Failure to comply with the precautions below could lead to injury
or death or damage to the instrument.
WARNING
Use the Instrument Only for Its Intended Purpose
This instrument is equipped with DC current and DC voltage measurement and generation
features as well as a pressure measurement feature. It is a calibrator for pressure devices.
Use the instrument only for measuring and generating DC current and DC voltage, measuring
pressure, and calibrating pressure devices.
Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
Do Not Operate in an Explosive Atmosphere
This instrument is not explosion-proof.
Do not operate the instrument in the presence of flammable gases or vapors. Doing so is
extremely dangerous.
Do Not Remove Covers or Disassemble or Alter the Instrument
Removing covers and disassembling or altering the instrument are strictly prohibited.
Some sections inside the instrument have high voltages that are extremely dangerous. For
internal inspection and adjustment, contact your nearest YOKOGAWA dealer.
Measuring High Pressure Fluid
• Use piping and pressure connectors that can withstand the pressure to be measured.
• Make sure that there are no leaks from the piping, connectors, and joints and that the joints
are not loose. If the fluid under measurement leaks or if a joint comes loose, the pressure
can endanger the user or the surrounding instruments. Note that higher the pressure,
greater the danger.
• Depending on the amount or type of gas, if you are handling gas that is 1 MPa or higher,
safety laws related to high pressure gas may require supervision.
• Do not measure flammable, explosive, poisonous, or corrosive liquids.
Such an act can endanger the user.
Observer the Pressure Limit
Do not apply pressure exceeding the allowable input range. Doing so may cause damage to
the instrument.
Measurement Category
The measurement category of this instrument is Other (O). Do not use it to measure the main
power supply or locations that fall under Measurement Categories II, III, and IV.
Install or Use the Instrument in Appropriate Locations
• The instrument complies with protection level IP54. Do not install the instrument in
locations whose level exceeds this protection level.
• Install the instrument so that you can immediately remove the batteries if an abnormal or
dangerous condition occurs.
CAUTION
• Do not use the instrument to measure gas or liquids that can corrode the piping material,
high temperature liquids (50°C or higher) or gas-liquid mixtures.
If you are measuring gas, make sure the gas is dry and clean. Do not measure air with high
moisture or high oil content.
