Page 3: General Introduction
GENERAL INTRODUCTION Thank you for selecting the PM1000 meter. The PM1000 is a precision tool that measures pH, mV and temperature. A built-in microprocessor stores, calculates and compensates for all parameters related to pH determinations including pH electrode temperature characteristics, electrode slope deviations and buffer solutions. -

OPERATIONAL PROCEDURES A. Buffer Set Selection The PM1000 meter has two buffer sets: 7.00, 4.01, 10.01pH and 6.86, 4.00, 9.18pH. The meter is factory pre-set at 7.00, 4.01 and 10.01pH. To change the buffer set, turn off the unit, then press and hold the “Stand”... -
Page 7: Ph Calibration
B. pH Calibration The PM1000 uses one, two or three point calibration. [Note: If the unit uses two or three point calibration, the first point must be 6.86/7.00, and the second point can either be 4.00/4.01 or 9.18/ 10.01.] Calibration with an ATC/Temp probe in the pH-AUTOLOCK mode. -

Rinse the pH or pH/ATC probe in distilled water and immerse it in the third buffer solution (either 9.18/10.01 or 4.00/4.01). Allow temperature reading to stabilize, then press “Slope” key to calibrate. The “WAIT” icon will flash until the unit detects a stable reading. Once the unit calibrates the third point the unit will automatically exit the calibration mode. -

Calibration with an ATC/Temp probe in the pH NON- AUTOLOCK mode. Turn the unit on. Press “Clear” key for 2 seconds, all LCD elements will light up. The meter clears all calibration values stored in internal memory. Connect the pH electrode to the BNC connector and the ATC/ Temp probe to the ATC/Temp connector of the unit: “ATC”... -

Press “Mode” key until “pH” icon and “AUTO” icon light up. Rinse the pH electrode and ATC/temp probe with distilled water and immerse in the sample to be measured. Remove any air bubbles trapped around the probe by shaking or stirring the probe. -

Repeat steps 2~4 of “Measurement with an ATC/Temp probe in the pH NON- AUTOLOCK mode”. D. Temperature Measure The PM1000 can measure temperature independently with the ATC/temp probe without using the pH electrode. Place the ATC/temp probe in the sample. The unit will display the measured temperature. -

be measured. Allow sufficient time for the display to stabilize. The instrument will display the mV value of the sample. pH BUFFERS The temperature coefficient of pH calibration buffers 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. -
