Analogue
Bar Graph
Provides an analog indication of the present input, quick response.
Analogue Bar Graph
The bar graph provides an analogue indication of the measured input. For most measurement functions, the bar graph updates 10 times per second.
Using MAX MIN
The MAX MIN mode stores minimum (MIN) and maximum (MAX) input values. When the input goes below the stored minimum value or above the stored maximum value, the
Meter beeps and stores the new value.
Press MAX MIN to enter MAX MIN mode. The sampling time is every 2 seconds. The maximum reading and MAX are shown on the left secondary display. The minimum
reading and MIN are shown on the right secondary display. The primary display shows the present measurement reading.
Press MAX MIN the second time, the present measurement reading is shown on the left secondary display. The minimum reading and MIN are shown on the right secondary
display. The primary display shows the maximum value.
Press MAX MIN the third time, the present measurement reading is shown on the left secondary display. The maximum reading and MAX are shown on the right secondary
display. The primary display shows the maximum value.
Each subsequent press of MAX MIN steps through the above three modes.
To exit MAX MIN mode, press EXIT . Also, press HOLD could stop the Meter updating reading.
MAX MIN mode can only be used under MANUAL ranging mode.
