Fauser Light Analyser ZadPad Measuring Device
Introduction
ZadPad is a measuring device for different physical metrics, selectable via the attached probes. Fast and precise data acquisition and high-performance processing power offer extensive possibilities of data acquisition and analysis for a hand-held measuring device. Also, time and frequency domain analysis of the measurement signals are displayed as a chart. The measurement data can be saved on the internal USB drive (future firmware version).

Turn on/off
The ZadPad is turned on through the On/Off button ➊ and turned off by Menu→Off. If no software turns off is possible, the On/Off button can be pressed for 5 seconds. If no key is pressed for the selected Auto-Power-Off time or the battery falls to minimum voltage ZadPad turns off automatically.
Charging the battery and battery indicator
The ZadPad has a rechargeable Lithium-Ion battery. The operating time
significantly depends on se and settings (e.g. backlight). Operation time is
between 8 and 20 hours. The battery voltage level is shown in the Header info
screen ➎. Charging is done through the USB port ➋ with a power supply of 5
V/1500 mA. This corresponds to the standard charger for mobile devices. Never
use other chargers; this may lead to damage to the ZadPad. Never charge in the
vicinity of combustible material or gases. Never charge batteries unattended!
Recharge devise approximately every 6 months in case of prolonged non-usage.
Charging is done once the charger is plugged in; this is visible through the
light of the charging indicator- LED ➍. The charging time is approximately two
hours for a discharged battery. The charging indicator turns off after the
completion of charging. When any fault condition occurs, the charging
indicator LED blinks at 1 Hz.
Connecting the Sensor
For flicker analyzing the VPL light flicker, probe has to be plugged into the
Sensor connector ➌. The measuring probe can also be connected to ZadPad via
the 80 cm long connecting cable. The connected probe is shown in the Header
info screen ➎

The Header info screen ➎ shows the status information. Clicking the Menu opens
the menu functions.

Measurement
Preparation for measurement
Connect the VLP light flicker probe to the sensor connector. The influences of
other light sources should be avoided if a single lamp is measured. Avoid any
movement or vibration of the sensor during the measurement, especially if a
180-second PstLM measurement is in progress. It is strongly recommended to
mount the probe on a holder or tripod.
Proceeding flicker measurement
First, select the required sample time for the measurement with the Mode
button quick menu:
- 1 sec for standard measurement
- 2 sec for ASSIST Mp measurement
- 180 sec for PstLM measurement
Press the Run button to start measurement.
When the measurement is finished the Measurement windows ➐ open or refresh.
The illumination level should be between 1000 lx and 10000 lx. So the
Recording level indicator must be checked. For accurate results, the level
should be in the green range. The Measurement windows show the light and
flicker values. With the Page switch buttons << >> the different windows
Values, Time graph, and Frequency graph can be selected.
