to or subtracted from the setpoint value for a high (ON/OFF
or PID) or low (ON/OFF or PID) setpoint respectively. The
same is true for Alarm relay delta value for setpoint 2. A
small fixed hysteresis (0.2 pH for pH and 30 mV for ORP)
must be passed to have the alarm turned off (for a high
alarm the alarm is turned off below high alarm - hysteresis,
while for a low alarm the alarm is turned off above low alarm
+ hysteresis).
(23): The actual start of a cleaning action depends on how
relay 3, relay 4 and the Advanced Cleaning parameters have
been configured.
(24): If the item is set to “On”, the “m” tag near the second-
ary display will be fixed on.
If the item is set to “OFF” the connector for the Potential
Matching Pin must be left floating. Failure to do so may
cause damage of the reference electrode.
(25): When the Digital Transmitter is in use, the correspon-
dent setting in the digital transmitter is used and this item is
not visible.
(26): This item is not visible for models without PID or with-
out the second setpoint.
(27): An SMS will be sent to this telephone number (if differ-
ent from “- - - - - - - - - - - - - - - - - - - -”) when an error
(configured for the SMS sending) occurs.
(28): This item sets the maximum number of SMS that the
instrument can send. Before this number reaches 0, an ad-
vising message will be sent to the phone number P.02 (and
P.03). This feature has been introduced to avoid the discharg-
ing of the credit of the SIM card. Once all the available
messages have been sent, the user is supposed to extract the
SIM card from the instrument and check the remaining credit
and expiration date of the card.
The item shows always the remaining available number of
SMS that can be sent, so its value is decremented every SMS
submission.
If the user sets this item to “222”, then no check will be made
on the maximum number of SMS and the instrument could
send an unlimited number of messages. In this case the item
value will not be decremented and no check will be made on
