Handling of plug
6
Be sure to use the power cable included
with the DR-M2/DR-M4.
If a power cable other than the one included
is used, the rated voltage and polarity of the
power may change, and may cause
smoking or fire.
ۍDo not insert the power plug in an outlet
other than AC100 to 240V.
Inserting the power plug in any other outlet
may result in shortcircuiting the unit,
smoking or fire.
ۍ
Do not use the power cable if damaged or
broken.
If used, fire, electrical shock, or burns may
result.
For a new power cable, contact your ATAGO
distributor.
ۍ
When disconnecting the power cable from
the outlet, make sure to do it by holding the
plug.
If the cable is pulled for disconnection, it may
not only break the cable but also cause fire
and electric shock.
ۍ
When connecting the power cable to a mains
AC outlet, ensure that the ground pin is
connected as well.

WARNING
CAUTION

Handling of plug
7
Do not insert or disconnect the power plug
with wet hands.
ۍ
CAUTION
Connection of circulating constant temperature bath
Pay careful attention to hot circulating
water.
ۍFor connecting a circulating constant
temperature bath with the refractometer,
make sure to use the elicon tube 䢪made of
vinyl chloride䢫.
Moreover, tightly fasten each joint part
between the nozzle and tube with the tie
band.
ۍ
If the tube is damaged, replace it with new
one as immediately as possible.
If the damaged tube is continuously used,
the operator may scald himself with hot
circulating water.
ۍ
WARNING
ۍThe temperature of hot water to be
supplied from a circulating constant
temperature bath to this refractometer is
limited to 50䉝, and the flow rate of the
circulating constant temperature bath
should be 10 L/min. at maximum through a
nozzle of 6mm caliber. Too much discharge
not only increases water pressure but also
may cause disconnection between the
nozzle and tube or may overload the water
channel inside the refractometer.
