1 Additional information to the operating instructions
1.1 Safety precautions
 Please read this users guide carefully before using the device! Trouble-free
functioning of the device as well as the operational safety can only be guar-
anteed when the safety precautions and the general safety measures de-
scribed in this users guide are considered.
 The device should only be used for its intended purpose and according to
its technical specifications. Any other use of the device is not allowed.
 Immediately after unpacking and before the device start-up, the device
should be inspected for any mechanical damages or loose parts. In such
cases, the device should not be used.
 Safety can also be impaired if the device is not functioning properly.
 If during operation it is suspected that the safety has been impaired, the
device should be switched off and its use by third parties ruled out.
1.2 Hazard clause
 The device described in this instruction manual is designed for optical radi-
ation measurements. The device offers no protection against radiation risks
affiliated with the measured objects.
 Persons in charge of performing measurements and using the device are
obligated to read and comply with the instructions given in this users guide
before beginning any measurement.
 Persons in charge of performing measurements and using the device must
be well informed about accident prevention regulations in their field of work.
 Handling the device requires intermittent concentration of the operator on
the device. The device should therefore not be used in surroundings that
might lead to interrupted operator attentiveness. This possible risk must
also be included in the briefing of the device operator.
 Through this users guide, Gigahertz-Optik GmbH as the device manufac-
turer informs the device owner about the possible hazards while using the
device. The owner and the responsible device users confirm the receipt
and approval of this users guide. The owner and operator of the device
have been informed about the diligence required when choosing and brief-
ing the device users and operators.
1.3 Liability
 The responsibility for all consequences that might arise from the use of the
measurement device or its accessories lies solely on the user and/or own-
er.

Page 5
 Gigahertz-Optik GmbH or its suppliers can under no circumstances be lia-
ble for any direct or indirect business interruptions, loss of profits or data
loss. This also applies to damages that may arise during the device opera-
tion.
 The Gigahertz-Optik GmbH Terms and Conditions of Delivery and Pay-
ment generally apply.
1.4 Safety
 The measurement device is designed for operation in a clean environment
and within operating temperatures ranging from +5 to +40 ºC.
 The measurement device or its accessories are not to be exposed to direct
sunlight or moisture.
 The device should be switched off and secured against unintended start-up
by third parties in case of indications suggesting unsafe operating condi-
tions. Such indicators include:
 when the device shows visible damages
 when the device contains lose parts, either internal or external
 when the device is not functional
 Safe operation of the device can be impaired due to one of the following
circumstances:
 Outdoor storage or storage in moist environment over a long period of
time or other adverse conditions.
 Excessive strain during transport (e.g., due to improper packaging)
 Operation in aggravated environmental conditions such as high temper-
atures, humidity, etc.
 Operation in dangerous conditions (explosive gas, fumes, dust, etc.)
1.5 Environmental conditions
 Optical measurement devices are sensitive to influences resulting from
certain environmental conditions, e.g., high temperatures, humidity, and
contamination, which might lead to measurement errors!
 The measurement device should not be taken from a cold environment and
directly put to operation in a warm surrounding. Under certain circumstanc-
es, condensation could arise and negatively impact on the electrical and
optical functions. Allow the device to adjust to the temperature of the sur-
roundings before switching it on.
 The measurement device should not be operated within high magnetic,
electromagnetic or electrostatic fields.

Page 6
1.6 Maintenance and cleaning
 The intervals for the recurrent recalibrations should be observed!
 Opening of the device as well as device repair should only be done by au-
thorized persons.
 Off-the-shelf, residue-free, and non-abrasive detergents can be used for
the exterior cleaning of the device.
 While cleaning it should be made sure that the detergent doesn’t penetrate
the interior of the device. This can lead to short circuiting or device opera-
tion errors.
 Do not use aggressive cleaning agents.
1.7 Guarantee
 Gigahertz-Optik GmbH warrants that the product is free from material and
production defects for a period of 12 months beginning from the date of
delivery. In case defects are experienced within the warranty period, Giga-
hertz-Optik GmbH repairs or replaces the device free of charge.
 In order for the warranty to be effective, the customer should submit the
product name, serial number, date of purchase as well as the description of
the defect in writing to Gigahertz-Optik GmbH after which he/she will re-
ceive a service number (RMA) enabling him/her to send back the device.
 The user is responsible for the appropriate packaging of the device.
 Shipping through the user must be done on a free to buyer’s address basis.
 The guarantee does not cover consequential damages.
 The Gigahertz-Optik GmbH Terms and Conditions of Delivery and Pay-
ment generally apply.

2 Device description P - 9710 optometer
2.1 Intended use
 The P - 9710 optometers are measurement and examination devices for
optical radiation detectors.
 The device can be controlled manually via front panel buttons or via a
RS232 remote interface.
 Measurement results are displayed on the integrated display (LCD) or
transmitted via the RS232 remote interface.
 Different optical quantities or wavelength bands can be measured by using
different detector heads in combination with the P - 9710 devices.
 The calibration of the optical quantities is stored in the connector plug of
the detector head. This allows using different detector heads with the P -
9710 device or using the detector heads with different P - 9710 devices
without the need to change or transfer calibration factors manually.
 The P - 9710 devices have built-in batteries that are charged with the sup-
plied plug-in power supply. The capacity of the battery allows 5 hours of
operation with display illumination on and 12 hours with illumination off.
2.2 Inspection
 Upon receiving your device, please check the package and all its parts for
any possible damages that may have occurred during transportation.
 Any transport damages should immediately be reported to the shipper.
 After unpacking, please check to confirm there are no transport damages
or any irregularities with regards to package completeness and correct-
ness. The scope of delivery contains:
 one measurement device P - 9710
 one power supply
 a factory calibration certificate
 this users guide
 one hard-top casing (optional)
 one serial interface cable (optional)
 different measurement heads and their calibration certificate (optional)

„CW“ displays the average measurement value for the pre-set integration time
(upper row). The lower row displays the selected wavelength or name of the
connected detector.
„CW Maximum“ displays the max. CW value input signal. Reset with <reset/
esc> key.
„CW Minimum“ displays the min. CW value input signal. Reset with <reset/
esc> key.
CW Maximum and CW Minimum should not be confused with Peak Values.
Peak Values will be calculated for each integration period (integration time) out
of the single ADC samples. CW Maximum and CW Minimum stores the largest
or smallest CW value since the last <reset> key press.
„Peak Maximum“ displays the max. ADC sample value of the integration peri-
od. It will be calculated new for each integration period (see menu "setup" /
"integration time").
„Peak Minimum“ displays the min. ADC sample value of the integration peri-
od. It will be calculated new for each integration period (see menu "setup" /
"integration time").
„Peak to Peak“ displays the difference of max. and the min. ADC sample val-
ue of the integration period. It will be calculated new for each integration period
