The relative measurement value reflects the changes of the measured value. It also can be used to take off the errors
brought about by lead resistance or distributed capacitance during measuring low resistance and low capacitance.
● Maximum/minimum value measurement: by pressing MAX/MIN keys the meter can enter the maximum/minimum value
record state, and it will continuously update the maximum/minimum values based on the new measurement results.
● Auto power off: The meter will automatically turn off after fifteen minutes , unless pressing any key or changed the rotary
switch . And in this case , the energy consumption still exist , but is very little . if the meter is restarted by pressing any key ,
except HOLD , the last metrical data will be displayed on the LCD and changing the rotary switch can also restart the
meter , but the last number will be cleared away. If the PC-LINK is in the work , the AUTO POWER OFF will not be
happened and the meter will be operated continuously
● Low voltage detection: when the meter detecting the total voltage of the batteries lower than 7V, the
LCD screen will be lighted to prompt the batteries should be replaced.
● Analog indication bar: analog indication bar is used for graphic measurement value and it always synchronizes with the
size of the present measured value. During the maximum value/minimum value measurement and the relative value
measurement it sill synchronizes with the size of the present measured value, and not indicating the maximum
value/minimum value or the relative value.
● PC-LINK: press down the PC-LINK key, the meter will open the infrared interface for sending the measured data and
status to the computer. Equipped with record and graphic software (options) the meter can display, record and describe the
measured electric quantity on computer. As the data transmission between the meter and computer is depending on light
coupling, so measurement of high voltage will not affect the safety of computer.
