  • Page 2: Safety Information

    Safety Information This manual contains information that must be followed for operating the meter safely and maintaining the meter in a safe operating condition. If this meter is not used in the manner specified, the protection provided may be impaired. Warning! Warns of potential danger, refer to the instruction manual to avoid personal injury or damage to the meter.
  • Page 3 Replace damaged leads with identical model or specification before using the meter. Where applicable use GS38 approved leads (not supplied) these are available from Di-Log. When using test leads keep fingers behind the finger guards. Do not apply more than the rated voltage, as marked on the meter between the terminals or between any terminal and ground.
  • Page 4 Safety Information Before making a measurement ensure that the rotary switch is set to the appropriate range. Do not turn the rotary switch whilst making a measurement. Use the appropriate terminals, function and range for your measurements. If the value to be measured is not known use the maximum measurement position and reduce the range step by step until a satisfactory reading is obtained.
  • Page 5 Safety Information Replace the battery as soon as the low battery indicator appears. If the battery is low the meter may give false readings. Turn the meter power off when not in use,. Remove the battery if the meter is in use for a long period. Constantly check the battery as it may have leaked.

  • Page 13: Operation

    Operation Warning: RISK OF ELECTROCUTION. HIGH-VOLTAGE CIRCUITS, BOTH AC AND DC, ARE VERY DANGEROUS AND SHOULD BE MEASURED WITH GREAT CARE. 1. ALWAYS turn the function switch to the OFF position when the meter is not in use. This meter has Auto OFF that automatically shuts the meter OFF if 15 minutes elapse between uses.
  • Page 14 Operation Range Button When the meter is first turned on, it automatically goes into AutoRanging. This automatically selects the best range for the measurements being made and is generally the best mode for most measurements. For measurement situations requiring that a range be manually selected, perform the following: 1. P ress the RANGE button. The “AUTO” display indicator will turn off. 2. P ress the RANGE button to step through the available ranges until you select the range you want. 3. P ress and hold the RANGE button for 2 seconds to exit the ManualRanging mode and return to AutoRanging.(If backlight is turned on, please press BACKLIGHT button it will turn off). Data Hold Button The Data Hold function allows the meter to “freeze” a measurement for later reference. 1. P ress the DATA HOLD button to “freeze” the reading on the indicator. The indicator “HOLD” will be appear in the display. 2. P ress the DATA HOLD button to return to normal operation.
  • Page 15 Operation Relative Button The relative measurement feature allows you to make measurements relative to a stored reference value. A reference voltage, current, etc. can be stored and measurements made in comparison to that value. The displayed value is the difference between the reference value and the measured value. P erform any measurement as described in the 1. operating instructions. P ress the RELATIVE button to store the reading 2. in the display and the “REL” indicator will appear on the display. T he display will now indicate the difference be- 3. tween the stored value and the measured value. P ress the RELATIVE button to return to normal 4. operation.
