Powered by 2 x AA Batteries
Battery status will be shown on the initial screen .
In case if battery icon is displayed continuously, it shows the battery is about 1,000 measured times left .
The low power indicator will twinkle when the battery is low .
To change new batteries, remove the back lid and observe the correct polarity when installing new batteries, then close the back lid.

Overview of TIS LD40

Overview for Screen

TIS-LD40-Metre-Laser-Distance-Meter-FIG-13

The working range and accuracy depend on how well the energy of the laser is reflected from the surface (mostly comes from scattered light) and the target reflectivity. The brightness of the laser point to ambient light intensity or the use of a target plate (Kodak White) may help increase the working range and the stability of accuracy.
In favourable conditions, accuracy could be in #1.5 mm(2) and a deviation influence of $0.25mm/m must be taken into account after ten meters.
Unfavourable conditions, such as bright sunlight, rough surfaces, very short distances, or a poor and extra strong reflected signal may cause the deviation to reach over 10mm and also may bring an ambiguous cycle which may lead the measures to an unexpected result.

Turn on your TIS LD40

Before starting, please make sure the battery is installed properly. For installing method, please read page 1.
Press once to activate.
The initial screen will flash seconds for to check the status.
After checking, a standby screen will be displayed.

Measuring Distance

CAUTION!
- The laser will be emitted when you turn it on.
- Check the icon on the upper-left corner to check if the laser is emitted.
If the laser is not activated, press to enable the laser.
Then, move the laser dot of the unit onto your target, and try to keep the dot on the target.
press to activate the measure.
The whole measure will be finished when a beep is heard or the measured result appears on the main screen.
The laser will be turned off after measuring.

Add your measures

calcuating the summary of measurements is simple only with a few buttons.
Once you have your first measurements, press to save into memory (temporarily saved)
Thon finds your next desired distance, once you find it, press again.
The summary will display on the main screen and you can see what you have added.

Subtract your measures

Calculating the different measurements is simple.
Once you have your first measurements, press to save into memory (temporarily saved)
Then find your desired distance, once you find it, press again.
The result will display on the main screen and you can see what you have subtracted.

Dyna-Measuring (Continuous Measuring)

To activate Dyna Measuring (continuous measure), hold then it will jump to Dyna Measuring mode.
When entering Dyna Measuring mode, the laser beam will be also activated.
To pause, please press or
Maximum and Minimum values will be displayed on the screen
To quit Dyna Measuring to go back to normal mode, press or

Measuring reference

By default, the reference is set at the rear.
The unit has three references: front, Tripod thread, and rear.
To change reference, press , and each press will take effect. The changing sequence is Front → Tripod thread → and rear.

a. Area Measurement
- Please press once for enabling Area measuring.
- The laser will be activated when entering the Area measuring
- Follow the instructions on the main screen to measure width and length.
- Once you finish all the instructions, the Area is shown on the screen.
- To change the display unit, press
b. Volume Measurement
- Press twice to enter the volume measuring.
- Press to enable the laser beam.
- Follow the instructions on the main screen to measure width, length and height.
- Once you finish all the instructions, the volume is shown on the screen.
- To change the display unit, press
c. Indirect Measurement
- Press to enter Indirect measuring.
- All the calculation is based on the Pythagorean theorem (a’+b’=c*) to measure height indirectly.
- Press › to enable the laser beam and follow the instructions on the screen to get the slang range and horizon range then the height will be displayed on the screen.
