Setup Mode - Hanna Instruments HI21 Series Instruction Manual

SETUP MODE

ENTERING THE PASSWORD
HI21 and HI22 offer a multitude of possibilities from
ON/OFF, proportional or PID dosage to analog recorder
output and from alarm to selftest features.
The Setup Mode allows the user to set all needed charac-
teristics of the meter.
The setup mode is entered by pressing SETUP
and entering the password when the device is
in idle or control mode.
Generally speaking, if the password is not inserted the user
can only view the setup parameters (except for password)
without modifying them (and the device remains in control
mode). An exception is certain setup items, or flags, which
can activate special tasks when set and confirmed.
Each setup parameter (or setup item) is assigned a two-
digit setup code which is entered and displayed on the
secondary LCD.
The setup codes can be selected after password and CFM
are pressed. When CFM is pressed, the current setup item
is saved on EEPROM and the following item is displayed.
Whenever LCD is pressed, the de-
vice reverts back to control mode.
The same is true when CFM is
pressed on the last setup item.
The possible transitions in setup mode are the following:
• Press SETUP to enter the setup mode. The LCD will display
"0000" on the upper part and "PAS" on the lower. The
first digit of the upper part of the LCD will blink.
• Enter the first digit of the password by the  or  keys.
