Lift-Off 12.7 mm probe compensated to 0.020" (0.5 mm), 0.010" (0.25 mm) on 8 mm probe.
At 20 °C display changes to PROBE OFF METAL when the compensated probe Lift-
Off distance has been exceeded.
Conductivity Standards Attached to case top, removable for value verifi cation, and temperature sinking to
material to be measured.
Display Graphics LCD 122 × 32 pixels with electroluminescent backlight
Backlight has on and off modes.
Alarm Triggered at upper and lower selected values, indicated by LCD display icons
Calibration Automatically set when set probe sequence is carried out with the probe placed in
turn on the calibration blocks. The probe thermistor detects when a change in tem-
perature of more than 3 °C has occurred since the last calibration and signals the
necessity for re-calibration by illuminating SET at the bottom of the display.
Temperature Measurement By probe thermistor (accurate to 0.5 °C), range 0 °C to +50 °C (32 °F to 122 °F)
The display shows the temperature at which the last measurement was taken.
Automatic Temperature Conductivity measurements are corrected to the 20 °C value when measured at
Compensation other temperatures.
