“MTOWER PLUS” standard settings.
Standard settings are: Probes calibration and operating modes (bleed - inhibitor - biocide).
PASSCODE for “Probe” menu access.
To grant access into “Probe” menu press the wheel from main screen, choose “Setup” and enter the PASSCODE.
If this is the first time here then the PASSCODE is 0000 (factory preset). Press wheel 5 times to grant access.
Otherwise press the wheel 1 time and enter the PASSCODE. Numbers can be selected by rotating the wheel.
“Calibration uS” menu.
“Calibration uS” menu includes conductivity calibration , temperature compensation and manual or automatic temperature
compensation.
Before to begin calibration choose the probe’s scale using FS option (Full Scale)
Conductivity calibration procedure involves a zero calibration (P1) and a 2nd calibration point (P2) that requires a
buffer solution with value near working range. Furthermore TE (Temperature) and CA (Automatica Compensation)
must be set. Note: This procedure assumes that instrument is correctly installed and configured, connected to a
working probe. Calibrate using plant’s temperature otherwise unattended results might occur.
P1 & P2
During this procedure probe must be dry and clean and not installed in plant. Move wheel on “P1” then press wheel,
move cursor on “OK” and press wheel again. Move wheel on “P2” then press wheel to enter into second point calibration
submenu. Prepare buffer solution and dip probe’s sensor on it. Wait until reading value is stable and according to buffer
solution value move wheel until it is the same on display (“uS default” field). End procedure moving cursor on “OK”.
