Zircon Sonic Measure DM S50, DM S50L - Measuring Instrument Manual

INTRODUCTION

This tapeless, ultrasonic tool instantly measures interior room dimensions from 2 to 50 feet (.6 to 15 m) with one-touch simplicity. Function buttons provide prompting for easy calculations of area and volume. Model S50L also provides a laser circle identifying the target for additional verification.

FEATURES

READ button—to take a measurement
RECALL button—to display previously measured lengths
ft/m button—to select feet/inches or metric units
PWR button—to turn unit on and off
VOLUME button—for volume measurements
AREA button—for area measurements
LENGTH (and continuous reading) button— for taking a length measurement or for measuring continuously when trying to find a location at a certain distance
DOUBLE SEGMENT button—for taking two measurements to be added together

BATTERY INSTALLATION

1. Open battery door on back of case.
2. Connect a 9-volt battery to battery clip.
3. Insert battery into case and replace battery door.

When the low battery symbol comes on and stays on, it is time to change the battery. A dim display or inaccurate measurements also indicate a weak battery. Batteries last approximately 2 years under normal conditions, or for 8 hours of continuous laser use in the model S50L, with a fresh alkaline battery.

TAKING MEASUREMENTS

1. Turn on using PWR button. You will be in feet/inches mode or the last mode you used. You may select between ft./in. or metric measurement by pressing the ft/m button.
2. Select the type of measurement you wish to makeby pressing a button on the left.
3. Position and point unit squarely to the target. Measurement will start from back of the unit, which means the length of the tool is included in the number you see.
4. Press READ button to measure. Holding button down will allow continuous reading if you wish to move unit forward or back for positioning an item.
5. Each measurement erases previous one.
6. In the model DM S50L, pressing the READ button half way will turn on laser circle for adjusting your position to your target. Depressing fully will then take the measurement reading.
7. This unit will automatically turn itself off after 30 seconds of inactivity. When you press the PWR button to resume, the display will still show the last reading that was on the screen.

USING THE FUNCTION BUTTONS

DISPLAY

Ft/m button
This switch toggles you from feet/inches to metric units. You will not lose your readings when changing this mode.

LENGTH button (and CONTINUOUS function)
This tool will automatically come on in this mode for taking a single length measurement. If using other modes, you can press this button to get back to single length measurements.
You can hold the READ button down in this mode and move forward or backward to reach a certain distance for positioning of equipment.

AREA button
For area measurements, select this button and take a measurement across and lengthwise of a room. Remember that the length of the tool is included in your measurement, so place the back end of the unit against a wall on one side and shoot across to an open area of wall directly opposite. The first number will show on your screen and the blinking line will prompt you to take a second reading across the room in the other direction. The resulting calculation will show on the screen.

VOLUME button
For volume measurements, you follow the same steps selecting the VOLUME function button and taking measurements following the prompting bars on the display. Be sure to place the tool base against the surface and point perpendicular to the wall. If unsure of any of the three readings, press the RECALL button and you can step back through each of them with a flashing direction bar guiding your selection. Each number can be re-shot using this "Recall" mode and pressing the READ button while that segment bar is flashing.

DOUBLE SEGMENT button
Press this button before measuring and you will be able to take two measurements that will be automatically added together. This is particularly helpful when measuring distances longer than 50 feet (15 m). From a marked spot in the middle of an area, you can take a reading in opposite directions to measure a longer space.

RECALL button
When taking a square footage, volume, or double segment measurement, you can use this button to scan back through any of the previous segments to check a number. Each segment bar will flash to show you which number you are seeing and if you are concerned with that particular length being accurate, you can take a replacement measurement by pressing the READ button again while it is flashing. It will then replace the flashing segment's number with your new reading and update your calculations.

HINTS

1. Each measurement clears the preceding one orgroup of area/volume measurements. You can also clear a measurement by pressing a mode button.
2. Ultrasonic signals radiate in a cone shape, approximately ±5° from center. To get accurate readings you must measure to a target with a large, flat, hard area such as a wall.
3. Obstacles in the signal's path, such as furniture anddraperies, interfere with the signal, producing errors or inaccurate readings.
4. Accuracy will vary depending on environmentalconditions.
5. The DM S50/S50L cannot measure through glass, but will measure TO glass.
6. "Err" will be displayed if the target is not a goodultrasonic reflector (e.g., thick carpet or draperies) or the result exceeds the working range of the unit.

The DM S50L Sonic Measure has been outfitted with a Class IIIa laser. Avoid direct eye exposure at all times. Wavelength: 635 nm – 650 nm. Power: Class IIIa (<5 mW peak power)
