Postax for DPII
Postax is used for determining a trees relative position to a plot center.
Plot Coordinates, Plot Id, Plot Radius, Coordinate system, Distances,
Species, Diameters and Heights are entered into the program.
With the received distances and diameter, coordinates, Cartesian and
Polar, for the center of the tree relative to a plot center are calculated
and shown in the display continuously.
The distance from the tree to the plot center can be measured with the
Postex VL5 instrument and transfered to the DPII caliper or using the
Postex DME instrument directly attached to the caliper.

Quick Guide Postex System
Transponders
Three (3) transponders work together in the Postex system. Each
transponder has its unique setting. For identification, each transponder
has its unique color ring.
The transponders have ultrasound transmitters and a receiver that
communicates with the Postex instrument. The transponders can be
used both for aimed/direct measuring and for circular measuring with
the 360 degree adapter. If you need to use a transponder for height
measuring, remove Transponder A WHITE from the adapter at the tripod
rack. It is important not to move the position of the arm when removing
the transponder. The transponders WHITE, GREEN and BLACK should
not be mixed up, and they should always be consistently positioned in
its adaptor.
The Transponders are equipped with a beep signal, indicating ON or OFF
status. The Transponders have no switch. The Postex instrument is used
as a remote control to turn off and on. When turned on, the
Transponder stays active for app. 20 minutes. After 20 minutes of
inactivity, the transponder will turn itself OFF.
Each transponder uses one alkaline 1.5 volt AA battery placed under the
battery lid

Turn transponder on/off
Start the T3 transponder by holding the ultrasonic transceiver on the
Postex instrument close to the centre of the transponder. If using the
Postex VL5 Instrument press the DME button. If using the Postex DME
Instrument; start a distance measurement in the caliper program. Await
two (2) short beeps from the transponder. The T3 transponder is now
turned on and will remain active in ON mode for approx. 20 minutes
before automatic turn off (battery saving function). To turn the T3
transponder off (OFF), repeat the procedure and wait for four (4) beep
signals
Adapters
Four (4) adapters are included in a Postex system.
Each transponder has an adapter. The fourth
adapter is placed in the tripod center and used to
place the bubble/libell on.
The adapter allows the ultrasonic signals to spread in
a 360 degrees circle and enables the user to measure from any
position from the tripod,(within the distance limit).

Setting up the tripod
1. Position the tripod
and assemble and
fold down the
telescopic arms on
the tripod rack
with the three
transponders
mounted.
2. Security check:
Test the arms to
be equal in length
by aiming the
Postex instrument
facing down in the
adapter placed in
the centre.
Measure the
distances with the
instrument using
the ultrasound
method.

NOTE! It is of great importance that the distances to the
transponders from the centre are equal. Divergences should
never exceed 1cm/0.39”. Also note that due to the height of the
adapter on the tripod, distances greater than the arm’s length
will be obtained (arm length = centre of the tripod to center of
the adapter = 115.5cm/45.04”)
3. Place rack arms at horizontal level.
4. Aim transponder C facing north by aiming a compass through the
tripod centre and through transponder C.
If aiming transponder C (Black) towards North, the local
coordinate system has a Y axis north-south and an X axis
east-west (Image 1). NOTE! In land survey contexts, the X
axis can sometimes be stated as north-south.
5. Measure the distances by aiming the Postex instrument towards the
plot centre where the tripod is placed, with the backside of the
instrument at the tree stem (image 2). Press the DME button on the
Postex VL5 and hold the instrument steady until the three distance
results are featured in the Postex display.
Max radius with the T3 transponders mounted on the tripod is, 0.00m-
15.00m/0.00ft-50.00ft
Calibration of Postex DME
Ultrasonic pulses travel with different speed. In open terrain and without
disturbing objects between the instrument and the transponder,
distances up to 40 m or more can be measured to the T3 transponder.
Always calibrate the ultrasound in the current temperature and make
sure that the Postex has the same temperature as the air where
measurements are to be made. To obtain maximum precision it is
recommended to control and if necessary calibrate the instrument
periodically, preferably daily.
To obtain maximum accuracy level in ultrasound measuring operations,
the instrument needs to be calibrated.
1. Make sure the instrument has ambient temperature –not colder
and not warmer.
2. Measure the exact distance of 10m/32.8 feet with a tape or
similar.
3. Place the T3 transponder at the finish of the exact 10 m distance.
4. In the caliper and the Postax program go to Settings->System-
>Test->DpDme.
5. Start the T3 transponder by holding the ultrasonic transceiver on
the Postex close to the centre of the transponder and use the
DME function in the caliper. Wait for two (2) short beep signals
from the transponder. The T3 transponder is now turned on and

will be in ON mode for approx. 20 minutes before automatic turn
off. To turn the transponder OFF, repeat the procedure and wait
for four (4) short beep signals..
6. Go to the zero point on the measured distance and aim the front
of the Postex instrument to the transponder.
7. Press Escape in the caliper..
8. Select CAL and press Enter to confirm.
9. When the digits 10.00 are shown in the display, the calibration of
the Postex ultrasound is ready.
The temperature sensor in the Postex must be given time to adjust to
ambient temperature. The adjustment can take more than 10 minutes.
If the Postex is in a pocket with a temperature of +15°C and the outside
temperature is at -5°C, the measuring result will be 10.40 m instead of
the correct 10.00 m. the temperature pending measuring fault at 10.00
m is approx. 2 cm/°C.
It is important that the temperature sensor is given enough time to
correctly determine the ambient temperature. If you are carrying the
instrument in your pocket you might have to allow up to 10 minutes
before you obtain accurate measurement results.
The error will decrease rapidly, but the final accuracy might take up to
10 minutes to achieve. Taking this into account, calibrating the
instrument before the sensor has had time to stabilize will make the
error “permanent”. The display will then show the correct 30.00 feet for
a short while, but a few minutes later the measurements will be
inaccurate.
CALIBRATING WITH T3 TRANSPONDER ON AN ADAPTER
When the T3 transponder is mounted on an adapter the ultrasound is
spread in a 360 - degrees circle. Measuring can be done from any
optional position to the T3 transponder. The ultrasound travels three (3)
extra centimetres/1,17”, and the measurement result should always be
read in the front of the Postex display on the Postex instrument.
An alternative way of performing calibration is to attach a measuring
tape that passes through the T3 transponder centre at one (1) meter,
and then calibrate the Postex at eleven (11) meters/36,8ft.
