Introduction
Thank you for purchasing the Digital Immersion Refractometer, PAN-1DC. Before operating, read this
instruction manual carefully to understand its contents. Keep the manual with the instrument for future
reference.
Safety Precautions
To use the instrument safely, the precautions described in this instruction manual must be observed.
Failure to comply may result in injury and/or damage to property.
WARNING
Use caution as hot samples can cause severe burns. Do not dip the instrument directly into
a boiling pot to measure.
When measuring hazardous materials, use proper safety procedures, materials, and clothing to avoid personal injury.
Anyone handling hazardous materials should understand their properties and safety requirements.
If the instrument is dropped or subjected to a strong impact, contact your supplier for inspection.
Do not attempt to repair, modify, or disassemble the instrument.
CAUTION
Do not dip the instrument in any sample that is over 100 .
ATAGO is not liable for any loss and damage caused by the measurement and use of this instrument.
If this instrument is used to measure highly acidic samples, the prism and prism head may be damaged, resulting in
inaccurate measurements.
The prism is made of optical glass. Metal tools and/or implements can damage the prism surface. If the surface of the
prism is scratched or damaged, inaccurate measurements will occur.
Before use, carefully read the instruction manual and fully understand the function and operation of the instrument.
Supply the instrument with DC24V only (allowable fluctuation is 10 %).
Do not use power cables that are damaged or modified.
Do not insert or disconnect the power plug with wet hands.
Do not leave the instrument in a location exposed to direct sunlight or near a heat source for any extended period of
time.?
Do not change the ambient temperature of the instrument suddenly.
Do not place the instrument where it will be subject to strong vibrations.
Do not use the instrument where there is an excessive amount of dust.
Do not store the instrument in an extremely cool area.
Do not set or drop heavy objects on the instrument.
Note regarding water resistance
Only the prism head of the instrument should be submerged into water.
ELI Function
The instrument is equipped with the External Light Interference (ELI)
function to ensure accurate readings
If the instrument is subjected to intense light, such as direct sunlight or
artificial lighting, when measuring a sample or zero setting, the ELI
function will display the [nnnn] (Fig.A) warning message immediately after
the START or ZERO key is pressed. When this happens, shade the prism
head and press the START or ZERO key again. If the warning message
continues to be displayed, place the sample in a non-translucent cup to
measure.

6. Installation

Adjust the height of the display unit at the
clamp and fasten the mounting screw to
securely fix the shaft in position.

The clamp mount spins free when the
mounting screw is loosened, allowing for
shaft height adjustment at any desired
angle. Position the display unit upright after
the height adjustment is complete.
