1.2. SP-395 Features

The Pyxis SP-395 analyzer is an ultraviolet fluorometer. It measures Halogenated tolytriazoles (HST) in a

water sample. Main features include:

•Sample acidification is not required. HST measurement is independent of sample pH in the

range of 6 to 10.

•Extra color and turbidity parameters measured are used for automatic compensation to

eliminate interference.

•No sample cuvette is needed and variations associated with the cuvette is eliminated.

•Large color graphic screen that can be read in direct sunlight.

•A single conductivity calibration using a single standard covers the whole measurement range of

0 to 15000 µS/cm.

1.3. Unpacking the Instruments

Remove the instrument and accessories from the shipping container and inspect each item for any

damage that may have occurred during shipping. Verify that all items listed on the packing slip are

included. If any items are missing or damaged, please contact Pyxis Customer Service at

service@pyxis-lab.com.

2. Starting SP-395

2.1. Battery Installation

The SP-395 is powered by a 9-volt alkaline battery. Do not use rechargeable nickel cadmium (NiCad) or

lithium batteries. A typical 9V battery lasts for two months and enables about 3000 measurements.

When the battery capacity is critically low, the SP-395 will display a LOW BATTERY warning for 5

seconds and then automatically turn off.

Replace the battery to resume operation of the SP-395 after the battery warning. The SP-395 will

automatically turn on in the measurement mode after new battery installation.

The SP-395 battery compartment, shown in Figure 2, is on the back side of the instrument.

Install battery as follows:

1. Remove the battery compartment cover by loosening two screws.

2. Make sure that the smaller circular terminal (positive) of the battery is aligned with the

hexagonal socket (positive) of the battery holder and the hexagonal socket (negative) of the

battery with the circular terminal of the holder. Snap the battery firmly into the battery holder.

3. Replace the battery compartment cover, making sure that the sealing O-ring is lying flat on the

battery holder. To prevent the SP-395 from accidently being turned on due to vibration, please

firmly tighten the two screws.

2.2. Description of Control Keys

The SP-395 has three keys as shown in Figure 1. The left (<), right (>) and OK keys are used to launch an

action indicated on the screen directly above the keys. Please note that the screen is not a tough screen.

The labels above the keys indicate the function associated with the keys and can change according to

the screen modes.

Figure 3 Key and Functions

2.3. Turning On/Off SP-395

To turn on the SP-395, press OK momentarily and release.

To turn off the SP-395, press and hold the OK key. Release the OK key when the LCD display turns off

(after about 3 seconds). The SP-395 will turn itself off after 60 seconds without user interaction through

the keys.

3. HST Measurement

3.1. Measurement

When powered on, the SP-395 will be in the measurement (read) mode (see figure 3). The displayed

value is the concentration of HST.

The light shield should be in the closed position in order to measure HST. If only conductivity is

measured, the light shield can be left in the open position.

The SP-395 does not need to be turned off between measurements of two samples. Rinsing the

measurement cell several times using the 3mL Transfer Pipet to inject sample is recommended.

Note: Make sure that there are no air bubbles in the sample cup while taking readings. It is

recommended to use the 3mL Transfer Pipet to out the rest of the sample from the

sampling cup.

3.2. High Color and Turbidity Warning

The SP-395 has extra channels to measure sample turbidity and color to automatically compensate

sample color and turbidity interference. If sample turbidity and color values determined are too high, a

warning will be displayed. In such a case, the user should filter the sample for HST measurement.

4. Calibration

Calibration SP-395 requires deionized water and a standard solution. HST calibration uses the 1 ppm or

2 ppm HST standard solution.

To calibrate HST, first select the HST measurement mode. Press the Calib key (<) to start the calibration

procedure. Rinse the sample cell with deionized water three times. Fill the cell with deionized water,

close the light shield, and then press ZERO (<) to finish the zero calibration step. If the zero calibration is

successful, a check mark will be displayed next to Press Zero Button. If any abnormal signal is detected,

an error message will be shown.

Rinse the sample cell with the 1 ppm HST standard. Fill the sample cell with the 1 ppm standard, close

the light shield, and press Slope to finish the slope calibration step. If the zero calibration is successful, a

check mark will be displayed next to Press Zero Button. If any abnormal signal is detected, an error

message will be shown.
