Safety Summary
Please take a moment to read these operating instructions thoroughly and completely
before operating this instrument. Pay particular attention to WARNINGS used for
conditions and actions that pose hazard to the user and CAUTIONS used for
conditions and actions that may damage the instrument.
 Always to inspect the instrument and other accessories for any sign of damage or
abnormality before every use.
 Never ground yourself and keep your body isolated from ground.
 Never touch exposed wiring, connections or any live circuit conductors.
 Do not install substitute parts or perform any unauthorized modification to the
instrument.
 Use caution when working above 60V DC or 30V AC rms. Such voltages pose a
shock hazard.
 Remember that line voltage is present on some power input circuit points such as
on-off switches, fuse, power transformers, etc., even when the equipment is turn
off.
 Also, remember that high voltage may appear at unexpected points in defective
equipment.

1-1. Introduction
This reciprocal UNIVERSAL(FREQUENCY) COUNTER series are microprocessor
controlled instrument for frequency measurement at high resolution within a short
period of 7 digit display with one second gate time due to uniquely developed LSI as
well as the expanding/reciprocal system. It covers a frequency range from 0.1Hz to 3.3
GHz (FC-3000: 3.3GHz, FC-7150U, FC-7150: 1.5GHz, FC-7015U,FC-7015: 100MHz)

2. INSTALLATION
2-1. Initial Inspection
This instrument was carefully inspected both mechanically and electrically before
shipment. It should be physically free of damage. To confirm this, the instrument
should be inspected for physical damage in transit. Also, check for supplied
accessories.
2-2. Connecting AC Power
This instrument requires ac 230V 50-60 Hz power through 3-conductor ac power
cable to be fit into three-contact electrical outlet to secure grounding. If forced to use 2-
conductor cable, use ground terminal in rear panel for grounding instrument.
CAUTION
THIS INSTRUMENT IS SET TO AC 230V. BEFORE POWERING ON THIS
INSTRUMENT, MAKE SURE THE VOLTAGE OF THE POWER SOURCE IS AC
230V.
2-3. Cooling and Ventilation
No special cooling and ventilation is required. However, the instrument should be
operated where the ambient temperature is maintained.
2-4. Position
This instrument is built as a bench-type instrument with rubber feet and tilt stand in
place. Stand-up angle can be adjusted by rotating angle of carrying handle.
2-5. Warming-Up
Allow more than 20 minutes for the unit to warm up so that it is stabilized and ready
foruse.

GATE INDICATOR : The gate light, when lit, indicates the main gate is open
and measurement in progress.
DISPLAY : 9 digit(O.56") green LED display used for all read
readings.
NOTE: LAST MEASUREMENT DISPLAY WILL REMAIN FOR 10 SECONDS AFTER
SIGNAL OFF.
UNIT INDICATOR : When lit, indicates that the frequency displayed is in KHz
or MHz, and period is in n, u or mSec.
HOLD INDICATOR : When lit, engaged the hold function.
HOLD SWITCH : In hold function the display held but the counters
continue to increment. When the hold is released, the
display is updated and resumes counting.
RS-232C INDICATOR : TX(transmitting), RX(receiving) blinking(OPTION)
TRIG. LEVEL VR : Adjusts trigger threshold level on the input A input signal.
Pushing the knob in (preset) sets this level at the mid-
point of a symmetrical sinewave input. Pulling the knob
out and rotating it varies the level from negative to
positive around the mid point.
