This meter is user-friendly for laboratory application. INITIAL INSPECTION Carefully unpack the unit and accessories. Inspect for damages made in shipment. If any damage is found, notify your Jenco representative immediately. All packing materials should be saved until satisfactory operation is confirmed.
AC line voltage is correct. If the wrong AC adaptor is supplied, notify your Jenco representative immediately. INSTALLING THE BATTERIES To insert the batteries into the meter, follow the procedure outlined below.
Temperature Conductivity measurement. Coefficient 4. CAL- 10. MAIN DISPLAY- This will be displayed when the For Conductivity and TDS unit enters into the calibration values (3175-307A). mode. Conductivity values (3175-307). 5. AUTO- 11. SECONDARY DISPLAY- Auto ranging indicator For temperature in ℃ display.
Cal- During normal operation, this key will change the mode from “Measure” mode to “Calibration” mode. Mode- 3175-307A selects display mode. normal operation, press this key to sequentially display...
Here are some standard solutions the user can prepare to calibrate the probe of the model 3175-307A/3175-307. Standard solution of 1413uS at 25℃: Accurately weight out 0.746 grams of research grade dried Potassium Chloride (KCL).

TDS Constant TDS is determined by multiplying conductivity (mS) by a TDS factor. The default factor value is 0.65. To change the TDS factor, use the “up” and “down” keys to adjust the value between 0.30 and 1.00. Press “Enter” key to save the new value and go to the next calibration parameter.
are over-ridden: temperature reference (fixed to 25.0℃) and temperature coefficient (fixed to 1.91%). [Note: If you want input K value directly, please press the “Enter” key to go to the K Value Input.] (b) Wait for the values of temperature and conductivity to stabilize for a few seconds.
