2
Thank you for purchasing the MAVOPAD flicker meter from GOSSEN.
Please read these operating instructions carefully before using the system for the first
time, and keep them in a safe place for future reference.
Your new flicker meter is designed for extremely fast and accurate measured value acquisition
and is equipped with lots of computing power. This makes it possible to conduct extensive
analyses involving time and frequency, which are prerequisites for the ascertainment of currently
relevant measured quantities for flicker.
▪Excellent measuring accuracy –16-bit A-D converter resolution
▪Extremely fast sampling rate –up to 1.6 MHz, as many as 4 measuring channels
▪Various assessment methods –PstLM, SVM, flicker%,flickerindex, modulation, dominant
frequency, ASSIST Mp or IEEE 1789
▪Universal display –display of measured values, time plot and frequency spectrum
▪V(λ) matching –the spectral sensitivity of the VLP sensor is color corrected and
corresponds to the spectral brightness sensitivity of the human eye V(λ).
▪Integrated data memory –data can be stored to and retrieved from internal USB memory.
▪Test certificate –included in the scope of delivery
▪Intuitive operation –4.3" touchscreen display with direct access to important functions

▪In the event of malfunction, switch the meter off immediately. If smoke or odors occur for which the
meter or the mains power pack is the cause, immediately disconnect the power pack from the mains
and switch the meter off –risk of fire and injury.
▪Do not use or charge the meter in proximity to flammable or combustible gases –risk of fire and
explosion.
▪Never charge the meter unattended –risk of fire and injury.
▪Keep the meter and all accessories out of the reach of children –risk of suffocation and strangulation
due to parts which can be swallowed, as well as carrying straps and cables.
▪Do not dismantle, modify or repair the meter –risk of injury, fire and electric shock.
▪Do not expose batteries to moisture, high heat or open fire, and never short circuit batteries or
attempt to open them. Use only batteries which are recommended for this meter and which
demonstrate no apparent damage. Improper handling of batteries can result in fire, explosion,
serious injury or environmental damage.
Warning!

▪In the event of malfunction, switch the meter off immediately. If smoke or odors occur for which the
meter or the mains power pack is the cause, immediately disconnect the power pack from the mains
and switch the meter off –risk of fire and injury.
▪Only use the included charger to charge the meter. The use of other chargers may damage the
meter.
▪When plugging in the sensor and the sensor extension cord, make sure that the plug and socket
guides are correctly aligned and avoid the use of excessive force. An incorrect plug connection can
damage the meter, the sensor or the sensor extension cord.
▪Do not use the meter where it’s exposed to moisture or rain, and do not immerse it in water. Avoid
operation with wet or damp hands as well. This may result in electric shock or damage to the meter.
▪Do not dismantle, modify or repair the meter. This may result in erroneous measurement results or
damage to the meter.

Note
As a signal word, Note identifies precautions or limitations with regard to use of the product. Please
read all notes in order to avoid operating errors.
▪Before starting one-time only measuring tasks, you should convince yourself beforehand that the
meter is working properly by performing a test measurement.
▪If the product is used in quality-relevant applications, for acceptance measurements or for
assessments, check to make sure that the meter’s calibration is still valid.
▪If the meter is subjected to extreme temperature during transport, it requires at least 2 hours for
acclimatization before it’s switched on.

3 Initial Startup
3.1 Charging the Battery
The MAVOPAD is equipped with a built-in lithium-ion battery which can be charged via the USB socket
➋and the included 5 V / 1500 mA mains power pack. First connect the meter’s USB socket to the USB
socket on the mains power pack using the included USB cable, and then plug the mains power pack
into an electric outlet.
The charge level LED ➍on top of the meter indicates the charging status of the rechargeable battery.
It lights up red as long as the battery is charging and goes out when the battery has been fully charged.
If the charge level LED blinks once per second, an error has occurred during charging. If this is the
case, immediately disconnect the meter from the charger. Charging time for a fully depleted battery is
about 3 hours.
If the meter is not used for a lengthy period of time, it should be recharged about once every 6 months.
This ensures long battery life and retention of clock time and device parameters.
3.2 Connecting the Sensor
In order to measure flicker, the VLP light sensor has to be plugged into the sensor socket ➌. The sensor
can also be connected to the MAVOPAD via the sensor extension cord with a length of 80 cm. The
connected sensor is displayed under “Sensor Information” ➂in the information and status display ➎.
