Water Conductivity Circuit Calibration
1.
Disconnect conductivity sensor wires (J4-3 & J4-4).
2.
Using a wire, short together the float pins (J4-5 & J4-6).
3.
Turn power switch ON while holding down Unwrapped and Wrapped buttons to enter
Service Mode.
4.
The Service Mode is password protected, enter password to continue, default
password is: Unwrapped, Wrapped, Rubber and Plastics and Stop buttons pressed in
this order.
Keypad function at this time:
Unwrapped Key:
Wrapped Key:
Rubber and Plastics Key:
5.
Toggle through the menu selections using the keypad to reach Conductivity Setup
and press the Rubber and Plastics key.
6.
Display should be similar to the example below.
Screen Representation
x.x
Water conductivity in uS (micro-Siemens)
NNN
Water conductivity in ADC (Analog to Digital converter) counts (0...255)
y.y
Water quality in ppm (parts per million)
L
"L" is displayed when float switch is activated, "-" when the float switch is not
active
R
"R" is displayed when the Water Quality Sensor is active, "-" when the Water
Quality Sensor is not active.
HH.H
High value threshold (Bad water threshold)
Values larger than this trigger "Bad water quality" error
G.GG
Water conductivity circuit gain
Note: Statim 7000 does not use the conductivity reading to trigger the "No Water, Refill
Reservoir" message. There is a float sensor for that.
7.
By pressing the Rubber and Plastics Key the selection moves between H and G.
8.
Select "G" Water conductivity circuit gain (flashing value on the display), by pressing
the Rubber and Plastics Key.
9.
Adjust G.GG value so the conductivity in ADC counts (NNN) shows
Note: When the NNN value is 186±1 the G.GG value will be approximately 1.00.
10.
Press Stop Key to exit the Water Conductivity Mode and save displayed setting and
enter normal mode of operation, "Select a Cycle" screen.
