General Information

B. Operation of pHuture ® Solid State System

The Orion 620 pHuture Solid State System utilizes solid state technologyto measure pH and temperature. This system is an active electronic one,where the potential developed at the sensing surface is dependent on thesolution pH. This surface potential is measured with a transistor. Thechange in potential is translated to a temperature compensated pH readingby the meter.

Due to these special characteristics of this system care must be taken toensure that the device is handled properly:

• Always turn the meter off prior to connecting or disconnectingthe probe.

• The system is protected against electrostatic discharge (ESD).However, as with any electronic device, care should be taken toprevent large static discharges from contacting the probe.

Using the Instrument

Chapter IVUsing the Instrument

A. Power UpPressing the power key will turn on the meter. The entire display (allannunciators) will be displayed for 2 seconds. Next, the number “620”will then be displayed for 2 seconds. Then the calibration buffer(s) usedfor any previous calibration will be displayed in the lower display field for2 seconds.

The calibration buffer indicator(s), ▼ , along the bottom of the display,will then light up and remain displayed along the bottom of the display,until a new calibration is performed. For example:

• If a one-point calibration had been previously performed, thepH 7 buffer indicator will be displayed.

• If a two-point calibration with pH 7 and pH 4 buffer had beenpreviously performed, the pH 7 and pH 4 indicators will bedisplayed.

Once all power up procedures have been completed the meterautomatically advances to measure mode.

NOTE: If this is the first time the meter has beenpowered up it is recommended that the InstrumentCheck Out procedure be performed before using themeter for pH measurements.

Manual Buffer Option

When the manual buffer option function is entered the current settingwill be displayed as STD “57O” or SET “5E7” on the temperature display.When the “57O” option is selected, calibration may only be performedwith standard buffers, pH 4.01, 7.00 and 10.01. When the “5E7” option isselected, calibration may be performed with user defined buffers withinthe range of 0 to 14 pH.

D. Millivolt ModeScroll through Mode until MEASURE (mV) is displayed.The mode sequence is:MEASURE (pH) > CALIBRATE > MEASURE (mV) > SETUP

While in the millivolt mode:

• The MEASURE annunciator will blink to distinguish it from thepH Mode.

• “ready” will be displayed the same way as it now is in theMEASURE (pH) Mode

Direct Display of Millivolts:

The mV Mode displays millivolt readings in two ways:

1. If the number is not calibrated, the display will read “----”. Theuser must perform at least a one point calibration before millivoltscan be displayed.

2. If the meter is calibrated, the sensor reading will be converted to amillivolt reading based on a normal Nerstian slope of 59.16millivolts per decade of pH.

Error codes (E-20, etc.) will be displayed in the millivolt mode forthe same reasons they are displayed in the pH mode (reading is out ofrange, etc.). Check error display code section in the appropriate meterand/or probe instruction manual for appropriate action to be taken.

Calibration and Measurement

Chapter VCalibration and Measurement

A one or two buffer calibration should be performed before pH ismeasured. It is recommended that at least two buffer calibration usingbuffers that bracket the expected sample range be performed at thebeginning of each day to determine the slope of the electrode. Thisserves the dual purpose of determining if the pHuture Solid State systemis working properly and storing the slope value in the meter memory.The Orion 620 Meter features both autocalibration when using standardbuffers, 4.01, 7.00 and 10.01, as well as manual calibration whennon-standard buffers are required.

A. AutocalibrationAutocalibration is a feature of the Orion 620 Meter that automaticallyrecognizes the standard buffers 7.00, 4.01 and 10.01. Simply select thebuffer sequence that best fits your application, choose between, a onepoint autocalibration with pH 7, a 2 point calibration using 7-10 or 7-4and a 3 point calibration using 4, 7, 10.
