Operating Precautions

Handling the Cords

 WARNING

If the insulation on a cord melts, the metal conductor may be exposed. Do not use 

any cord whose metal conductor is exposed. Doing so could result in an electric 

shock, burn, or other hazards.

 CAUTION

To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it 

from the outlet or device.

To prevent cord damage, do not step on cords or pinch them between other objects. Do 

not bend or pull on cables at their base.

IMPORTANT

Use only the specified connection cords. Use of any cable not specified by our company may 

result in incorrect measurements due to poor connection or other reasons.

To ensure accurate measurements

 

Warm up the device an hour or more before use.

 

The device should be calibrated once a year.

Transporting Precautions

 

To ensure safe handling, when transporting the device, please use the original box and packing 

materials, but do not use if the box is damaged or warped, or if the packing materials are in poor 

condition or incomplete.

 

When packing the device, make sure to disconnect power supply cords from the main device.

 

When transporting, avoid dropping or other excessive impacts.
