7. Statim Autoclave Conductivity Circuit Calibration Instructions
Statim Autoclave equipped with PCB rev 7.x requires Conductivity Circuit Calibration
1. Disconnect conductivity sensors wires
2. Using a wire, make a short on the FLOAT pins (J4-5 and J4-6)
3. Enter Service Mode (Power up unit while holding Unwrapped and Wrapped button
pressed.)
4. Use Unwrapped Key to select next item in the menu or Wrapped Key to select previous
item in the menu until Conductivity Setup is displayed.
5. Press Rubber and Plastic Key to enter Conductivity Setup selection.
Display:
CND=xx.xuS/NNN
L=LL.L H=HH.H G=G.GG
Where
xx.x
water conductivity in
µ
S
NNN
conductivity measurement in ADC (Analog to Digital) counts (0…255)
LL.L
Lower value threshold in
µ
S (No water threshold),
default 0.3
µ
S
Values lower than this triggers “No Water, Refill reservoir” error.
HH.H
High value threshold (Bad water threshold),
default 10
µ
S
.
Values larger than this triggers “Bad Water Quality” error.
G.GG
Water conductivity circuit gain.
Default 1.00
Note: Distilled water readings should be between Low and High thresholds.
6. Check/adjust Low and High threshold values to the default ones.
7. By pressing the Rubber and Plastic Key the selection moves between LO, HI and G
8. Select “G”, Water conductivity circuit gain (flashing value on the display), by pressing
Rubber and Plastic Key
9. Adjust G.GG value so that the conductivity in ADC counts (NNN) shows
186 ±1 count
.
10. Press Stop key to exit Water conductivity mode and save
displayed
thresholds “HH.H”,
“LL.L” and “G.GG” and enter normal mode of operation, “Select cycle” screen.
Note: Keypad functions in Conductivity Setup screen:
Unwrapped Key:
increment current field (the flashing value on the display)
Wrapped Key:
decrement current field (the flashing value on the display)
Rubber and Plastics:
move to next field
Stop key:
