working temperature. If not, adjust the pH meter to read the correct value. Note: The °C knob is not effective during pH 7 calibration, since pH 7 is used as reference. pH CALIBRATION HI 8427: • Connect the simulator to the pH meter using the HI 7858/1 cable provided. HI 8427 pH/mV CALIBRATOR pH • • • • • Switch the pH meter on and select pH 7 on the simulator. Make sure that the LOW BATTERY LED is not lit. If it is lit, change the battery of the simulator before performing the calibration.
• mV (ORP) CALIBRATION HI 8427: • Connect the simulator to the mV (ORP) meter using the HI 7858/1 cable provided. • HI 8427 pH/mV CALIBRATOR pH • Switch the mV meter on and select the desired mV value on the simulator. Make sure that the LOW BATTERY LED is not lit. If it is lit, change the bat-350 tery of the simulator bemV fore performing the calibration.
pH VALUES AT VARIOUS TEMPERATURE CABLE HIGH IMPEDANCE TEST HI 8427 only: • Connect the simulator to the cable (e.g.HI 7855). • Press the HIGH IMPEDANCE key and observe the LEAKAGE LED while you are turning the simulator rotary knob to any pH/mV value. • • If the LED does not light, the cable and connector going to the meter are in perfect condition. If the LED is lit, it means there is a leakage problem with the cable and connector and you should check/replace it.
ACCESSORIES BATTERY REPLACEMENT The instruments use a 9 volt battery that lasts for approximately 100 hours or 500 hours of continuous use with HI 8427 and HI 931001 respectively. In the event of dead battery the LOW BATTERY LED of HI 8427 will be lit or two additional decimal points will be displayed on HI 931001. HI 710001 Soft carrying case for HI 931001, dimensions 230 x 100 x 50 mm HI 7858/1 Extension cable with 3 mm diameter (0.12"), 1m (3.
