To generate a New Lot:
• Press 

 while in 

pH Measure

 mode.

• Press 

.

• Use 

 or 

 to select the Log option.

• Press 

 and use 

 or 

 to highlight the New

Lot option.

• Press 

 to generate a new manual lot. A pop-up menu will

be displayed asking for confirmation.

• Press 

 to confirm or press 

 to escape without

saving and return to the Log options.

Alarm

This option allows the user to select the alarm settings: Alarm State and Alarm Limits. If the Alarm option
is enabled, a continuous double beep will be heard, along with the “

Alarm

” indicator blinking on the LCD,

each time the set limits in Measure mode are exceeded.

Note:

Alarm Beeper must be set On for audible beep to be heard.
See: System Setup > Beeper > Alarm.

Alarm State

Three settings are available for the Alarm State option:

Disabled

 - the alarm will be disabled.

Inside Limits

 - the alarm state will trigger when the measured value is inside the set limits.

Outside Limits

 - the alarm state will trigger when the measured value is outside the set limits.

To set the Alarm State:

• Press 

 while in 

pH Measure

 mode.

• Press 

.

• Use 

 or 

 to select the Alarm option.

• Press 

 and use 

 or 

 to highlight the Alarm

State option.

• Press 

 and use 

 or 

 to highlight the desired

option.

• Press 

 to confirm your selection or press 

 

to cancel

operation.

Alarm Limits

This option allows the user to set the alarm limits for the measured value.

Note

: The Alarm High value can not be lower than the Alarm Low value.

Relative mV MEASUREMENTS

To measure the Relative mV of a sample:

• Press 

 then 

 

(select channel first for 

HI 5222

).

• Verify if a current calibration has been made.
• If required, conduct the single point Rel mV calibration.

Verify the tip of the electrode is immersed into the known
solution or ORP standard.

• Press 

. Use 

 and 

 arrow keys set the

standard value. Press 

 to store the calibration.

• Press 

 then 

 (select channel first for 

HI 5222

).

• Place calibrated sensor tip into the sample to be analyzed. The

instrument will display the measured Relative mV value on the
LCD, together with a short GLP information about the last
calibration or Offset: 0.0 mV no Rel mV calibration was
performed.

Notes:

If the ORP sensor is not in solution or the measured mV
potential is out of range, “

will be displayed on the

LCD.
