PENTAX MD-14, MD-20 Electronic Distance Meter Instruction Manual

PENTAX
ELECTRONIC DISTANCE METER
MD-14 MD-20
INSTRUCTION MANUAL
ASAHI PRECISION CO. LTD.
The PENTAX Electronic Distamemeter MD-14/MD-20
are of the highest quality and design. We therefore,
recommend that you read the instruction manual
very carefully so that you will appreciate the full
capabilities of your PENTAX precision instrument,
and ensure years of trouble-free operation.
To prevent accidental damage to your PENTAX
EDM, please adhere to the following notes which
have been constructed to help you in maintaining
your instrument in a precise functioning condition.
Environmental Conditions
e Avoid to aim the objective lens directly at the
sun. Direct sunlight, focused through the objec-
tive lens, may cause the damage to internal
components.
e Avoid leaving it at high temperatures for a long
time. High internal temperatures may cause de-
terioration and affect its distance measuring
performance.
Avoid using it on rainy days because it contains
electrical parts, or keep it shielded from the rain
as much as possible.
* Avoid subjecting it to rapid changes of tempera-
ture, i.e. do not suddenly carry it to the cold open
air from a warm place. This causes distortion or
generates condensation inside. This will cause
temporary deterioration of distance measuring
performance.
e In poor weather conditions, distance measure-
ment requires more time and an increase in the
quantity of prisms.
Battery Charging
* When charging the on-board battery MB18 or the
external battery {MB22), be sure to use the
PENTAX on-board battery charger (MC-17, MC-16)
or the PENTAX external battery charger (MC-22)
respectively.
* Charge on-board battery at the room tempera-
tures of +10--400°C/ + 50--+104°F (external battery
0--+45"C/+32°~113°F.) Otherwise, normal charge
may not be possible.
Shutdown
# After use, clean away dust and moisture and
store in dry place not subject to considerable
temperature change.
e When not in use for extended periods, take it out
of the case occasionally and expose it to the fresh
air.
When not in use for extended periods, be sure to
remove the on-board battery from the instrument
and store it seperately. Also, take the instrument
out of the case occasionaly and expose it to the
fresh air.
Transport
e Be careful not to subject it to impact or vibration
during transport by a contractor, and use a good
packing material.
a Transport In carrying case supplied.
Attaching Tripod
e When attaching or detaching the instrument to or
from the tripod, be sure to hold it with one hand.
The quality of tripod used is very important for
measuring accuracy.
Other Points
e |f repair is necessary, contact your dealer. Do not
attempt to repair it yourself.
e lt is recommended that the instrument be
checked before going to field work, particularly
in case that the instrument is not in use for an
extended period.
Avoid to disassemble the instrument by yourself
even if the defect is found.

Data communication with Data collector
When used with TH-E Series Electronic Theodolites,
MD-14 can obtain angle data from the theodolite to
measure horizontal and vertical distances without
complex conversion equations (similar to a Total
Station system). In addition, Data Collector DC-1 can
be used to communicate data with a computer via
the R5-232C interface and bidirectional communica-
tions system. Data collected in field measurements
can also be stored in the DC-1 Data Collector for
later transmission to a base computer, thereby
automating and rationalizing a series of measure-
ments.
EM Refer to the Data Collector instruction manual for
specifics on Data Collector connection and
operation,
B Communications parameters between the Data
Collector and host computer system will vary
with the computer system.
Refer to the communications protocols of the

Maintenance
(T) After using the instrument, wipe off dust and
moisture and store it in its case.
(7) When cleaning the exposed parts, first remove
dust with the cleaning brush, then gently wipe
with a soft cloth.
(A) To clean the lens surfaces, first remove dust
clean cotton cloth to which a small amount of
alcohol has been applied. Be sure the cloth used
Is clean.
[2] Storing
Store the instrument in the plastic case shown.
№ Be sure not to store the instrument with the
on-board battery
7. Inspection and Adjustment
[1] Offset Constant
The offset constant can be obtained by checking the
measuring accuracy on the certified base line. It can
also be obtained in the following way.
E Remember that any error in prism position, base
line accuracy, collimation error, atmospheric
correction, or atmospheric refraction and earth
curvature will affect the precision of the inspec-
tion.
1) Checking
(1) Locate points A, B and C at about 50m intervals
on the even ground
©) Set up the instrument at point A, and measure
distances AB and AC.
(3) Set up the instrument at point B, and measure
the distance BC.
(4) Obtain the offset constant (К):
K = AC — (AB : BC)
M After above checking is completed, please
consult with your local dealer when the offset
constant of nearly 0 is not obtained.
Instrument Prism Prism

Instrument Prism
2 e _ 9
Checking of Alignment of Beam
Axis and Line of Sight
Use the procedure below to check if the beam axis
and the ling of sight is aligned.
(1) Set the instrument and a prism about 1 m apart.
They should be on a straight line.
about 1m
(2) Turn the power switch on.
(3) Measure the distance with the MEAS and TR
keys.
(4) Use the telescope and horizontal tangent screws
to sight the EDM towards the point where the
-signal strength is maximum,
(5) Look through the collimation scope eyepiece. A
red image should be visible. There will be no
problem with EDM accuracy if the red image
almost overlaps the center circle of the collima-
tion scope pattern.
- Red image
If this is not the case, contact your Pentax dealer.
[3] Parallelism of the theodolite
line of sight and beam axis
1) Standard mount type (MY-01)
This adjustment is not necessary if target colli-
mation for theodolite angle measurements and
MD prism collimation for distance measurements
are performed separately. This adjustment is
necessary, however, if target collimation of the
theodolite is used to eliminate the horizontal axis
collimation (using the direction tangent screws)
needed for distance measurement.
Adjustment
(1) Set the prism and target about 50 m away from
the instruments, and collimate the theodolite on
the target.
(3) Use the vertical tangent screw to collimate the
prism (vertical).
(3) Loosen the mount adaptor lock bolt (one each on
right and left) with a hexagonal wrench {large}.
@ Turn the mount adaptor adjustment screws to
collimate the prism.
(5) Tighten the lock bolts.
EM Tighten one adjustment screw and then the
