1.0 INTRODUCTION

N N O O T T E E : : Please read these instructions carefully before attempting
to use the instrument.
This Instruction Manual is designed specifically for the LEICA
ABBE MARK II Refractometer and describes proper set up, use
and routine maintenance of the instrument. S S e e c c t t i i o o n n s s 7 7 . . 0 0 - - 7 7 . . 4 4 a a r r e e

The LEICA ABBE MARK II Refractometer is a durable bench-top
instrument. It provides efficient, reliable and repeatable readings
in three modes:
• % Solids ( O Brix)
• % Solids ( Brix) temperature compensated or (BX-TC) and
O
• Refractive index (n D )
The LEICA ABBE MARK II Plus Refractometer can accommodate
a custom program on the % Solids (
complished with pre-programming or retrofitting at the factory.

2.0 UNPACKING

The LEICA ABBE MARK II Refractometer has been carefully pack-
aged for shipping. Before setting aside the packing materials,
check the box(es) to assure that all items ordered have been
received. Among the accessories in the refractometer box will be:
• a refractive index test glass (Catalog No. 10451)
• a 1/16" ( No. 4) Allen wrench (Catalog No. X30600)
• a bottle of 1- Bromonaphthaline for measuring solids
(Catalog No. 10452)
• a dust cover (Catalog No. 10450-140)
Check the instrument and model number against the original
order before discarding any packing materials. The original
packing materials may be saved for future storage or transporta-
tion of the refractometer.

4.0 SET UP

The LEICA ABBE MARK II Refractometer is easy to use.
Very little training is needed to set up and operate the instrument
to obtain temperature and refractive index measurements.

4.1 Equipment Installation

The LEICA ABBE MARK II Retractometer must be used on a hard,
stable and level surface such as a laboratory table or work
bench.
CA A UTION: As a safety precaution, the power cord
has been grounded to the instrument base. Never use a
!
2-prong adapter between the power cord and the power
source; it will render the grounding feature ineffective.
CA A UTION: Use of this equipment other than in the man-
ner specified in this manual may result in reduction of
safety protection.

5.0 CONTROLS

THE LEICA ABBE MARK II Refractometer controls are identified
in Figure 1.
N N O O T T E E : : The mode selector switch no longer functions as the
on/off switch. The ON/OFF switch is located on the lower left
front cover of the instrument above the Leica logo.
P P o o w w e e r r S S w w i i t t c c h h : :
The Power Switch is located in the lower right corner of the front
panel (Figure 1). | = on 0 = off
