Description
NTI MINILYSER
A professional, hand-held, analogue-audio signal-analyser, with built-in microphone, balanced and unbalanced line inputs, 100 x 64 pixel back-lit LCD display and simple, menu, control buttons.
The display-screen shows menu options and measurement values, with either large-scale numerical read-out or graphic display (including frequency-response and oscilloscope). Auto-ranging algorithms provide fast, accurate readings, with a minimum of menu selections for rapid testing and analysis. A 3.5mm headphone jack-socket is also provided, for aural monitoring. Minilyser can be used with the NTI Audio Minirator or other signal sources, such as Canford “Quick Check” test media. Battery-powered (3 x AA dry or NiCd), with over 16 hours continuous use (typical) from alkaline batteries. A carrying pouch is also available.

Calibration
NTI Audio text instrument calibration certificates, where available, are issued by the factory in Liechtenstein, thus avoiding out-of-date certificates being shipped with items held in stock in the UK. Canford also offer NTI Audio instruments without certificates, for those who do not require them, reducing delivery time and cost. Where certificates are available, the instruments are listed twice, with or without certificates. Where instruments can be provided with calibration certificates at a later date, this service is also listed separately. The instrument should be shipped to Canford, where despatch to and return from the factory will be arranged. Please contact Canford Customer Services for an RMA number.
