2.2 Selection of Installation Site

Meet with the customer and decide upon a suitable installation site before commencing installation of the UV-1700. And be sure to install the instrument in a site that conforms to the following parameters to ensure that the instrument will perform appropriately and stably over a long period.

 Room temperature: 15°C to 35°C  Out of direct sunlight  No strong vibration or continuous weak vibration  Away from devices emitting strong magnetic fields, electromagnetic fields or high

frequencies

 Humidity: 45% to 80%  Away from corrosive gases and organic or non-organic gases with absorbency in the

ultraviolet region

 Away from dust  Installation workbench must be able to bear the UV-1700’s weight of 17kg (if a PC

system is to be used, PC and printer weights must be taken into consideration as well)

Note that the dimensions of the UV-1700 are W 550 x D 470 x H 380mm (200mm high when LCD is retracted). Therefore the installation site needs to be at least W 700 x D 500mm. A power switch and cooling fan are mounted on the left side of the main unit. Install the instrument in a location where ventilation will not be hindered.

2-4

2.3 Installation of UV-1700

Once the installation site has been decided, install the UV-1700 in accordance with the following procedures.

2.3.1 Power Check

The UV-1700 uses a 130VA power supply. Be sure to use a power supply of at least 130VA (if a PC system is to be used, PC and printer power supplies must be taken into consideration as well). Also, power supply voltage fluctuation tolerance is low-voltage instrument if voltage fluctuation exceeds

±10%.

±10%. Use a

2.3.2 Grounding

The UV-1700 power cable has three wires including a ground wire. Check to see that the power outlet has a ground terminal. If the power outlet does not have ground terminal, be sure to ground the instrument using the ground terminal of the standard accessory ground adapter (071-60803-01) or the ground terminal on the left side of the instrument.

2.3.3 Instrument Installation and Power Cable Connection

1) Install UV-1700 in location that will not hinder ventilation for cooling fan situated on left side of instrument.

2) Check that the power switch on the main unit is OFF (with O pressed).

3) Check that the voltage setting of the input voltage changeover switch corresponds to the working supply voltage. If differing power voltages are displayed, open the fuse holder using a slotted screwdriver, pull out the round plug and insert it at the location displaying the used power voltage.

4) Check that a 4.0A fuse is used in the 100V system and that a 2.0A fuse is used in the 200V system.

5) Insert the provided power cable to the power connector on the left side of the main unit.

6) Insert the power cable in the power outlet.

2-5

2.4 Instrument Baseline Correction

Once installation is complete, be sure to carry out instrument baseline correction following the steps below.

1) Turn ON the power switch of the UV-1700. After checking that initialization has ended correctly, energize the instrument for at least 30 minutes to stabilize it.

2) Press the [F3] key Mainte. on the Mode selection screen to display the screen on the left.

3) Press the [2] key to execute instrument baseline correction.

4) Instrument baseline correction requires approximately 15 minutes. Once correction is complete, correction date and time will be displayed in the column where previous correction date and time were located.

Activating the instrument while holding down the [F1] key sets the instrument validation measuring parameters and pass criteria values to the default settings, which are different to the normal parameters.

3.1.2 Checking of Baseline Stability

To implement baseline stability inspection, the instrument power supply must be turned ON for at least one hour prior to inspection. A warning message will be displayed if one hour has not elapsed from when the power was turned ON.

3.1.3 Checking of Baseline Flatness

To implement baseline flatness inspection, the instrument power supply must be turned ON for at least one hour prior to inspection. A warning message will be displayed if one hour has not elapsed from when the power was turned ON.

3.2 How to Use Instrument Validation

Use the instrument validation functions installed in the UV-1700 to check basic performance. This item explains how these functions are used.

3.2.1 How to Enter Instrument Validation Mode

1) Press [F3] key Mainte. at the mode selection screen to display the Maintenance screen. Next, select “1. Validation” to display the validation screen.

2) The check item selected for implementation is highlighted. For example, wavelength accuracy (WL Accuracy) is highlighted for implementation in figure 3-1.

3) Press the [START] key to execute inspection of the highlighted item.

4) There are two types of check available: “Semi-Auto items” and “Auto items”. Semi-automatic inspection is divided into items that require manual tasks such as filter changing. Automatic inspection is divided into items that the instrument automatically checks without any need for manual tasks.

Press the [3] key to enable input of pass criteria value. Input range is 1 to 99. Input the “2” value.

 Recommended Value

The pass criteria value can be set to a recommended value. Do not use this item at this point.

3) Press the [RETURN] key twice to return to the instrument validation screen. Now press the [START] key to implement inspection followed by printout of results.

4) Check that baseline flatness is within shock noise is within 4mAbs.

3.9 Noise Level

This measures for one minute the time variation in the vicinity of zero absorption (0Abs) for the specified wavelength, and checks the P-P noise from that amplitude. It also calculates the RMS value from the one-minute data.

Specification: P-P Within 2mAbs (same for each wavelength)

RMS 0.2mAbs or less (@700nm)

0.3mAbs or less (@500nm)

0.4mAbs or less (@250nm)

[Checking Method]

1) Press the [6] key at the auto items screen to display the noise level parameter settings screen.

2) Set the parameters to match those shown in figure 3-12.

 Inspection

Each press of the [1] key selects (Yes) or deselects (No) the inspection. Set inspection to the "Yes” item.

 Check λ

Press the [2] key to enable input of wavelength to be measured for time variation. Input “700.0”.

 Tolerance

Press the [3] key to enable input of pass criteria value. Input range is 0.0 to 99.9. Input “2” as the P-P value and “0.2” as the RMS value.

3.10 Photometric Accuracy

This measures the optic filter for transmittance correction, checks the deviation against the validation value and makes the result the photometric accuracy. Check photometric accuracy using the semi-automatic inspection item in the instrument validation functions.

Specification: Within Within Jig: NIST substandard filter (P/N 755-03576) CPS-240A (P/N 204-05837-01)

[Pre-inspection Preparation]

Bring the NIST substandard filter to a constant temperature.

1) Turn ON the power for the CPS-240A. Set temperature to 23.5°C.

2) Set the NIST substandard filter in the cell holder of the CPS-240A. Maintain the filter at a constant temperature.

Cell position 1: None Cell position 2: 10%T (vicinity of 1Abs) filter Cell position 3: 30%T (vicinity of 0.5Abs) filter

Note

The NIST substandard filter must be maintained at 23.5°C during inspection because the measuring value varies with the temperature of the filter.

±0.002Abs (vicinity of 0.5Abs)

±0.004Abs (vicinity of 1.0Abs)

[Checking Method]

1) Press the [1] key at the semi-auto items screen to display the photometric accuracy parameter settings screen.

2) Set the parameters using those shown in figure 3-13 as reference.
