TAKING MEASUREMENTS Press the ON/OFF key to turn the meter on. Immerse the probe into the solution to be tested. The sleeve holes must be completely submerged. Tap the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve. If needed, press the RANGE key repeatedly until the desired range (EC, TDS, NaCl) is selected on the LCD. Allow for the reading to stabilize. The upper LCD displays the measure in the selected range while the temperature is displayed on the lower LCD.
AUTORANGING The EC and TDS scales are autoranging. The meter automatically sets the scale with the highest possible resolution. By pressing ALT+FIXED, the autoranging feature is disabled and the current range is frozen on the LCD. "F1" symbol blinks on the LCD. To restore the autoranging option press ALT+FIXED again. Note: Autoranging is automatically restored if the range is changed, if the setup or calibration modes are entered and if the meter is turned off and back on again.
EC/TDS/M Ω CALIBRATION EC/TDS/MΩ Calibration is a 1-point procedure. Selectable calibration points are: 0.0, 84.0µS, 1413µS, 5.00mS, 12.88mS, 80.0mS,111.8mS. To enter EC calibration select the EC range and press the CAL key. Note: TDS reading is automatically derived from the EC reading and no specific calibration for TDS is needed. Pressing CAL while TDS range is selected has no effect. Rinse the probe with some of the calibration solution or deionized water. Immerse the probe into the solution.
III IV V In order to minimize any EMC interference, use plastic beakers. The meter uses 1.90%/ C compensation factor during calibration. If the setup item "tc" has been set to a different value, when exiting the calibration mode the value displayed on the upper LCD could be different from the nominal buffer value. It is possible to set the cell constant value directly without following the calibration procedure. To set the cell constant enter the setup mode and select "CEL" (see SETUP for details).
TEMPERATURE CALIBRATION (for technical personnel only) The calibration is 2 points at 0.0, 50.0 C. • Immerse the probe in a 0 C temperature bath. • Press ALT+CALT to enter temperature calibration mode. • The lower LCD displays "0.0 C"; "BUF" and "CAL" tags appear. • When the reading is stable, "CON" symbol starts to blink. • Press ALT+CFM to confirm. The lower LCD displays 50.0 C. • Immerse the probe in a 50 C temperature bath. • When the reading is stable, "CON" symbol starts to blink.
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 is used to view or change the instrument parameters. To enter setup press ALT+FNC when the meter is in measurement mode. "Set" is displayed on the upper LCD. The lower LCD displays the blinking code of the current setup item. Select the desired setup item using the V or W key. Press ALT+CFM to confirm. Note: If ALT+FNC are pressed before item confirmation, the meter will escape and return to measurement mode.
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 %/ C 1.90 tcE Temp. compensation mode Atc, Mtc, notc Atc tdS TDS factor 0.40 to 0.80 0.50 CEL Cell constant (K) 0.500 to 1.700 1.000 AoF Auto-Off enabled On, OFF OFF YEA Year 1999 to 2098 1999 dAt Date (DD.MM) 01.01 to 31.12 01.01 hou Time (hh.mm) 00.00 to 23.59 00.
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. If the cell constant was changed after calibration (through "CEL" setup function), this information is not displayed.
DATA TRANSFER TO PC Connect the meter to a PC through the RS232 output (#11 on page 4). Use HI 920010 (9 to 9-pin) connection cable. The meter must be in measurement mode to communicate. The meter RS232 port is optoisolated and transmits data with a Baud rate of 2400 bps. Retrieve the GLP data and request the meter parameters and the current reading (of the current range only) from the PC directly. It is also possible to send a command from the PC to set the meter in a different range.
