L-703SP Surface Plate Calibration System - Hardware Overview
This section describes the equipment and operation for calibrating surface plates using Hamar Laser’s L-703SP Surface
Plate Calibration Laser System. The system includes the laser, targets, fixtures, and software.
L-703S Spindle & Straightness Laser - Features and Setup
•Operating range of 50 ft. (15 m).
•Pitch and yaw angular adjustments with a resolution of .00002 in/ft (1.6 μm/m) and
adjustment range of ±0.36° (±.075 in/ft. or ± 6.26 mm/m).
•A .4995 in. (12.69 mm) mounting stud with the laser beam concentric to
< .0003 in. (0.008 mm).
•Under good environmental conditions, it is accurate to .0015 in. (0.075 mm) in 50 ft.
(15 m).
•Rechargeable Li-Ion battery with 20+ hours of battery life.
The L-703S is mounted directly in the A-703SP-LM Surface-Plate Mounting Fixture and aligned to the T-1297 Target
located at the end of the line segment. This provides a straight reference line for checking the flatness of the line segment
and the rest of the surface plate.
Applications include:
•Surface plate calibration
•Linear guideway straightness
•Flatness/straightness of large parts
L-703S Laser Control Panel and Functions
The I/O and Status LEDs
•Battery Status LED – green – normally it is off.
oBlinks when the battery is low.
oSolid green when the battery is charging. Turns off when the battery is fully charged.
•I/O LED – indicates the laser is turned on. This is also the mode indicator for the laser mode (see Laser Modes
below).
The On/Off Button
Press the I/O button once to turn it on and press and hold for 3 seconds to turn
it off. The I/O LED will illuminate when the power turns on.
L-703S Laser Modes
There are 2 laser modes:
1. Double-Blink Mode (default) – this is used for the T-1295/T-1296/T-1297 Targets
only. The I/O LED will blink twice and pause, blink twice and pause, and will do this
continuously.
2. Fixed (Continuous) Beam mode – the laser beam is turned on continuously and does not blink. This is used for
legacy targets using the R-358 Computer Interface or R-307/R-307V Readouts. The I/O LED will be continuously
on (no blinking).
To change the mode, press the I/O power button once – do not press and hold, just press one time.

A/C Connector
The L-703S comes with a rechargeable battery. The connector is shown in Figure 3
To connect it, line up the red dot on the A/C adapter plug with the red line on the
connector.
L-703S Angular Adjustments
The L-703S comes with pitch (vertical) and yaw (horizontal) angular adjustments to
adjust (tilt) the laser to align it to reference points or a rotation axis. The angular
adjustments have resolution of .00002 in/ft (0.0016 mm/m) and an adjustment range
of ±0.36° (±.075 in/ft or ± 6.26 mm/m)

L-703S Angular Adjustments – Returning Adjustments to the Center of their Range
To start an alignment, it is best to return the L-703S’s angular adjustments to the middle of their range. The middle of the
range is when the knob is flush with the overlay (see below). If the knob is unscrewed all the way, then knob will come
out but this will not harm the mechanism, so just screw it back in. If the knob is screwed in, then it will also go into the
face plate about .25 in. (10 mm).

L-703S Level Vials
When using the L-703S in machine tools, we typically will do measurements with the laser
at the NORMal position (12:00) and then rotated with the spindle 180 degrees to the
INverted position (6:00). There are level vials on the side of the laser to help you know if
the laser is directly at 12:00 or 6:00. However, this is not typically used in surface plate
calibration, so they are not used in this application.
To use the level, rotate the laser 90 degrees so that the control panel is on the side (i.e. at
3:00 or 9:00). Then slowly rotate the spindle until the bubble is centered in the circle.
This indicates the laser is ready to be aligned to the rotation axis.

L-703SP Surface Plate Calibration System - Hardware Overview
The T-1297 3-Axis Wireless Spindle & Straightness Target
Hamar Laser’s T-1297 3-Axis Wireless Spindle & Straightness Target is designed work with our L-703S Spindle &
Straightness Laser. With Bluetooth communication and multiple measuring axes, the T-1297 target is a multi-purpose
target that can be used for many different applications.
•Offers 2 measurement modes:
Center Mode - 2-axis center measurement for use with the
L-702SP’s through-beam.
Flatness (Scan) Mode - single-axis flatness measurement for use with our
series of auto-rotating lasers (L-730/L-740/\ L-702SP) in Scan Mode.
•PSD (Position Sensing Detector) Size:
.39 x .39 in. (10x10 mm) PSD
•Resolution (2 axis & 1 axis): .00001 in. (0.00025 mm)
•Wireless communication via Bluetooth Class 1 radio with 100 ft. (30 m) of
communication range.
•Accuracy: error is < 0.25% of the measurement
•PSD concentric to the mounting stud to < .0003 in. (0.008 mm).
•The T-1297 is designed so the measuring plane of the target is right at the face
plate of mounting stud, so when used with the A-1297 High-Accuracy Flatness-
Measuring Base, it achieves the highest accuracy possible.
•Accelerometer rotation axis (3rd axis) helps to orient the PSD sensor axes to the alignment axes of the spindle.
•Lithium polymer rechargeable battery with 14 hours of battery life.
How to Use the T-1297 Targets
The T-1297 Targets are designed for use with the L-703S in Double-Blink Mode (center/angular measurements) or
Scanning Beam Mode (flatness measurements using one of our scanning laser plane lasers). The targets have a .4995 in.
(12.69 mm) mounting stud for mounting spindles and fixtures, such as the A-1297 High-Accuracy Flatness Measuring
Base.
T-1297 Center Mode
This is the default mode when the target is turned on. It is recommended while in Center Mode to use the light/dust
shield, which is held in place with magnets. While in this mode, the values shown in Plane6 Software displays show the
center (offset) values of the target’s mounting stud relative to the laser beam. It follows the same sign convention as
shown on Page 36, Interpreting the + and – Signs in the Live Displays.

T-1297 Angular Mode - Optional
To use the T-1297 Targets in Angular Mode, the T-1295-AO-3 Lens or the A-1295-
AO-6 Lens need to be purchased. To use them, insert the lens into the target face
making sure line up the red or yellow dots at 12:00 when you insert it (see Figure 7).
Note: To use this in angular mode, this will require the purchase of the T-1295-AO-3/6
Angular Lens and Lathe10 or MultiTurn10 Software. Plane6 does not support Angular
Mode
Then click on the Angle button in Step 2 or 5 (see below) and the values will switch
to the angular display. Using the lens, converts the display readings in Lathe10 or
MultiTurn10 to angular values with the following raw-value resolution:
T-1295-AO-3: in/3 in. (mm/76.2 mm), which is converted in the software displays to:
in/ft or mm/m when you click on the Angle Button (see figure below).
T-1295-AO-6:in/ 6 in. (mm/152.4 mm), which is converted in the software displays to: in/ft (mm/m) when you click on
the Angle Button.
Note if the displays are left in Center Mode, then the values shown in the displays are raw values and will be in the units
shown above.
T-1297 Scanning Laser Mode - Optional
The T-1297 Targets can be converted to scanning targets to be used with the
L-702SP laser in Scanning Mode (or any L-730/L-740 Series lasers), which creates a
laser plane.
To change, the T-1297 target into Scanning Mode, make sure the L-702SP is turned off
or the laser beam is blocked. Then press and hold the Power Button (see Figure 9). The
ON-TGT LED will blink instead of being continuously on, as it is when it’s in 2-Axis
Center Mode. To return the T-1297 to 2-Axis Center Mode power down the target and turn it back on.
Note: You must also put MultiTurn10 into Scan Mode using the dropdown list in Step 3.
