NTI AUDIO MINIRATOR MR2

A professional, hand-held, analogue audio signal generator, with balanced and unbalanced outputs and back-lit LCD display. The generator produces sinusoidal signals, swept signals (Sine, Stepped or Continuous Sweep), white and pink noise, and a polarity-test (phase check) signal. The simple controls of rotary selection, common function 'hot-keys', mute key and informative display allow fast and accurate operation in the field or laboratory. Battery (3 x AA dry or NiCd) powered with over 20 hours continuous use (typical) and selectable auto-switch-off function. For continuous operation an external DC power inlet is included. A USB interface enables firmware updates via the NTI Audio website.
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text instrument calibration certificates, where available, are issued by the factory in Liechtenstein, thus avoiding out-of-date certificates being shipped with items held in stock in the UK.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.
