Page 7: Introduction
I N T R O D U C T I O N Thank you for purchasing the EcoSense pH1000A, a precise laboratory benchtop meter 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. -
Page 8: Getting Started
6 “AA” alkaline batteries. Check the label on the AC adaptor supplied with the instrument to make sure that the AC line voltage is correct. If the wrong AC adaptor is supplied, notify your YSI representative immediately. -
Page 9: Key Pad
KEY PAD Description Power key. Press and hold for 3 seconds to power on the meter. Pressing this key will also turn the instrument off. Up and down arrow keys are used to manually enter temperature values. They have no effect on the unit when operating in ATC mode. -
Page 10: Main Display
MAIN DISPLAY Number Description WAIT: This will be displayed when the unit is still waiting for a stable reading. BAT: Low battery indicator. pH: Unit and mode indicators. mV: Unit and mode indicators. ATC/MAN: ATC indicator will be displayed if a temperature probe is connected, otherwise the MAN indicator will be displayed. -

I N S T R U M E N T O P E R A T I O N BUFFER SET SELECTION The pH1000A has two buffer sets: 7.00, 4.01, 10.01 pH and 6.86, 4.00, 9.18 pH. The 7.00, 4.01 and 10.01 pH buffer set is the factory default. The pH1000A will automatically recognize the buffer used as long as the correct buffer set is selected and the electrode is in good operating condition. -

4. Press and hold the Stand key for 2 seconds to calibrate. The “WAIT” icon will flash until the unit detects a stable reading. The buffer used for the first point will remain lit on the display while the remaining two buffers start to flash. -
Page 13: Viewing The Electrode Efficiency After Calibration
A single electrode efficiency will be displayed after a single point calibration. This efficiency will always equal 100%, as the theoretical Nernst Slope will always be used for the observed slope. This is why YSI recommends at least a two point calibration. -
Page 14: Ph Measurements
A single electrode efficiency will also be displayed after a two point calibration. This is the efficiency between the two calibration points. Two separate efficiencies will be displayed after a three point calibration, one for the slope between 4.01/4.00 and 7.00/6.86 and another for the slope between 7.00/6.86 and 10.01/9.18. -

MEASUREMENTS ORP measurements can be made with the YSI 115-1 (item # 605376) electrode, but any ORP electrode with a BNC connection can be used. MEASUREMENTS IN THE mV AUTOLOCK MODE 1. -

T R O U B L E S H O O T I N G Display Possible Cause(s) Possible Solution(s) 1. Stand was pressed before 1. Press Clear key, allow sufficient “Er1” the electrode and ATC/Temp time for the electrode and ATC/ probe settled to within +/- Temp probe to stabilize, re-press 1.5 pH of the buffer value. -

Page 20: Appendix A: Temperature Coefficient Of Ph Buffers
C O E F F I C I E N T O F p H B U F F E R S The temperature coefficients of pH calibration buffers 4.01, 7.00, and 10.01 (e.g. YSI buffers), as well as the 4.00, 6.86, and 9.18 buffer set, are stored inside the instrument. The buffers used to calibrate the instrument must exhibit the same temperature characteristics as the stored values.
