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.
