WARNING
Use the Instrument Only for Its Intended Purpose
The GS200 is a generator that can generate DC voltage and current. Do not use
this instrument for anything other than as a DC voltage and current generator.
Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
Use the Correct Power Supply
Before connecting the power cord, ensure that the source voltage matches the
rated supply voltage of the instrument and that it is within the maximum rated
voltage of the provided power cord.
Use the Correct Power Cord and Plug
To prevent the possibility of electric shock or fire, be sure to use the power cord
supplied by YOKOGAWA. The main power plug must be plugged into an outlet with
a protective earth terminal. Do not disable this protection by using an extension
cord without protective earth grounding. Additionally, do not use the power cord
supplied with this instrument with another instrument.

Safety Precautions
Do not use the power cord in a bundled condition. If you use a power plug with
foreign substance on it, insulation may be compromised by humidity or other
factors and may cause a fire. Clean the power plug regularly.
Connect the Protective Grounding Terminal
Be sure to connect the protective earth to prevent electric shock before turning ON
the power. The power cord that comes with the instrument is a three-prong type
power cord. Connect the power cord to a properly grounded three-prong outlet.
Do Not Impair the Protective Grounding
Never cut off the internal or external protective earth wire or disconnect the wiring
of the protective earth terminal. Doing so poses a potential shock hazard.

Measurement Sample Indicator (On models with the /MON option)
During measurement, an asterisk illuminates. When the measurement completes, the
asterisk turns off. If you are performing sequential measurements that have a short
integration time, the asterisk illuminates and turns off once every 100 ms.
Measured Value (On models with the /MON option)
When the source function is set to voltage, this displays the measured current. When the
source function is set to current, this displays the measured voltage. When there is no
measured value, “-------” is displayed. When the source range is set to 10 mV or 100 mV,
you cannot use the measurement (monitoring) feature. In these situations, the message
“Cannot measure in mV source range” is displayed. When the measurement feature is
turned off, “Off” is displayed.
On models without the monitoring (/MON) option, nothing is displayed in the measured
value area.

Limits
When the source function is set to voltage, this displays the current limit. When the
source function is set to current, this displays the voltage limit. When the source range
is set to 10 mV or 100 mV, the limit is fixed to 200 mA (you cannot change this value). In
these situations, “------mA” is displayed for the limit.
Note
In voltage source mode’s 10 mV and 100 mV ranges, the output resistance is approximately 2
Ω. Therefore, these ranges are not suitable when the GS200 is connected to a load that allows
current to flow (a low-impedance load). Connect a load that allows as little current to flow as
possible (a high-impedance load).
Limiter Indicators
• is displayed when the high limiter is activated.
• is displayed when the low limiter is activated.
Program Execution Status
When a program is running, the following items are displayed.
•Steps: The step number that is currently being executed.
• Time: The remaining interval time (minutes:seconds.tenths of seconds).
Source Range
The source range that is currently in use is displayed here.
