of the
tripod on the bottom of the unit to make sure it is secured to the tripod.
5.2 Levelling-up
Once the instrument is fixed on the tripod, turn the footscrews to make it
perfectly leveled. As the bubble is in the middle of the circular level, the
instrument is pretty leveled.
The bubble image can be directly observed through the mirror (N. 6, pag.7)
5.3 Sighting and focusing
Before to aim to the staff, it is necessary to focus the telescope crosshair. Aim
the telescope toward a bright background and turn the eyepiece ring (N. 12,
pag. 7) until the crosshair appears sharp and absolutely black.
Then aim to the staff sighting through the gunsights (N. 11, pag.7), and turn
the focusing knob (N.18, pag.7) until the staff image appears sharp and is free
from parallax with respect to the crosshair, i.e. there should be no apparent
movement between the horizontal crosshair and a staff graduation when the
observer moves his eye slightly up and down.
Finally turn the instrument with the horizontal movement knob (N.8, pag.7)
unitl the vertical crosshair is exactly aimed on to the centre of the staff.
5.4 Optical reading on staff
After sighting the staff, check whether the circular bubble is in the middle, and
press the compensator button (N.10, pag.7) to check whether the
compensator is working properly.
Read out the value through eyepiece according to the position of horizontal
crosshair on the staff.

Stonex D1 Digital Level –User Guide 12
Then read out the millimeter value on the display which is within a centimeter
interval and relevant to horizontal crosshair. When strong wind or ground
vibration happens, the Surveyor should support the center of tripod with
hands so as to make it more stable.
In order to compute the horizontal distance, the following procedure is
necessary:
Read out the values of top line and bottom line of stadia hairs. Calculate the
distance from instrument to staff, that is, L=100×l.
Note:
l: Distance between top line and bottom line in the cross hairs.
L: The distance from target to instrument.
100: Multiplication factor of telescope.
In the right figure, the difference between the upper (1.648) and the bottom
(1.588) line is 0.060m, thus the horizontal distance is 0.060×100=6.0m.
Optical reading of horizontal crosshair is: 1.618m.
Optical reading of top line is: 1.648m.
Optical reading of bottom line is: 1.588m.
Imaging information on staff:
Optical reading of elevation is: 1.618m.
Horizontal distance is: 6.0m.
5.5 Azimuth measuring
Collimate target A with vertical crosshair, the angle value of horizontal index
plate is X, rotate the instrument, and collimate target B, the angle value of
horizontal index plate is Y, then ∠AOB=X-Y.

5.6 Electronic reading
Switch on the instrument by long pressing the “POWER” button, and aim to
the staff with optical sight. Turn focusing knob until the staff image appears
sharp and is free from parallax with respect to the crosshair.
The staff must be turned on the bar code side.
Turn tangent screw to place vertical crosshair of reticle in the middle of the
staff. If the horizontal crosshair of the reticle is not perpendicular to staff, move
the staff to make it through. Press “MEAS” button to start measuring.
After measuring result is obtained, press “height” button to enter “height
difference” display, press “MEAS” button again, the instrument calculates and
displays elevation difference automatically.
Press “backlight” button to turn on or off backlight of the screen. After
initiating the instrument, short press “POWER” button to turn on or off battery
indicator. After measurement complete, long press “POWER” button to power
off.
