1.0 INTRODUCTION

The Check-Line QB-LED is a hand-held, battery-powered stroboscope featuring

extremely bright LEDs for the highest light output in its class. Designed for machinery

observation, visual inspection and motion analysis, its robust design is suitable for use in

the toughest industrial environments.

1.1 Scope of Delivery

Check that you have received all of the following:

• Stroboscope: QB-LED design (40 LEDs, no laser)

or QBS-LED design (118 LEDs, with laser)

• Operating instructions

• Calibration certicate

• Charger with connector set

• Trigger plug

• Reective tapes (QBS-LED only)

• Handle

• Foam-tted, plastic carrying case

Note: This device is suitable for use in residential, commercial and industrial area.

1.2 Precautions when using

Risk of injury! Laser class 2: The stroboscope QBS-LED is tted with a

class 2 laser. This is located at the front of the device. The laser beam can damage

eyes. For this reason, do not stare directly at the laser beam and never direct it at

people or animals. Wavelength: 650 nm, output: 1 mW.

Risk of Injury! Flashing lights can cause retina damage: The

stroboscope QB-LED and QBS-LED versions are tted with 40/118 LEDs

respectively. These produce potentially dangerous optical radiation, which can

cause retina damage. Do not stare directly at the light and never direct it at people

or animals.

Risk of injury! Moving objects appear still or in slow motion in stroboscopic

light. Do not touch such objects under any circumstance.

Risk of injury! The device may not be used in potentially explosive areas.

Risk of injury! Stroboscopic light can trigger epileptic seizures in

persons at risk.

3.0 SETUP

3.1 Connectors (see Fig. 1)

3.2 Set-up steps

Please follow the steps below when setting up the device:

1. Charge the device by plugginh the charger into the CHARGE (A) socket to the

rear of the device (see Fig. 1)

2. Direct the device at a moving object and switch it on. Turn the selector switch (E)

one notch to the left to “FREQUENCY.”

The device will start to ash immediately. For this reason, do not

direct it at people or animals.

NOTE: The device will ash at the frequency that was set most recently. The display

shows the selected ash frequency in the unit that was set most recently (rpm, Hz or

FPM). If the ash frequency coincides with the frequency of the motion, a static

image appears.

3.3 Connect the trigger

The device has the option of being externally triggered.

DO NOT trigger the device with signals in excess or 300,000 FPM.

Material damage may occur.

NOTE: Use only original material from the manufacturer to connect the trigger signal.

The trigger input is isolated and is suitable for PNP

and NPN signals. A trigger plug suitable for this

input socket is included with the device.

1. Plug the trigger plug into the input socket

INPUT (B).

2. Screw in trigger plug.

3. Assign the connection socket as per Fig. 3.

NOTE: The device must be manually switched

between external and internal trigger signals (see

How select an internal/external trigger, page 9).

4.0 OPERATION

Note: This device comes in two versions.

• QB-LED (40 LEDs, no laser)

• QBS-LED (118 LEDs, with laser)

Both versions are available in Standard and Pro modes (see section 4.3, Standard mode

and section 4.4, Pro mode).

4.1 Controls

No. Term Description

(D Rotary/Push Knob • Turn the knob to select the value and push to conrm. The

adjustment increment depends upon the rotational speed.

• Turning the knob while simultaneously pushing it, effects the

adjustment increment in steps of 100.

• The ash can be turned off by pushing the knob once and

turned on again by pushing the knob once again.

(E) Selector Switch Choose between OFF, FREQUENCY, BRIGHT, MENU and LASER

(QBS-LED version) by turning the switch to the desired position

(3) MENU PHASE deg:

0…359

Delay setting between the trigger signal

and ash (in degrees relative to the

frequency

Phase sift (PHASE in deg)

Phase shift setting (in degrees, relative to the frequency) between the trigger signal and ash. This value

allows a xed angle to be set between the trigger signal and ash.

• Example without external connection: The viewing position can be extremely precisely adjusted without

changing the ash frequency. You can shift the viewing position within a movement cycle.

• Example with external connection: The external trigger signal is triggered before the desired observation

point (= ash position of the stroboscope). This would mean that the connected stroboscope would

regularly ash too early. The PHASE deg setting adjusts the delay, altering the ash position of the

stroboscope by a set angle. This setting is not affected by the current rotational speed, which means that

the stroboscope will ash at the desired position even during rotational speed uctuations or during the

start-up period.

How to select in the MENU

1. Turn the selector switch (E) to the MENU position.

2. Select which parameter (e.g. PHASE deg) you want to change by turning the rotary/push knob (D).

3. Push the rotary/push knob (D) to conrm a parameter selection. The number shown in the display will

begin to ash.

4. Select the desired value by turning the rotary/push knob (D.)

5. Conrm and exit selection by pushing the rotary/push knob (D).

The setting is now active.

NOTE: The display and adjustable value can be changed by turning the rotary/push knob (D).
