Step 2: Prepare Bresle Method Patch
Option A: DeFelsko PosiPatch
a) Turn the PosiPatch and magnetic ring upside down. Place the
PosiPatch into the magnetic ring ensuring the arrows align
with the injection port. Do not touch the PosiPatch’s interior.
b) Carefully place the magnetic ring on the steel surface. When
used on vertical surfaces, position the injection port between
the 4 o’clock and 8 o’clock points before attaching the
magnetic ring to the surface.
c) Slowly inject 3.0 ml of DI water into the port using the plastic
dispensing tip. The air within the PosiPatch automatically
escapes through the air-permeable membrane.
Step 1: Obtain Background (Blank) Conductivity
Measurement (γ
1
)
The Gage automatically displays the previous
background measurement, if any. This measurement can be
reused and step (c) to step (e) can be skipped by pressing the
button.
a) Pour at least 4 ml (milliliters) of deionized (DI) water into the
supplied cup (to prevent contamination of the water source).
b) Fill the syringe completely with DI water from the cup (slightly
more than 3 ml).
c) Completely fill the PosiTector SST probe’s test cell with water
from the syringe (approximately 1 ml).
d) Wait until the measurement stabilizes (up to 5 seconds), then
press the button to save a new background conductivity
measurement (γ
1
) and the water temperature (T
1
).
e) Use the syringe to draw all of the water from the test cell.
Shake any remaining water out of the test cell.
f) With the syringe pointing up, expel the air and excess solution
from the syringe until there is 3.0 ml of DI water remaining.
