Getting started

4.1 Power supply
The PCE-LES 103 / 103UV is a handheld device powered by a 7.4 V 2400 mAh Li- Ion battery that allows it to work without connecting it to any power supply when it is sufficiently charged.
When the battery is discharged, charge it by connecting the optionally available USB charger to the 240 V AC net and the USB plug to the USB connector of the device. The charger will provide a stable 5 V DC output to charge the battery inside the device. Alternatively, the meter can also be charged via the USB port of your computer.
The device can work connected to the power supply or with no external connection if the battery is charged. In both cases, the operation will be the same, as described in the next sections of this manual.

Operation

5.1 Power the device on/off
To turn on the device, press and hold the Power key for approx. 2 seconds. First, you will see the power on screen (figure 2) and after 2 seconds, the device will show the main screen (figure 3) and will be ready to use. After turning it on, the device will load the last configuration values used as well as the frequency, duty cycle and phase shift values selected the last time it was used.
To turn off the device, press and hold the Power key. A countdown will be displayed as long as the Power key is pressed. When the countdown reaches 0, the device will turn off.
5.2 Measurement
5.2.1 Change the flash unit
From the main screen of the device, press the OK key to switch the flash unit. You can select Hertz (Hz) or flashes per minute (FPM) (figure 4). Press the OK key again to switch to the previous unit.
5.2.2 Adjust the flash frequency
The frequency at which the device LEDs will flash can be adjusted by using one of the following keys:

hold to increase more quickly
| A single keystroke decreases the flash frequency / FPM by 0.01 /press and hold to decrease more quickly

5.2.3 Fine parameter adjustment in quick mode
You can perform a fine frequency adjustment by pressing the Quick key. When the Quick key is pressed, fine frequency adjustment mode will be activated. You will see a digit in the frequency  value highlighted in orange, as shown in figure 5. You can then press the Up / Down keys to increase / decrease that digit by 1. Press the Right or Left key to move through every digit of the value and adjust each digit. Once the desired value has been entered, press the OK key and the device will be set to the entered frequency. Once OK has been pressed, the next parameter (duty cycle) can be modified following the same procedure as with the frequency. You can modify the duty cycle now by pressing the Up/Down keys to increase/decrease each digit and using the Right/Left keys to navigate to other digits. Press OK to confirm the entered value for the duty cycle or press Back to return to frequency modification mode. If you press OK, the next parameter (phase shift) can be modified in the same way as the two previous parameters. Phase shift can be modified like the duty cycle and frequency. Use the Up/Down keys to increase/decrease the digit and Left/Right to navigate to other digits within the parameter. You can press OK to confirm the entered phase shift, so the device will return to the main screen or press BACK to go to duty cycle modification mode.
5.2.4 Switch the LEDs on/off
You can enable/disable the LEDs from any menu / screen just by pressing the LED ON/OFF key. When the device is in the main screen, the colour of the frequency reading will change from white (LEDs off) to orange (LEDs on) when the LED ON/OFF key is pressed. Attention: Avoid direct eye contact with the LED light. Do no look into the lightemitting diodes while these are on.
