Frequently Asked Questions - KH 2927-1 POWERFIX

How do I turn on the Powerfix KH 2927-1 rangefinder?

Press the ON/OFF button (labeled ⑩) to switch the device on. The display will activate.

What is the measurement range of this device?

The measurement range is 0.6 m to 16 m (approximately 2 ft to 53 ft). If the distance is outside this range, 'Error' will appear on the display.

How can I switch between meters and feet/inches?

Press the FT/M button (labeled ④) to toggle between metric (meters) and imperial (feet/inches) measurement units.

What should I do if the battery symbol appears on the display?

Replace the 9V block battery (6LR61) as soon as possible. A weak battery can cause inaccurate measurements. Follow the instructions in the 'Inserting the battery' section.

Can I measure areas and volumes with this rangefinder?

Yes. Press the MODE button (labeled ⑨) repeatedly to select area or volume measurement mode. Follow the on-screen prompts to measure length, width, and height.

How do I add multiple distances together?

Measure a distance, then press the RECALL button (labeled ⑤) to add it. A '+' appears. Measure the next distance, and the sum will be shown in the lower line. Repeat as needed. To exit, press MODE.

Is it safe to look into the laser beam?

No. The device contains a Class 2 laser. Never stare into the beam or point it at people or animals. Laser radiation can cause serious eye damage.

Intended Usage

This appliance is intended for the measuring of distances and for the calculation of areas and volumes. The appliance is intended for domestic use only. Do not use it for commercial purposes.

Safety instructions

Risk of personal injury!

• Do not use the appliance at locations where there is a risk of fire or explosion, e.g. in the vicinity of inflammable liquids or gases.

Inserting the battery

1. Open the battery compartment ⑦ at the rear of the Ultrasonic Distance Meter.
2. Place the 9V block battery onto the contacts. Pay heed to the correct polarity.
3. Lay the 9V block battery into the battery compartment ⑦.

Warning:

Ensure that the wires are not trapped in any way. This could irreparably damage the appliance.

1. Close the battery compartment ⑦. The battery compartment lid must audibly engage.

Measuring distances

1. Switch the appliance on by pressing the button ON/OFF ⑩.
2. If necessary, press the MODE ⑨ button several times until the indicator (distance measurement) appears in the display.
3. To switch between metric (Meter M) and Anglo American (Feet'/Inch'') measurement units, press the button FT/M ④.
4. Hold the appliance upright towards the wall to which you wish to measure the distance. The ultrasound sender/receiver ② must be at a right angle to the wall. For this, use the spirit level ⑧:

The bubble in the glass ⑧ must stand between the marking lines (see Fig.1).

1. Press the button READ ⑪ briefly. A laser point is projected and an acoustic signal sounds. Hold the appliance in this position until the measured distance appears in the display ⑫.

(i) Note:

Measurements start at the measurement point ⑥! Should the measurement lie outside the measurement range, "Error" or an illogical number appear in the display. The measurement range lies between 0,6 m (ca.2') and 16 m (ca.53').

Take note of the following illustrations:

Fig. 1

Fig. 2

The further you are from the wall, the wider is the area (a) that the Distance Meter must measure by ultrasound (Fig. 2). Therefore, take care to ensure that the Distance Meter is always directed at a right angle towards a level surface (Fig. 1 and 3). Ensure that there are no objects positioned within the measurement area.

False!
