OPERATIONAL GUIDE CONNECTIONS Plug the 12 VDC adapter into the power supply socket. Note: This instrument use non volatile memory to retain the calibration parameters and all the other settings even when unplugged. Connect the EC/TDS probe to the 7-pin connector. Tighten the threaded ring. Make sure the probe sleeve is properly inserted, as shown below: POWER 12VDC PROBE RS232 INSTRUMENT START-UP • Turn the instrument on by pressing the ON/OFF switch.
Notes: • • • • If the meter displays “----”, the reading is out of range. • TDS reading is obtained by multiplying the EC reading by the TDS factor, which has a default value of 0.50. It is possible to change the TDS factor in the 0.40 to 0.80 range by entering setup mode and selecting the “tdS” item (see SETUP for details). • When the use of an alternate function (SETUP, TC, GLP or CALT) is requested, press and hold the ALT key first, and then the second key.
To select the desired option press ATC until the option is displayed on the LCD. If temperature compensation is active, measurements are ATC compensated using the temperature coefficient (default value 1.90 %/°C). To change the temperature coefficient, enter the setup mode and select the “tc” item (See SETUP for details, page 14). The current temperature coefficient can be quickly viewed by pressing ALT+TC keys. The value is briefly displayed on the secondary LCD.
Select the desired value with the ARROW keys, if necessary. OR When the reading is stable, “CFM” tag starts blinking on the LCD, asking for confirmation. Press CFM to confirm calibration. CAL CFM BUF CFM The instrument displays the “Stor Good” message and returns to measurement mode. Notes: • If the uncalibrated reading is too far from the expected value or the temperature value is out of 0 – 60 ºC range, calibration is not recognized.
The “BUF” and “CAL” tags are displayed. The primary LCD displays the uncalibrated NaCl reading in percentage. The secondary LCD displays “100”. % CAL NaCl BUF When the reading is stable, “CFM” tag starts blinking on the LCD, asking for confirmation. Press CFM to confirm calibration. % CAL NaCl CFM BUF CFM The instrument displays the “Stor Good” message and returns to measurement mode. Notes: • If the uncalibrated reading is too far from the expected value, calibration is not recognized.
TEMPERATURE CALIBRATION (for technical personnel only) The calibration is a 2-point procedure at 0.0 and 50.0 ºC. • Immerse the probe in a 0 ºC temperature bath. • Press ALT+CALT keys to enter temperature calibration mode. • The lower LCD displays “0.0 ºC”, “BUF” and “CAL” tags blinking. • When the reading is stable, “CFM” tag starts blinking. • Press CFM to confirm. The lower LCD displays 50.0 ºC. • Immerse the probe in a 50 ºC temperature bath. • When the reading is stable, “CFM” tag starts blinking.
CONDUCTIVITY VERSUS TEMPERATURE CHART The conductivity of an aqueous solution is the measure of its ability to carry an electrical current by means of ionic motion. The conductivity invariably increases with increasing temperature. It is affected by the type and number of ions in the solution and by the viscosity of the solution itself. Both parameters are temperature dependent.
SETUP Setup mode allows viewing and modifying the instrument parameters. To enter setup press ALT+SETUP keys when the meter is in measurement mode. ALT SETUP “Set” is displayed on the primary LCD. The secondary LCD displays the code of the current setup item. Select the desired setup item using the ARROW keys. Press CFM to confirm. OR CFM Note: If ALT+SETUP keys are pressed before item confirmation, the meter exits SETUP mode and returns to measurement mode.
Note: Press ALT+SETUP keys before confirmation to escape without changing the previously set value. The following table lists the setup items, their valid range of values and the factory settings (default): Item Description Valid values Default tc Temp.compensation coeff. 0.00 to 6.00 %/ºC 1.90 tcE Temp.compensation mode Atc, Mtc, notc Atc rEF Reference temperature 20.0 ºC, 25.0 ºC 25.0 ºC tdS TDS factor 0.40 to 0.80 0.50 CEL Cell constant (K) 0.500 to 1.700 1.
By repeatedly pressing RANGE, GLP data is displayed in the following order: Last calibration date: RANGE Last calibration year: Last calibration time: Cell constant value (K): Offset value: This information is displayed only if the last calibration was performed at 0.00 µS. Calibration solution used: BUF If the cell constant was changed after calibration (through the “CEL” setup function), this information is not displayed.
If RANGE is pressed when the last parameter is displayed, the meter returns to measurement mode. Notes: • To exit GLP mode at any time press ALT+GLP keys. • If the calibration procedure was never performed, after displaying the ID code the LCD will show the “no CAL” message blinking. Press RANGE or ALT+GLP keys to return to measurement mode. • Last calibration data is available for EC and NaCl only. No calibration data can be recalled for TDS.
PROBE MAINTENANCE Rinse the probe with clean water after measurements. If more cleaning is required, remove the probe sleeve and clean the probe with a cloth or a nonabrasive detergent. Make sure to reinsert the sleeve onto the probe properly and in the right direction. After cleaning the probe, recalibrate the instrument. The platinum rings are sustained with glass. Take great care while handling the probe.
