Instruction Manual 1 CON 400/410 INTRODUCTION Thank you for selecting the CON 400/410 waterproof portable meter. This meter is a microprocessor-based instrument that is designed to be user-friendly and allow one-hand operation. It has a built-in real time clock, expanded memory, and many other user-friendly features, all of which are accessible through the membrane keypad.
Instruction Manual 2 CON 400/410 DISPLAY AND KEYPAD FUNCTIONS 2.1 Display The LCD has a primary and secondary display. • The primary display shows the measured conductivity or TDS reading. • The secondary display shows the measured temperature. The display also shows error messages, keypad functions and program functions. See Figure 1. Primary Display 1 SETUP 20 19 READY HOLD ON 18 OFF 3 4 CAL MEM 2 MEAS -8.8.8.
Instruction Manual 2.2 CON 400/410 Keypad The large membrane keypad makes the instrument easy to use. Each button, when pressed, has a corresponding graphic indicator on the LCD. See Figure 2. Some buttons have several functions depending on its mode of operation. Key Function ON/OFF Powers on and shuts off the meter. When you switch on the meter, the meter starts up in the mode that you last switched off from.
Instruction Manual 3 3.1 CON 400/410 PREPARATION Inserting the Batteries Four AAA batteries are included with your meter. 1. Use a Philips screwdriver to remove the two screws holding the battery cover. See Figure 3 below. 2. Remove battery cover to expose batteries. 3. Insert batteries. Follow the diagram inside the cover for correct polarity. 4. Replace the battery cover into its original position using the two screws removed earlier.
Instruction Manual 3.2 CON 400/410 Conductivity Electrode Information The CON400/410 meter uses a conductivity / TDS cell with a sturdy 6-pin connector. Your meter includes a conductivity probe (Part No: ECCONSEN91W / 35608-50) Ultem / Stainless Steel cells with a cell constant of K = 1.0. This conductivity / TDS cell features a built-in temperature sensor for Automatic Temperature Compensation (ATC).
Instruction Manual 3.3 1. CON 400/410 Connecting the probe to the meter Line up the notch and 6 pins on the meter with the holes in the 6-pin connector. Push down and turn the locking ring clockwise to lock into place. See figure below. 2. To remove probe, turn the locking ring counterclockwise on the probe connector. Pull probe away from the meter. CAUTION: Do not pull on the probe cord or the probe wires might disconnect. NOTE: Keep connectors clean. Do not touch connector with soiled hands.
Instruction Manual 4 CON 400/410 CALIBRATION 4.1 Important Information on Meter Calibration Your meter has five measuring ranges. You can calibrate one point in each of the measuring ranges (up to five points). If you are measuring values in more than one range, make sure to calibrate each of the ranges you are measuring. To view current calibration points, see SETUP section Program 2.0 on page 28. The following table lists the corresponding conductivity and TDS ranges.
Instruction Manual 4.2 CON 400/410 Preparing the Meter for Calibration Before starting calibration, make sure you are in the correct measurement mode. When you switch on the meter, the meter begins with the units you shut it off in. For best results, select a standard value close to the sample value you are measuring. Alternatively use a calibration solution value that is approximately 2/3 the full-scale value of the measurement range you plan to use.
Instruction Manual 4.3 CON 400/410 Temperature Calibration MEAS 1413 Your probe features a built-in temperature sensor. The temperature sensor is factory calibrated. Calibrate your 22.3 sensor only if you suspect temperature errors that may have occurred over a long period of time or if you have a replacement probe. ATC CAL 1413 µS °C 22.3 ATC DE MO CAL 22.3 22.3 MI °C ATC MR CAL * If the ATC indicator does not light up, see Program P4.3 22.0 to switch it on. 22.
Instruction Manual 4.4 CON 400/410 Conductivity Calibration The CON 400 and CON 410 meters are capable of up to 5-point conductivity calibration at one point per conductivity range (0.00 - 19.99 µS; 0.0 - 199.9 µS; 0 1999 µS; 0.00 - 19.99 mS; 0.0 - 199.9 mS). All new calibration data will over-ride existing stored calibration data for each measuring range calibrated. Calibrating for Conductivity: 1. If necessary, press the MODE key to select conductivity mode. 2.
Instruction Manual CON 400/410 NOTES: When entering calibration mode, the meter displays the factory default value. If the meter was previously calibrated, the display may seem to “jump” to the factory default value when switching from measurement to calibration mode. This is expected. To exit from Conductivity calibration mode without confirming calibration, DO NOT press the ENTER key in step 6. Press CAL/MEAS instead.
Instruction Manual 4.5 CON 400/410 TDS Calibration 4.5.1 Calibrating for TDS directly For CON 410 meter only The factory default setting for the TDS conversion factor is 0.50. If your solution has a different TDS factor, you can improve calibration accuracy by setting the TDS factor prior to calibration. See page 33 for directions. 1. If necessary, press the MODE key to select TDS mode. 2.
Instruction Manual 4.5.2 CON 400/410 Calibration with Conductivity Standard and TDS factor For CON 410 meter only The concentration of salts dissolved in solution increases the conductivity of that solution. This relationship varies from salt to salt and is roughly linear over a given range for a given salt. The TDS conversion factor is the number used by the meter to convert from conductivity to TDS. Instead of calibrating for TDS directly (described in Section 4.5.
