S9901 Mini Dual Channel
Signal Level Meter

Key functions:
Full digital TV/CATV/FM signal
level measurement, Dual-
channel frequency level measurement, inclination ratio
measurement, C/N, V/A measurement, voltage measurement
of trunk alternating current, accompanying sound monitoring
and backlight LCD.

Features:

• More convenient and more practical dual-frequency-
  level measurement.
• Backlight LCD displays large characters under wide
  temperature range.
• Particularity: 0-9 numeric keys enable quickly entering
  measured channels.
• Independent function keys enable quickly accessing
  various measurement states.
• More than 6 hours of operating time with high
  performance Ni-MH batteries.
• Energy saving design, automatically turn off without
  operations over 5 minutes.
• User can change the input end by him/herself.
• More compact, more light.
• High-intensity and anti-shock materials make it a hard
  and durable product.
