(6) pH/mV key
: Press this key to switch the pH and mV in the upper LCD in measurement mode.
Increases (↑) the pH values to be calibrated in the calibration mode.
Increases (↑) the set temperature value in the manual temperature measurement
mode.
(7) key
(backlight key)
: Press this key to turn on the backlight on the LCD in the measurement mode.
Decreases (↓) the pH values to be calibrated in the calibration mode.
Decreases (↓) the set temperature value in the manual temperature measurement
mode.
(8) Battery cover
: Uses a 6F22 (006P) 9V battery for this instrument.
(9) Screw for
battery cover
: Secures the battery cover to the main unit.
 Top face of the case
(10) pH sensor connecting jack: Used to connect the sensor. This
product uses the BNC connector.
(11) Temperature sensor connecting jack: Used to connect the
temperature sensor. This product uses the 2.5-mm diode plug.
 LCD
(12) Display of pH or mV : Displays pH values or mV values in the measurement mode.
Display the calibration values in the calibration mode.
(13) Display of temperature : Displays temperature values in all modes.
(14) Temperature unit : Indicates the unit (°C) of temperature measured.
(15) pH unit : Indicates the unit (pH) of hydrogen ion concentration measured.
(16) Voltage unit : Indicates the unit (mV) of voltage measured.
(17) REC : Lights up when the maximum and minimum pH values or the maximum and
minimum voltage values are being logged. (MAX/MIN logging mode)
(18) MAX : Lights up when the maximum pH or voltage value is displayed.
(19) MIN : Lights up when the minimum pH or voltage value is displayed.
(20) BAT : Lights up when battery power is insufficient. Replace with a new battery
(6F22, 006P).
(21) ATC : Lights up when the temperature sensor is connected.
(22) Display of time/voltage: Indicates the time elapsed since logging (REC) started while in the MAX/MIN
logging mode. Displays "CA" and voltage in the calibration mode.
