Introduction - GRAPHTEC GL2000 User Manual

Thank you for purchasing the GL2000 midi LOGGER HV.
Please read this manual thoroughly before attempting to use your new product to ensure that you use it correctly
and to its full potential.
Notes on Use
Be sure to read all of the following notes before attempting to use the GL2000 midi LOGGER HV.
1. Note on the CE Marking
The GL2000 midi LOGGER HV complies with the following standards.
• EN 61326-1 standard is based on the EMC Directive
• EN 61010-1 standard is based on the Low Voltage Directive (LVD)
Although the GL2000 complies with the above-mentioned standards, be sure to use it correctly in accordance
with the instructions and notes provided in this manual.
Moreover, use of the GL2000 by incorrect procedures may result in damage to the GL2000 or may invalidate
use.
2. Warning
This is a Class A product according to the EMC directive. In a domestic environment, this product may cause
radio interference or may be affected by radio interference to the extent that proper measurement cannot be
performed.
3. Notes for Safe Operation
(1) Be sure to use the Graphtec-supplied AC adapter. In environments where there is a lot of noise or where
the power supply is unstable, we recommend that you ground the GL2000.
(2) When a high-voltage signal cable has been connected to the main unit's analog signal input terminal,
avoid touching the leads of the input terminal's signal cable to prevent electrical shock due to high voltage.
(3) Ensure that the GL2000 power source is positioned so that it can easily be disconnected.
consider a noise and change in measurement voltage.
• Please take care of static electricity when connecting an input cable or a thermocouple.
• Do not touch the tip of thermocouples with bare hand after the thermocouples are connected to the
terminal of this device if the tip of thermocouples is not insulated.
The static electricity from a human body will cause damage to the device.
• Do not put the tip of thermocouples to an object which contains static electricity if the tip of thermocouples
is not insulated. The static electricity of object will cause damage to this device.
• Do not put the tip of thermocouples to an object which contains leaked high voltage of chassis or metal
etc. if the tip of thermocouples is not insulated.
The leaked high voltage from object will cause damage to the device.
• We recommend that the insulation tape puts on the tip of thermocouples before connecting the
thermocouples to the input terminals.
This will protect this device from the static electricity and the leaked high voltage.
