(for Redox/ORP sensor inputs) and temperature by pressing the front panel keypad. When the HH4-PH is turned on, the display will indicate various power up messages and then settle into the measurement mode. The position of the decimal point allows the user to determine which range is currently selected. -
Page 4: Operation
Operation The HH4-PH digital pH meter is operated by pressing the on/off button. The following display sequence is executed during startup: 8.8.8.8 Display check Company name PHX.X Software version number This sequence will take around eight seconds then the display will indicate the current pH value. -

Note: When the HH4-PH is set to manual, the manually set temperature will be displayed when the display is cycled to read temperature - if the temperature probe is not connected. When the HH4-PH is set to automatic, the manually set temperature will not be displayed. - Page 8 APdt (set Auto Power Down Time) Press the ^ “On/Off” button or the v “pH/mV/Temp” button to select the Automatic Power Down Time (auto turn off time). The time is programmable over the range of 0 to 250 minutes. Note: if continuous operation is required, select 0 to disable the auto turn off function.

Page 10: Calibration
Calibration pH Calibration - 2 methods The HH4-PH has provision for two methods of pH calibration, a single points may be used for routine calibration, whilst a two point method should be used for initial calibration, critical applications, when the electrode is replaced or for periodical maintenance etc. - Page 11 End followed by FUNCEndand the system gain will be adjusted so that the display will match the corrected value. Two point calibration - see alsp HH4-PH two point calibration procedure example which follows.

- Page 13 pH uncalibration This function sets the instrument calibration back to the factory calibrated value and closely matches that of an ideal electrode. Uncalibrate is useful as a temporary measure when the pH electrode is replaced and on the spot recalibration is difficult or when a calibrating error exists due to incorrect calibration.

Page 14: Errors And Status Messages
Errors and Status Messages The status message which represent conditions and errors, are as follows: batt (low battery voltage) Indicates that the battery voltage has reached approximately 6.4V. The unit will continue to operate - a new battery should be fitted as soon as possible. CAL Err (calibration error) If the display is in overrange during calibration and an attempt is made to calibrate, then this message will be displayed. -
