[. . . ] Instruction Manual PC 300 Waterproof Hand-held pH/Conductivity/TDS/Temperature Meter 35631-00 Technology Made Easy . . . 68X248908 Rev3 01/04 Preface This manual serves to explain the use of the Waterproof PC 300 hand-held meter. It functions in two ways, firstly as a step by step guide to help you to operate the meter. It is written to cover as many anticipated applications of the Waterproof PC 300 hand-held meter as possible. If there are doubts in the use of the PC 300, please do not hesitate to contact the nearest Eutech Instruments/ Oakton Instruments Authorized Distributor. [. . . ] To re-select the Auto-ranging function, repeatedly press the RANGE key until the "MEAS" indicator appears without blinking. Figure 22 - Manual ranging NOTES If the value of the solution you are measuring is higher than the range selected "Or" will appear on the primary display. You will have reset the manual ranging function each time you turn the meter off. Figure 23 - Out-of-range 27 Instruction Manual PC 300 6 HOLD FUNCTION This feature lets you freeze the display for a delayed observation. HOLD can be used any time in MEAS mode. 1. To hold a measurement, press the HOLD key while in measurement mode. "HOLD" will appear on the display. 2. To release the held value, press the HOLD again. Continue to take measurements. Figure 24 - HOLD function NOTE: · · · This meter shuts off automatically after 20 minutes of last key press. If the meter is shut off either automatically or manually, the HOLD value will be lost. When this feature is switched on, and when a reading is stable for more than 5 seconds, the display will automatically "HOLD" the reading. To switch on or off the auto endpoint feature, see SETUP program P3. 1 in Section 7. 4 for pH and SETUP, program P7. 1 in Section 7. 8 for conductivity/TDS. 28 Instruction Manual PC 300 7 ADVANCED SETUP FUNCTIONS The advanced setup mode lets you customized your meter's preferences and defaults. This Waterproof handheld meter features different sub-groups that organize setup parameters. The sub-groups are: For pH P 1. 0 P 2. 0 P 3. 0 P 4. 0 View calibration data (CAL) View electrode data (ELE) Unit Configuration (COF) Reset to factory default P 5. 0 P 6. 0 P 7. 0 P 8. 0 For Conductivity & TDS View calibration data (CAL) View electrode data (ELE) Unit Configuration (COF) Temperature (tPr) settings (rSt) P 9. 0 Reset to factory default settings (rSt) See Figure 25 on next page. 29 Instruction Manual PC 300 Figure 25 - Overall view of SETUP programs for pH (on left) and conductivity/TDS (on right) 30 Instruction Manual PC 300 7. 1 1.
