OFF RANGE 8 9 CABLE HIGH IMPEDANCE TEST pH VALUES AT VARIOUS TEMPERATURE HI 8427 only: Temperature has an effect on pH. The calibration buffer solutions are effected by temperature changes to a lesser degree than normal solutions (see table below). This pH simulation will not be affected by this chemical behavior. Note: With HI 8427 your pH meter will always show the pH buffer solution at the standard temperature of 25ºC. · 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. HIGH IMPEDANCE · 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.
