50/60 Hz AC noise rejection. 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 adaptor supplied with the instrument to make sure that the 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.

Measurement with an ATC/Temp probe in the pH NON- AUTOLOCK mode. Connect the pH electrode to the BNC connector and the ATC/Temp probe to the ATC/Temp connector of the unit. The “ATC” icon will lit up. Press “Mode” key until “pH” icon lit up. Rinse the pH electrode and ATC/temp probe with distilled water and immerse in the sample to be measured.
F. mV (RmV) Measurements Measurement in the mV (RmV)-AUTOLOCK mode. Connect the optional combination ORP electrode to the BNC connector of the unit. Press “Mode” key until “mV” or “RmV” icon and “AUTO” icon lit up. Rinse electrode with distilled water and immerse it in sample to be measured.

[Note: Press “Slope/Enter” key to accept any values changes in each section and automatically advance to the next section. If there are no changes, the unit accepts the current value and proceeds to the next section.] TDS Constant TDS is determined by multiplying conductivity (mS/cm) by a TDS factor.
Wait for the values of temperature and conductivity to stabilize for a few seconds. Press the “Up” and “Down” keys to adjust the reading of the display until it matches the value of the known standard conductivity solution at 25 ℃ . Press the “Slope/Enter”...
I. pH Buffers The temperature coefficient of pH calibration buffers 1.68, 4.00, 4.01, 6.86, 7.00, 9.18 , 10.01 and 12.46 pH are stored inside the instrument. The buffers used to calibrate the instrument must exhibit the same temperature characteristics as the stored values.
