OPERATION

• Data Hold Mode:  Press the “ HOLD ‘” button to hold the present reading on the display, will appear on the display as an indicator.  To exit the Data Hold mode, just press this button again, disappears.

• Relative Mode: Selecting relative mode makes the meter store the present reading as a reference for subsequent measurements and zero the display.Press the button. The meter enters relative mode and stores the present reading for subsequent measurements. The triangle symbol appears on the display as an indicator. The display reads zero. When a new measurement is taken, the display shows the difference between the reference and the new measurement. To exit Relative mode, press the button again and the disappears.
  Note:
  (i) For measurement functions which have both autorange mode and manual range mode, the meter changes to manual range mode automatically when you select Relative mode. Select the desired manual range before you select Relative mode.
  (ii) When you use Relative mode, the actual value of the object under test must not exceed the full-range reading of the selected range. Use a higher range if necessary.

• Manual Ranging and Autoranging: The meter defaults to autorange mode in measurement functions which have both autorange mode and manual range mode. When the meter is in autorange mode, “Auto” is displayed.
  Press the RANGE/ button to enter the manual range mode. The symbol “Auto“ disappears. E ach press of the RANGE/ button increases the range. When the highest range is reached, the meter scrolls to the lowest range. To exit the manual range mode, press and hold down the RANGE/ button for about 2 seconds. The meter returns to the autorange mode, and “Auto“ appears.
  Note: Only voltage, current and resistance measurement functions have autorange mode and manual range mode.

• Measuring AC/DC Voltage: Connect black test lead to the COM terminal and the red test lead to the terminal. Set the function switch to the V position for DC, V for AC.Connect the test leads across the source or circuit to be tested. Read the reading on the display. The polarity of the red test lead connection will be indicated as well.
  Note : To avoid electric shock or damage to the meter, do not apply a voltage higher than 600V between terminals.

• Measuring DC Current: Set the function switch to the A position.If the display does not read zero, press the button for zeroing.Press the trigger and clamp the jaws around the conductor to be tested. Make sure that the jaws are perfectly closed.
