Page 3: Initial Inspection
GENERAL INTRODUCTION The model 6230M, 6230N, 6231M or 6231N is a precise instrument for the measurement of pH, mV, and temperature. A built-in microcomputer is used to store, calculate, and compensate for all the relevant parameters relating to pH determinations. -
Page 4: Splash Proof
Other features include, low power consumption, percentage of power supply display, electrode offset recognition, electrode slope recognition, built-in buffer coefficients, automatic or manual temperature compensation, auto-saving pH calibration values, and high 50/60 Hz AC noise rejection. This meter is USER FRIENDLY, for field, industrial and laboratory applications. -
Page 5: Changing The Batteries
CHANGING THE BATTERIES When the LOBAT indicator is flashing, the user should check that whether the external AC adaptor is connected to the meter reliably, and if only internal batteries is used, the user should change the batteries. If the voltage of power supply is too low, the meter will display “Sht”... - Page 6 THE KEYPAD ( See Notes 2 and 3 1. ON/OFF key: The ON/OFF key turns the unit ON or OFF. The pH calibration values will not be erased when the unit is turned off. 2. MODE key: 2.1. During normal operation, the MODE key will change the display mode sequentially to pH-AUTOLOCK, mV-AUTOLOCK, pH, mV, RECALL and ERASE.
- Page 7 MEASURE and ▽ keys: Pressing and holding this combination during ERASE mode for about 5 seconds will erase ALL data saved in the non-volatile memory. All 40 sites will be erased completely. Do not use this function until all recorded data has been reviewed or transcribed or downloaded.

Page 8: Modes Of The Meter
MODES OF THE METER ( See Notes 2 and 3 1. pH-AUTOLOCK mode: The meter will display pH and temperature with both pH and AUTOLOCK on. WAIT flashes until the unit detects a stable reading. 2. mV-AUTOLOCK mode: The meter will display mV and temperature with both mV and AUTOLOCK on. -
Page 9: Operational Procedures
OPERATIONAL PROCEDURES Before operation, you should turn on the unit. BUFFER TABLE SELECTION This unit has two buffer sets: 4.01,7.00, 10.01pH and 4.00,6.86, 9.18pH. To change the buffer set, turn off the unit, then press and hold the STAND key while turning on the unit again. - Page 10 1.5 Press the SLOPE key to calibrate. The SLOPE annunciator will stop flashing and stay on. And the WAIT annunciator flashes until the unit detects a stable reading. When a stable reading is reached, the WAIT annunciator will stop flashing and stay off. This means that the second point has been calibrated.
- Page 11 You can press the MODE key to exit for one point pH calibration. The pH annunciator will stop flashing and be on, and the meter is ready for measurements with STAND on but SLOPE off. If dual or three points calibration is needed, go to 2.4.

The WAIT annunciator will flash until the unit determines a stable mV reading. When WAIT stops flashing and stays off, the reading is locked. 1.5 The ATC/Temp probe can be used to measure the sample temperature as required.

OuE/Und Temperature measurement Failed to check or write EEPROM. pH BUFFERS The temperature characteristics of pH calibration buffers 4.00, 4.01, 6.86, 7.00, 9.18 and 10.01 are stored inside the instrument. The buffers used to calibrate the instrument must exhibit the same temperature characteristics as the stored values.
