•
Connect all cables and, in PRO version, the
Magnet Temperature Sensor
, then turn on hardware about 30 minutes before beginning of the test, for temperature stabilization
•
For precise comparative measurement always perform measures to the same initial conditions and environment should be fairly stable with constant temperature or humidity
•
The DUT has to have a temperature similar to test room (introduce DUT inside the room at least 2h before measure). However SpeakerLAB PTA notify differences of the
DUT compared to environment conditions
•
Always put
eSensor
in vertical position
•
Use only DUT without passive crossover
•
Work with PTA Lite version in the same test room of DUT
•
Make sure all signal and power cables from the SpeakerLAB PTA hardware to amplifier are connected
•
Always connect the Signal OUT of SpekerLAB PTA to the signal input of Power Amplifier
•
To reduce ground loop connect power amplifier main power in the same point of SpeakerLAB PTA main power
•
Use power amplifier with 20 Vrms minimum capability, we suggest to use at last double power in comparison to your maximum requirement
•
Make sure DUT is well connected to SpeakerLAB PTA, if oxide is present, or the power connectors are not well fastened to DUT, the reading could be not precise
•
For Web Manager version, to see real time measurement from remote devices, allow port 8000 on firewall. The first time we suggest to test connection without firewall
•
Avoid to plug or unplug USB peripherals and other hardware during SpeakerLAB PTA is working
•
Avoid covering air channels in front and rear side of SpekerLAB PTA
•
Avoid covering with metal parts the wireless antenna on front side of SpekerLAB PTA and USB device plugged into pc
•
Insert SpeakerLAB PTA USB Cable or Wireless Dongle, in the same USB port in which it has been installed, otherwise, if device is not recognized, repeat driver
installation procedure in the new USB port
•
Warning Code 5001, 5003: Hardware is power off or USB port is off line
•
Warning Code 5002: Read error on hardware
•
Warning Code 5004: Hardware limit
•
If SpeakerLAB Power Test Analyzer doesn't power on, and the Streaming Led light is off or in a stalled status, while holding front Push Button, then unplug main power
connector and contact factory sending the Log.txt file in SpeakerLAB\Temp directory.
Safety
Primary power supply connection with protective earth conductor is required. Power supply connection with removed earth contact could cause high voltages at the
enclosure of the device. Do not use adapters that disable ground. To reduce the risks of fire or electric shock do not expose the apparatus to rain or moisture. Make
sure the AC mains voltage is correct and is the same as that printed on the rear of the amplifier. Damage caused by connecting the device to improper AC voltage is
not covered by the warranty. Make sure the power is off before making any input or output connections.
Caution!
Risk of electric shock. Do not open the enclosure of device. Hardware has a switching less circuit. When operating the device, certain parts of the module can carry
hazardous voltage (eg. power supply, amplifier/DUT bus bar). When do not operating the device, if main power supply connector is plugged and the device is off,
only a certain points can carry hazardous power supply voltage, these points are also marked with “Caution!” logo on the upper surface of PCB, however in all
points there is any power consumption. Ignoring these warning can lead to injury and/or cause serious damage.
