"ACCU-MAX II" DUAL CONTROLLER
                   by Ultralife Reef Products
                     Operating Instruction
 
1. Unpack meter, calibrating\verification solutions, dual
electrode from package.
2. Connect electrode to meter. The dual electrode has two BNC
connections, connect the 'PH' lead to 'PH, connect the 'ORP' lead
to 'ORP'. Connect power cord to proper power supply
3. For PH calibration: Put electrode into ph 7.00 buffer
solution. Slide switch to right-side (M). Adjust slotted screw
marked 'CAL' to display value 7.00. Remove electrode from
solution, rinse in distilled water to clean electrode. Place
electrode in ph 4.00 buffer. Adjust slotted screw marked 'SLOPE"
to display 4.00.  The electrode is now calibrated properly.
4. Slide switch to left-side (S). Adjust slotted screw marked
'SET' to desired PH setpoint. Value on display will reflect your
desired setpoint.
5. To adjust desired ORP setpoint. Slide switch to left-side (S).
Adjust slotted screw marked 'S' to desired ORP setpoint. To
Verify if your ORP electrode is functioning properly, follow
procedure on Electrode Verification Instructions.
6. Slide both the ORP and PH slide switches to right-side (M).
the meter is now set to monitor\control both PH and ORP.
7. Plug devices to be controlled (ozonizers or C02 systems, etc)
into 3-prong power output sockets on power module. Place the 
Electrode into aquarium or sump. Be sure that the White Top 
of the Electrode is at all times ABOVE the water level.
8. The control span (ON\OFF control) is factory preset and should
not require any adjustment. The control span sensitivity can be
adjusted if so desired. This adjustment is very sensitive and
should only be done after controller has been in use for some
time and only if the preset control span is unacceptable.
9. If you need to change the control sensitivity of either PH or
ORP the following instructions are applicable to both. The
Slotted screw marked 'D.B.' (Dead Band) will allow you to adjust
the sensitivity from 0-5%. The control sensitivity (On\Off
control) can be adjusted more sensitive by turning screw counter-
clockwise. And less sensitive by turning clockwise. Care should
be taken when adjusting the sensitivity, very small adjustments
can make quite large changes in the control sensitivity. The
easiest way to adjust the sensitivity is while the slide switch
is to right-side (M), first make note of the ON\OFF cycle span. 
Make very small adjustments to slotted screw marked 'D.B.'. You
must again watch unit go through the ON\OFF cycle, making note of
the cycle span. If the span is acceptable, you need do nothing
else, the unit will now control to your desired span. If you
would like to make further adjustments, follow above procedure
again. Be sure to make note of the cycle span each time.
