1. Introduction

Please take the time to thoroughly read this instruction

manual. It will help you with the installation, maintenance,

and use of this product.

To the extent permitted by law Kistler does not accept

any liability if this instruction manual is not followed or

products other than those listed under Accessories are

used.

Kistler offers a wide range of products for use in

measuring technology:

 Piezoelectric sensors for measuring force, torque,

strain, pressure, acceleration, shock, vibration and

acoustic-emission

 Strain gage sensor systems for measuring force and

torque

2. Important Information

2.1 Disposal Instructions for Electrical and Electronic Equipment

Do not discard old electronic instruments in municipal

trash. For disposal at end of life, please return this

product to an authorized local electronic waste

disposal service or contact the nearest Kistler

Instrument sales office for return instructions.

2.2 Software Upgrades and Updates

Kistler may from time to time supply upgrades or updates

for embedded software. Such upgrades or updates must

always be installed.

Kistler declines any liability whatsoever for any direct or

consequential damage caused by products running on

embedded software which has not been upgraded or

updated with the latest software supplied.

Calibration Procedure

2523A_002-707e-11.14 Page 5

3. Calibration Procedure

3.1 Check Default Calibration Constants

a) Choose menu Calibration > Activate Calibration.

b) Enter password.

c) Choose menu Calibration > Target Calibration and

check calibration constants.

These are typical default values for standard Target

System Type 2523A:

d) Set ox = 0.0 and oy = 0.0

3.2 Install Paper Target

Place paper target approximately 0,5 m BEHIND the

Type 2523A target system. For best results use high

quality paper and install it in wooden frame. Never place

paper target in front of Type 2523A target system due to

distortion of signal by pieces of paper.

Mark center of paper target which serves as aiming point.

The recommended distance of the target system from the

muzzle is 100 m.

3.3 Measure Zeroing Shots

Perform measurement of zeroing shots in accordance

with the following requirements:

a) Use 5.56 NATO or similar small-caliber, highly

supersonic ammunition.

b) Carefully aim the weapon at the aiming point (center

of the target system).

c) Place the first shot as close as possible to the center

of target.

d) Place next shots left, right, up and down from the

center in cross-shape. Width and height of the cross

should be approximately 500 mm.

3.4 Determine Calibration Constants

a) After measurement open the Target Window:



Calibration Procedure

2523A_002-707e-11.14 Page 7

b) Measure the distance between center of the most

distant shots in X and Y direction in paper target and

compare it with relevant distances in electronic

target system (see parameter Rect in right column):

paper target electronic target

x_distance 455 mm 459,5 mm

y_distance

277 mm 280,4 mm

c) Calculation of new calibration constants kx, ky :

kx_new = kx_old × (x_distance_paper target) / (x_distance_electronic target)

kx_new = 1800 × 455 / 459,5 = 1 782

ky_new = ky_old × (y_distance_paper target) / (y_distance_electronic target)

ky_new = 1800 × 277 / 280,4 = 1 778

Set these new constants in Target Window:

Press button and enter new

calibration constants.

If two target systems are used, perform this

calibration for each target system and use individual

sets of calibration constants TS1 and TS2.

Otherwise set TS1 = TS2.

b) Calculation of offset calibration constants ox, oy

This calibration step is only required if the absolute

accuracy with respect to the aiming point is needed,

i.e. in the production testing of weapons.

For ammunition testing this calibration step is

usually not required, because only the relative

precision is evaluated.

Measure the distance in X and Y direction for the

same shot No. On the paper target and the

electronic target. Calculate and enter offset

calibration constants (ox, oy):

paper target electronic target

x_coordinate –34 mm –39 mm

y_coordinate –28 mm –8 mm

ox = (x_coordinate_paper target) - (y_coordinate_ electronic target)

ox = (–34) – (–39) = 5

oy = (y_coordinate_paper target) - (y_coordinate_ electronic target)

oy = (–28) – (–8) = –20

Check shifting of coordinates in the Target Window.

The new calibration constants are only adapted for the

current series of zeroing shots. To adapt them as new

default values, proceed according to section 3.5.

3.5 Update Default Calibration Constants

a) Use menu Calibration > Activate Calibration.

b) Enter password.

c) Use menu Calibration > Target Calibration and

set new calibration constants.

3.6 Verification

Replace paper target and repeat previous measurement

for verification of results.

In case of difference greater than the guaranteed

accuracy of the target system (see technical parameters)

repeat the calibration process. If problem persists,

contact Kistler Service.
