IOLMaster®700 General Information
1.2 About This Manual
1.2.1 General Notes
This manual is the field service reference for troubleshooting, repair, adjustment, and calibration of
the IOLMaster®700. The manual is intended for use by field service engineers who have completed
ZEISS specific service training on the IOLMaster®700.
The service manual is designed to support Level 1 of a two-level service strategy. Level 1 (on-site)
field service employs modular replacement of printed circuit boards and other assemblies that are
most effectively repaired on site. This is the service strategy used in field service, and presented in
ZEISS training classes. Level 2 (workshop repair) include procedures which are not possible on-site or
where on-site repair was not successful. See section 1.4, page 5for additional information regarding
the IOLMaster®700 service strategy.
The procedures in this manual assume that the reader is familiar with operation of the instrument.
Complete operating instructions are contained in the IOLMaster®700 User Manual. Information
presented in the user manual is not repeated in this service manual. The user manual can be ordered
separately as a standard ZEISS part.
Update revisions to this service manual will be issued by Service Bulletin, as required.
The general layout of the service manual is shown below. For greater detail, please refer to the Table

IOLMaster®700 General Information
1.4 IOLMaster®700 Service Strategy
The service strategy for IOLMaster®700 envisages that field service must only be performed by
appropriately trained technicians authorized by ZEISS. These activities are described in this service
manual and are dealt with in detail during the service training for this product.
Only original spare parts must be used.
For maintenance and repair adequate ESD protection measures must be taken. Only tools specified in
the tools list must be used (see section 7).
1.4.1 General Safety Instructions
If you need to gain access to the interior electronics of the IOLMaster®700, especially the computer
base, always disconnect the instrument from any and all power sources first.
For maintenance and repair adequate ESD protection measures must be taken. Only tools specified in
the tools list may be used (see section 7).
Only original spare parts listed in section 7 and the official CZM spare part price list must be used.
Do not use or install software which is not approved and tested by CZM. Other procedures than
described in this manual are not allowed to be performed by the field service engineer.
After any kind of manipulation or changes perform a System Checkout in accordance with the
instrument checklist and initiate a technical safety check according to section 2, especially after the
service of electronic parts directly connected to the main power, e.g. power supply, main switch and
power entry module.
1.4.2 Laser Class
Based on the IEC 60825-1 laser class specification the following laser classes can be found within the
IOLMaster®700.
Class 1
Normal Use with Measurement Head covers in place
Class 1M
Service Activity with Measurement Head covers removed.
WARNING RISK OF OPTICAL RADIATION
Once the Glass Fiber is disconnected, do not look directly or via any optical tool, such
as mirrors, magnification lenses or microscopes into the Laser, in order to prevent
potential damage to the Eye.

2.3 Technical and Electrical Safety Check
2.3.1 General Information
The detailed description of the technical safety check procedure can be found in
Service Manual SM-30-8005-116 (Medical Electrical Equipment in Field Service) This Manual is for all
Carl Zeiss Meditec AG medical products applicable and equates the latest international rules for
electrical safety. Additionally, this service manual also describes the most important procedures
inclusive instrument specific procedures e.g. the reading points for the different tests.
NOTE
If you have national rules for electrical safety, Service Manual SM-30-8005-116 is in force
only analogous. In this case you have to fulfil the values of your national standards (e.g.
NFPA 99, AAMI ES-1).
Only qualified technicians shall perform these tests. Qualification shall include training on the subject,
knowledge, experience, and acquaintance with the relevant technologies and regulations. The
technician shall be able to assess safety and shall be able to recognize possible consequences and
hazards arising from non-conforming equipment.
2.3.2 Procedure of the technical safety check
Complete the following points in line with the test procedures of the Instrument
Checklist:
Check that the housing (in particular the ventilation slots) is undamaged and free from
contamination.
Check all cables (in particular the insulation) for damage.
Check that all notes and labels are complete and correctly positioned using the user manual.
Checking the electrical safety
(This test must be performed as part of the installation procedure, the annual maintenance service
and technical safety check, or after repairs affecting safety-relevant components).
During the technical safety check, the device must be tested for electrical safety.
Perform the measurements in accordance with IEC 62353:2007 and DIN EN 62353:2008.
The measuring results must be documented in the technical safety check report.
Refer Service Manual SM-30-8005-116.

Procedure:
1. Measuring protective ground resistance
A maximum test voltage of 24V and a test current of 10A AC are recommended for measurement.
1) Connect the device with its connecting cable to the power socket of the safety tester
(e.g. RIGEL 288).
2) Firmly press the test probe against a screw head on the housing of the IOLMaster (see Fig. 2)
3) Start the measurement and note down the measured value.
4) If the IOLMaster is powered via the power socket of the IT table, repeat the measurement for the
table. The same applies if the system is operated via a multiple socket. Include the multiple socket
into the measurement in this case.
5) Note down the highest value measured.
Note
The limit value that must not be exceeded is 0.3 Ohms for devices with a power cord
and 0.5 Ohms for systems with a multiple socket.
2. Measuring the leakage current
We recommend using the differential current method, where the device is measured during
operation and both phase directions are taken into account. The IOLMaster connected and operated
via the safety tester.
1) When using the RIGEL 288 tester, select IEC 62353, differential measurement and semi automatic
mode (to boot and shut down the computer manually during reversal of polarity).
2) Please note the risk of a computer damage using safety testers with fully automatic reversal of
polarity!
3) Switch on the instrument at the main switch.
4) Firmly press the test probe against a screw head on the housing of the IOLMaster (see Fig. 1 and
Fig. 2) and start measurement. The tester automatically performs a reversal of polarity.
5) Note down the highest value measured.
Note
The limit value of 0.5 mA must not be exceeded in any of the measurements.
3. Measuring the insulation resistance
Perform this measurement at 500V DC.
1) Connect the power cord of the IOLMaster to the power socket of the safety tester.
2) Switch on the instrument at the main switch.
3) Start the measurement.
4) Note down the measured value.
Note
The measured value must not be less than the limit value of 2 MOhm.
If the IOLMaster is operated via the power socket of the instrument table and/or via a multiple
socket, repeat the measurements accordingly.
