User questions & answers

Question:	I have a Dewalt 18 volt rotary laser. Is this receiver compatible with it
Answer:	Designed for measurement of moisture content from the surface down to .25” (6.4mm) or .75” (19mm) deep inside wood "The above measurements are conservative. Example, I can place my hand on the opposite side of a 2x4 when taking a reading on the other side and affect the meter reading." FROM THE USER'S MANUAL 1. If the thickness of the piece of wood or other building material is greater than .75 inch (19mm), and you wish to get more of a full thickness rather than a shallow measurement, it is a good idea to take measurements in 3/4” mode on both sides and average the readings. "However, refer to my comment above regarding the 2x4. We have many companies and individuals that use Orions (and our previous MMC models) to measure 1.5 inch thick to 2.0 inch thick material, and are only measuring from one side (face).” 2. To prevent high or inaccurate readings, always have a minimum 1-inch (25mm) air gap underneath the piece of wood you are measuring. During this process make sure your hand is not directly underneath the wood you are measuring. Ron Smith - Wagner Meters Sales Manager
Question:	Would it work with pulsing line lasers
Answer:	First, regardless of the meter utilized, in general a meter’s accuracy is somewhat affected by the type and amount of treatment in the wood. Next, the Orion model 930 is well-suited for measuring wood with thicknesses up to 2”. IF there is very little moisture gradient in the thicker pine (3” and above) the depth of readings with the 930 will also represent the overall moisture content of the thicker pieces. To best answer these type of technical questions, we highly recommend you call Wagner Meters so their experts can help with your individual situation. Ron Smith - Wagner Meters
Question:	Does this receiver go with a Bosch laser
Answer:	For measuring the moisture in wood that has fairly smooth, flat surfaces at least 2.5 inches by 2.5 inches, one of Wagner’s non-pin Orion-model moisture meters would be fine. If you have rough, rounded surfaces, you may need to use a pin-type moisture meter with longer pins with insulated shafts on a slide hammer cabled to the actual meter.
Question:	will this work with 3d series laser level
Answer:	Although the Wagner Meters commitment to customer satisfaction dates back to its inception (the 1960s), the dawn of 2012 brought in a new era. Wagner Meters now offers a standard seven-year warranty policy on all Orion meters as well as the MMC and MMI moisture meters. Effective since January 1, 2012, Wagner Meters has implemented extended warranty protection on these models to ensure that woodworkers, manufacturers, installers, and inspectors can measure and monitor their wood products moisture content (MC) with renewed confidence.

Single Pythagorean Measurement

• Measure one hypotenuse side and the right angle side according to the Pythagorean theorem principle, and the instrument automatically calculates the length of the other right angle side that is displayed in the main display area. Note: When testing the Pythagorean method theorem, the two measurements mean that the reference point of the measurement must remain unchanged and the line between the two laser points and the three reference points must be a right-angled triangle, otherwise the calculation result differs significantly from the actual results.

Double Pythagorean Measurement

• Similar to the simple Pythagorean measurement, when measuring 2 hypotenuse edges and 1 right-hand edge, it must be ensured that the reference points of 3 measurements remain unchanged and the right-hand edge must be measured perpendicular to the target edge, otherwise the calculated results differ significantly from the actual ones Results.

Johnson Laser Detectors

When operating lasers outdoors on large jobsites, you typically can't see the beam. Laser detectors become a mandatory accessory to detect beam height and ensure the accuracy of your work.

Detectors must be chosen based on the color of the laser, the type of laser (line vs. rotary), and the style of detector required. Styles include single sided LED, single and dual style LCD, and machine mountable. All of the detectors shown here are for red beam rotary lasers (635/650nm).

Most Johnson Level detectors feature variable audible tones to tell you if you're too high, too low, or on grade. All detectors have a visual indicator to show you high/low/on grade, but the type of indicator varies by model. Read on to choose the perfect detector for your new Johnson laser!

Model #40-6705 LED Display Detector

Accurately detects laser beam (635/650nm) signals from rotary lasers. This detector features:

-LED Display: Three LED's light up to alert on grade / too high / too low.

-Audible Alert: The detector will beep when a laser signal is found but is too high or too low. The LED's will indicate which direction to move the detector to find grade. A solid tone will indicate when the detector is on grade.

-Low Battery Indicator: The detector will perform a battery check at startup and alert you to a low battery or exhausted battery.

-The accuracy of this detector is not adjustable, and is:

= 0.06" for distances < 165'.

= 0.10" for distances > 165'.

Grading

The 40-6715 dual sided display detector's LCD display shows on grade/high/low and lets the operator read either side of the detector for convenience. The detector accuracy can be reduced for rough work like this excavation or increased for fine work such as setting walls or posts.

Excavation / Site Prep

Here the 40-6535 laser is shown paired to the 40-6791 machine mountable detector. Super-strong rare earth magnets secure it, making placement on any steel surface simple. On this skid steer, the contractor located the detector on the boom arm because the boom arm moves roughly 1:1 with the bucket, but some contractors prefer to put it on the bucket directly. The choice is yours; regardless of where you locate it, installation is simple and pairing it with the 40-6792 remote display lets the operator see the display inside the cab.

Checking Floor Height

This contractor was building a bus repair terminal and just finished the exterior block walls. Concrete was coming in the next day, and they were using Johnson Level lasers and detectors to complete one final check of floor height prior to the concrete pour. The floors all had to have a specific slope for drainage, and Johnson Level's dual-slope rotaries and rotary detectors provided a simple way to complete this layout.
