K VALUE INPUT
11.The instrument will display the conductivity value of the
standard solution with the
CELL K=
flashing.
If the
CELL CONSTANT
has been calibrated by using Step
9 & 10, please press the [
MODE
] key to exit calibration
and return to normal operation.
When you press the [
∆
] or [
∇
] keys, the unit will display
K
value with the
CELL K=
staying on. Using the [
∆
] and
[
∇
] keys, you can now input the
K
value
(from 70% to
130% of the probe basic cell constant).
After release the [
∆
] or [
∇
] keys for 2 seconds , the unit
will display the conductivity value with the
CELL K=
flashing again.
12.Adjust the
K
value until the conductivity value displayed on
the LCD matches the value of the known standard
conductivity solution at 25
℃
.
13.Press the [
ENTER
] key to save the new
K
value
of the cell
or press the [
MODE
] key to exit calibration and return to normal operation.
MEASUREMENTS
The
Model 3173/3173R
is an autoranging instrument. This means that, regardless of the
conductivity of the solution (within the specifications of the instrument), all you need to
do to get the most accurate reading is to put the probe into the sample.
After immersing the probe into the solution, the unit will automatically find the right
range for the solution. During the search, the unit will display “
rAnG
” on the LCD. The
AUTORANGING
will take a few seconds after which the measurement will be displayed.
Press and release the [
MODE
] key to show values in other parameters.
