P. 2 / 8
• Do not store or use the unit in environments subject to
chemical evaporation (such as that of organic solvents), or
where there are chemicals and/or acids present in the air.
• Do not use paint thinner or organic solvents to clean the
unit.
•
Observe the environmental conditions when using the unit.
• Wait at least for 15 seconds before turning on the power
supply after it has been turned off.
■
ENVIRONMENT
• Indoor use
• The unit is designed to be mounted on a vertical panel. It
is not suitable for a slanted or a horizontal panel surface.
• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■
GROUNDING
• Be sure to determine in advance the most stable ground
-
ing point in the environment and earth the unit’s FE ter-
minal and that of connected devices to it in order to pro-
tect the devices from dielectric breakdown.
• Grounding is also effective to eliminate noise that could
cause errors in the unit’s operation.
■
MEMORY CARD
• Do not turn off the power supply to the unit or reset it dur
-
ing recording. The memory card may be destroyed.
• Observe the described procedure when you need to replace
the memory card during recording.
• Confirm the sides and the connector position of the mem
-
ory card when inserting one to the card slot.
• Do not touch the metal terminal with your hands or me
-
tallic tools.
• Memory cards have a life span. Back up your important
data.
■
LCD PANEL
• The LCD panel’s liquid contains an irritant. If the panel
is damaged and the liquid contacts your skin, rinse imme-
diately the contact area with running water for at least 15
minutes. If the liquid gets in your eyes, rinse immediately
your eyes with running water for at least 15 minutes and
consult a doctor.
• The following phenomena are LCD characteristics, and
NOT a product defect:
- LCD screen may show uneven brightness depending
upon displayed images.
- The LCD screen pixels may contain minute black-and-
white-colored spots.
-
The color displayed on the LCD screen may appear differ-
ent when seen from outside the specified viewing angle.
- When the same image is displayed on the screen for a
long time period, an afterimage may appear when the im-
age is changed. If this happens, turn off the unit and wait
15 seconds before restarting it.
• To prevent an afterimage plan to change the screen image
periodically so that the same image does not remain for
the long time period.
■
MINIMIZING NOISE INTERFERENCE TO ANALOG SIGNAL CABLES
• Noise entering through the analog signal cables may
cause irregular measurement values, degradation of over-
all accuracy, and malfunction of the product. We recom-
mend that you would conduct wiring to the unit with the
following points of caution.
• Do not install cables (power supply, input and output)
close to noise sources (high frequency line, etc.).
• Do not bind the analog I/O cables together with those in
which noises are present. Do not install them in the same
duct.
■
DO NOT APPLY OVERRANGE INPUT
• Do not apply voltages exceeding ±15V to terminals V
– COM and AB – C to prevent damage. Do not apply cur-
rents exceeding ±30mA to terminals I – COM to prevent
damage.
■
INTERNAL CLOCK
• The internal clock data is stored in memory powered by a
backup battery while the unit is without external power
supply.
• The data will be reset to its default status when the bat
-
tery is used up while the unit is left without power supply
for a long time period. The clock adjustment will be neces-
sary once the power is restored.
• Once the power is restored, the unit starts recharging the
battery. It will be full in approximately in 36 to 48 hours.
• Battery backup: approx. one month
■
AND ....
• We recommend use of an UPS to supply power backups.
• The unit is designed to function as soon as power is sup
-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.
