(Measurement categories) EN 61010-1:2001 specifies the measurement categories and their requirements as follows. The
GOS-630FC falls under category II.
• Measurement category IV is for measurements performed at the source of low-voltage installations.
• Measurement category III is for measurements performed in building installations.
• Measurement category II is for measurements performed on the circuits directly connected to low voltage installations.
• Measurement category I is for measurements performed on circuits not directly connected to mains.
Power Supply
•
AC Input voltage: 115V/230V AC, 50/60Hz
WARNING
•
The power supply voltage should not fluctuate more than 15%.
•
To avoid electric shock, connect the protective grounding conductor of the AC power cord to
•
Fuse type: T0.63A/250V (AC 115V),
T0.315A/250V (AC230V)
•
•
•
• an earth ground.
Make sure the correct type of fuse is installed before power up.
To ensure fire protection, replace the fuse only with the specified type and rating.
Disconnect the power cord before fuse replacement.
Make sure the cause of fuse blowout is fixed before replacing the fuse.
Cleaning the instrument
•
Disconnect the power cord before cleaning the instrument.
•
Use a soft cloth dampened in a solution of mild detergent and water. Do not spray any liquid into the instrument.
•
Do not use chemicals containing harsh products such as benzene, toluene, xylene, and acetone.
Operation
Environment
Storage environment

Location: Indoor, no direct sunlight, dust free, almost non‐conductive pollution (See note below)
•
Relative Humidity: < 85%, non‐condensing

(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements as follows. The GOS-630FC falls under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”.
• Pollution degree 1: No pollution or only dry, non-conductive pollution occurs. The pollution has no influence.
• Pollution degree 2: Normally only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.
• Pollution degree 3: Conductive pollution occurs, or dry, nonconductive pollution occurs which becomes conductive due to condensation which is expected. In such conditions, equipment is normally protected against exposure to direct sunlight, precipitation, and full wind pressure, but neither temperature nor humidity is controlled.

Power cord for the United Kingdom
When using the instrument in the United Kingdom, make sure the power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the following code:
Green/ Yellow: Earth
Blue: Neutral
(Phase)
As the colours of the wires in mains leads may not correspond with the colours marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with the letter E or by the earth symbol or coloured Green or Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact the supplier.
This cable/appliance should be protected by a suitably rated and approved
HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, cable of 0.75mm
2
should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used.
Any moulded mains connector that requires removal /replacement must be destroyed by removal of any fuse & fuse carrier and disposed of immediately, as a plug with bared wires is hazardous if a engaged in live socket. Any rewiring must be carried out in accordance with the information detailed on this label.

RODUCT OVERVIEW
Product Description
The GOS‐630FC oscilloscope is a portable, dual‐channel oscilloscope.
The GOS‐630FC provides maximum 30MHz DC bandwidth and
1mV/DIV sensitivity. Its time base reaches 0.2μS/DIV and the sweep speed 100nS/DIV. The GOS‐630FC uses a 6‐inch rectangular cathode ray tube display with red internal graticule. This is a sturdy, easy‐to‐ operate, and highly reliabile product. The GOS‐630FC also incorporates a separate LCD Display, which can show CH1/CH2
VOLT/DIV, TIME/DIV, X‐Y MODE, and Frequency.

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
Main Features
High intensity and acceleration
CRT
The CRT incorporates high beam transmission, high intensity, and a 2kV high acceleration voltage.
The CRT displays clearly readable traces even at higher sweep speeds.
Wide bandwidth and sensitivity
In addition to the DC‐30MHz (‐3dB) wide bandwidth, the oscilloscope provides a 1mV/DIV high sensitivity. The 30MHz frequency range is obtained by an improved triggering synchronization.
Frequency
Counter
A built‐in 5‐digit frequency counter offers ±0.02% accuracy between 1kHz and 30MHz, and ±0.05% between 50Hz and 1kHz.
Automatic timebase adjustment
Alternate triggering
Pressing the AUTO TIMEBASE key automatically adjusts the sweep time to an appropriate range.
Even when observing two waveforms in different frequencies, both waveforms can be stably triggered using the alternate triggering mode.
TV sync triggering:
The oscilloscope has a sync separator circuit for the TV‐V and TV‐H signal triggering.
CH1 output
The CH1 signal is output from a rear panel terminal, which can be applied to external devices.
Z-axis input
Display intensity can be controlled via the TTL compatible z‐axis input on the rear panel.
X-Y mode
The X‐Y mode compares the CH1 and CH2 signal amplitude. It is useful for comparing the phase difference.
Buzzer alarm Incorrect operation generates a warning beep.

Frequency Measurement
Frequency shown on the
LCD
The frequency of the input signal appears on the
LCD display and is constantly updated.
X-Y Mode
Background
The X‐Y mode compares the amplitude of two signals (CH1 and CH2), one as X‐axis (CH1) and the other as Y‐axis (CH2). The X‐Y mode is useful for measuring the phase difference of two signals, video color patterns, and frequency response.
Steps
1. Make sure both CH1 and CH2 waveforms appear on the display. For details, see page29.
2. Move the TIME/DIV knob to the
X‐Y position.
3. The CH1 and CH2 signals appear in the X‐Y mode and the X‐Y indicator in the LCD display
( X‐Y ) turns on.
Frequency measurement using the CH1 output
The CH1 signal frequency can be measured using an external device such as frequency counter, via the rear panel terminal.
4. To adjust the X‐axis position and deflection, use the horizontal
POSITION knob (position) and
CH1 VOLTS/DIV knob
(deflection).

FAQ
The input signal does not appear on the display.
Check the following settings.
•
The coupling mode is not set at the GND mode, in which the waveform does not appear on the display. See page22 for details.
•
The appropriate trigger source is selected. See page19 for details.
The oscilloscope accuracy does not match the specifications.
Make sure the oscilloscope is powered on for at least 30 minutes, within +20°C – +30°C. This is necessary to stabilize the oscilloscope.
