ANALYSIS:
Press the <ON> key and make sure the meter is set for Program “A.” (NOTE: If changing the
program, see “Selecting a Program” in the manual). Once the meter displays “
tUbE
”, insert the reaction tube
into the opening at the bottom of the meter. The hole in the white cap must be lined up with the metal pin
extending from the inside of the hole of the meter. Push the reaction tube all the way into the meter. Press the
<READ> key on the face of the meter. The display will flash the word “
CALC
,” and the results will be
displayed in volume percent (v/v%) Record the results.
KEEP THE METER AND REACTION TUBE
UPRIGHT AT ALL TIMES.
5.
DISPOSAL:
Carefully remove the reaction tube from the meter. Vent the reaction tube by inserting it
completely into the specially designed venting cap unit and remove.
REACTION TUBE AND CAP MUST BE
UPRIGHT AND POINTED AWAY FROM USER AND BYSTANDERS.
Tap the reaction tube on a hard
surface to shake any loose glass to the bottom of the tube, then break the top (green) ampule in the reaction tube
by compressing the sides of the reaction tube. Shake the tube for 15 seconds. After 5 minutes, vent the tube
again. Discard the reaction tube as laboratory waste.
DO NOT REMOVE THE WHITE CAP.
Program B
– Procedure for Testing Water Content up to 100%
(Reagent Systems: HS-ORP + HS-DVP-12)
1.
PREPARATION:
Remove a screw-capped dilution vial from the fluted cardboard carton and a sampling
syringe and a white-capped reaction tube from the reagent box. Check the contents to ensure that all items are
present and intact. Remove the white cap from the reaction tube and discard. Carefully remove a green water
ampule from the cardboard carton and insert it fully into the top of the protective ampule sleeve containing the
grayish white ampule. Return the protective ampule sleeve to the reaction tube with the grayish white ampule
on the bottom and place the reaction tube back into the reagent box.
2.
SAMPLE INTRODUCTION:
Work the plunger of the empty sampling syringe a few times to ensure that it
slides easily. Place the tip of the syringe into the oil sample to be tested (sample must be well mixed and
representative) and slowly pull back on the plunger until it reaches the stop and cannot be pulled further. When
drawing up the sample, make sure there are no air bubbles in the syringe. If air bubbles are present, depress the
plunger again and draw a second sample slowly. Remove the syringe from the oil sample and wipe any excess
oil from the outside of the syringe with a tissue wipe, be sure not to blot the tip of the syringe.
3.
SAMPLE DILUTION:
Remove the screw-cap from the dilution vial. Insert the sampling syringe into the
dilution vial and dispense the oil sample by depressing the plunger. Proceed to mix the solution thoroughly by
repeated drawing and re-dispensing of the solution into the dilution vial with the syringe (3 or 4 times). Using
the same sampling syringe, draw up a sample from the diluted solution wiping any excess liquid from the
outside of the syringe. Dispense the sample into the reaction tube. Insert the black septum (hole on top) by
gripping the reaction tube firmly and pressing down on the septum with your thumb until flush with top of the
tube.
TIGHTLY
cap the tube with the holed, white cap
. NOTE: DO NOT SQUEEZE THE SIDES OF THE
TUBE WHILE INSERTING THE BLACK SEPTUM. DOING THIS WILL RESULT IN LOW READINGS.
4.
REACTION:
Break the bottom (grayish white) ampule in the reaction tube by compressing the sides of the
tube. Mix thoroughly by shaking the reaction tube vigorously for 30 seconds. Allow the reaction to proceed for
a total of 2 minutes.
DO NOT BREAK THE GREEN AMPULE.
5.
ANALYSIS:
Press the <ON> key and make sure the meter is set for Program “
B
” (NOTE: If changing the
program, see “Selecting a Program” in the manual). Once the meter displays “

into the opening at the bottom of the meter. The hole in the white cap must be lined up with the metal pin
extending from the inside of the hole of the meter. Push the reaction tube all the way into the meter. Press the
<READ> key on the face of the meter. The display will flash the word “
