Page 5: Introduction
1. INTRODUCTION Thank you for purchasing our PC 700 series benchtop meter. This microprocessor-based meter is economical and simple to use. The design incorporates a large LCD for clear viewing, yet offers a small footprint to conserve space. The PC 700 measures pH, mV (ORP), conductivity, or TDS simultaneously with temperature (ºC or ºF). -
Page 6: Getting Started
2. GETTING STARTED 2.1 Keypad Functions Powers the meter on and off. Upon power on, the meter automatically begins in the mode that was last used. Calibration and memory values are retained even if meter is unplugged. Toggle between available measurement modes— pH/Temp, mV/Temp, Conductivity/Temp, or TDS/Temp. -

3. CONDUCTIVITY ELECTRODE The PC 700 includes an electrode with a nominal cell constant of k = 1.0, built-in temperature sensor, and 1 meter cable. The Ultem body housing has good chemical resistant properties. The electrode design offers fast temperature response and reduces air entrapment, ensuring accurate, repeatable, and stable readings. - Page 9 The following calibration standards are automatically recognized; USA buffer group 1.68, 4.01, 7.00, 10.01, 12.45 NIST buffer group 1.68, 4.01, 6.86, 9.18, 12.45 See Section 9.6 to change the buffer group 1) Press as needed to select pH. 2) Dip the pH and ATC electrodes into pH buffer and press .

Page 10: Millivolt (Mv) Offset Adjustment
4.2 Millivolt (mV) Offset Adjustment Oxidization Reduction Potential (ORP or Redox) is not a precise measurement, but is useful as a relative indicator. As such, mV offset adjustment is not meant to enhance accuracy, but rather to make readings comparable to a reference. Commercial ORP solutions are often used as a check standard in which a meter/electrode system are verified to be close to a given value, instead of being used as a calibration standard in which adjustments are made in an attempt to... -
Page 11: Single Or Multi-Point Calibration
If you only use calibration standards that are listed in TABLE 1, automatic calibration is recommended. If you intend to calibrate with one or more standards that are not listed in TABLE 1, the PC 700 must be set for manual calibration instead. The factory default is automatic conductivity calibration. -
Page 12: General Calibration Tips
Use Multi-Point Calibration for individual calibration in each range. This will restrict an individual calibration so that it is applied to one range only. When using multi-point calibration, perform a calibration in each range that you expect to use for best results. The factory default is Single-Point Calibration. -

6. CONDUCTIVITY AND TDS MEASUREMENT 6.1 Taking Measurements Rinse the electrode with de-ionized or distilled water before use to remove any impurities. Gently shake excess water droplets. Dip the probe into the sample beyond the upper steel band (utilize the fill line on the outside of the probe guard for reference). -
Page 15: Hold Function
7. HOLD FUNCTION For prolonged observation of a reading, press during measurement mode to freeze the display. The “HOLD” indicator will display when the reading is held. To release the held value and resume measurement, press again or insert the held value into memory by pressing 8. -

9. SETUP FUNCTIONS Use the setup feature to customize your instrument operation. First, select the appropriate measurement mode you wish to adjust by pressing until the desired units are displayed (i.e. pH, mV, Conductivity, or TDS). During measurement, press and hold for 5 seconds to enter SETUP mode of the parameter being measured. -
