  • Page 2 WARNING! 1. DO NOT UNDER ANY CIRCUMSTANCES EXCEED THESE RATINGS: • Voltage is not to exceed 1000 Volts. • Resistance, Capacitance, Logic and Continuity functions are not to be performed on circuits capable of delivering greater than 600 Volts. • Current measurements are not to be performed on circuits capable of delivering greater than 500 Volts 2.
  • Page 3 1. Min/Max Switch • Pressing this button once results in the displayed maxi- mum value of the current reading. • Pressing the min/max button once more results in the displayed minimum value of the current reading. • If pressed a third time “Max Min” will flash on the LCD indicating that the minimum and maximum value are being recorded while the current reading is displayed.
  • Page 4 2. Range Button • Pressing the range button selects the manual ranging mode. • When the range button is pressed RANGE will appear in the upper left of the LCD display. • WHen in the manual range mode, pressing the range button changes the measurement range.
