4.4 Max/Min Measurement Choice
1) Press "MAX/MIN" key to enter MAX mode, and always keep measurement maximun value; press
"MAX/MIN" key again, the meter will enter minimun value measurement state; press "MAX/MIN"
key for the third time, the meter will display the difference of maximun and minimun value; press
"MAX/MIN" key to repeat the above operations by recicling.
2) After entering MAX or MIN mode, it will automatically save the measured maximum or minimum
value.
3) If the user presses "MAX/MIN" key more than 2 sec, the meter will restore normal measuring
range.
Note:
1) For using the maximum/minimum value measurement mode, the manual range mode must be
active.
2) When the meter is in the frequency, duty ratio measurement state, it can't switch to maximum/
minimum value measurement mode.

4.5 Function Switch

1) In the resistance mode, press "FUNC" button, it will switch among resistance, diode and
continuity detection by recycling.
2) In the Voltage or Ampere mode, press "FUNC" button to change AC/DC.
3) In temperature mode, press "FUNC" key to cahnge the temperature unit ºC/ºF.
4.6 REL Measurement
1) REL button is relative value Measurement button. The current display value can be stored in the
memory as reference value. When the user measures later, the display value is the difference
for input value minus reference value. ie. RELΔ(current reading)= Input value - Reference value.
2) At DCA mode, the REL key function will be replace by "ZERO" function.
4.7 Back Light And Clamp Head Light
1) In the process of measurement, if ambient light is too dark to read, press "B.L/HOLD" key for two
seconds to turn on the display backlight and the clamp head light. Both lights will automatically
turn off after about 30 seconds.
2) During this period, pressing "B.L/ HOLD" key for two seconds will turn off the display backlight
and the clamp head light.
Note:
When battery voltage ≤ 3.6V, the LCD displays
backlight, the battery voltage drops below 3.6V, due to high working current. The " " symbol may
"
appear, and Measurement accuracy is not guaranteed. Continue to use the meter normally without
using backlight. Do not replace the battery until "

4.8 Automatic Power-Off

1) If there is no operation during any 30 minutes after turning the machine on, the meter will enter
suspended stated, automatically powering off to save the battery.
