Precautions
1. Handling batteries (for battery-operated model (quartz type) only)
・
At loading batteries, use two C size batteries and confirm that the polarities
(+/−) are correct.
・
Replace the batteries to new ones every year. Be sure to replace all two
batteries with new ones of the same type.
・
Do not get the batteries charged.
・
Do not dispose of used batteries in a fire.
・
For environmental protection, dispose of used batteries in compliance with local
rules and regulations.
NB : When the liquid leaks, immediately wipe or wash out the liguid.
2. Replacement of cartridge pen
・
Pull pen lifting lever toward you until it stops.
・
To remove the cartridge pen, pull toward the direction of the arrow.
・
To attach the pen, slide it onto the pen arm until it stops.
・
Don’t touch pen tip. If the finger grease adhere, ink
will not flow smoothly.
・
Cartridge pen will last about six months (in use of 7
day chart), but life may be shortened by the
conditions of use.
NB : Be sure to use our dedicated cartridge pens.
3. Attaching chart
Make sure the markings on the chart are aligned where the overlap occurs, and
the lower edge of the chart is against the bottom lip of the cylinder.
NB : Be sure to use our dedicated charts.
4. Carrying instrument
Before lifting the instrument with the handle, make sure that it is locked.
●
Installation place
Do not use in the followings. Use in such environments may causes of error in
indication and record.
・
In a place with vibration, shock or inclination.
・
Outdoor use (exception in a instrument screen)
・
At exhaust port of airconditioner or at a place subject to direct sunlight.
・
In dusty of sooty environments.
・
Use of blocking the ventholes of the acrylic cover.
・
Near splashing water.
・
In corrosive gases.
●
Other precautions
・
Use the instrument within the measuring range.
・
Be sure to remove the packing materials that hold the mechanical parts
attached at shipment.
・
Do not cover the instrument with a vinyl or like for waterproof purpose or etc. If
so, correct value will not be obtained.
・
Don’t disassemble the instrument. Doing so may result in failure.
・
Remove the batteries during transportation.

Indication adjustment
Fine adjustment is available, however please avoid using except when necessary
as the instrument is calibrated at our factory. If some adjustment is required,
follow these procedures:
To increase indicated readings, turn the fine adjustment screw counterclockwise.
To lower the indicated readings, turn the fine adjustment screw clockwise. (Figs A-
