Remove the Batteries during Extended Non-Use
Remove the batteries from the main unit.
When Carrying the Instrument
First, turn off the device under measurement. Next, turn off the instrument.
When USB power supply is in use, remove the USB cable. Then, remove all the
cables.
Attaching the Shoulder Strap
Attach the shoulder belt to prevent dropping the instrument. For instructions on
how to attach the shoulder strap, see page 25.
When Cleaning the Instrument
When cleaning the case or the operation panel, gently wipe the outer surface
using a damp, well-wrung, soft, clean cloth. The instrument can malfunction if
water enters inside the instrument.
Do not use chemicals such as benzene or thinner. These can cause discoloring
and deformation.
Other Precautions
• Keep electrically charged objects away from the input terminals. They may
damage the internal circuitry.
• Do not cover the case or operation panel with a volatile material or leave
rubber or vinyl products in contact with the case or operation panel for a long
time.
Notes on generating accurate source
In a small output range, the error in the source value may become large due to
changes in the temperature of the output terminals caused by (1) the conductor
making contact when wiring, (2) changes in the temperature inside the instrument
due to 4-20mA simulation or loop power, or (3) the movement of the surrounding air.
In such situations, wait until the output stabilizes.
In addition, while the instrument is generating output, be careful to keep the output
terminal temperature from changing due to the effects air conditioning, other heat
sources, and the like.
Storage Precautions
Avoid the following kinds of places for storing the instrument:
• Where the temperature falls outside the storage temperature and humidity ranges
• In direct sunlight or near heat sources
• Where an excessive amount of soot, steam, dust, or corrosive gas is present
• Where the level of mechanical vibration is high
• On an unstable surface
• Where an excessive amount of soot, dust, salt, or iron is present
