Measuring Voltage - Facom 715 Manuel D'utilisation

OPERATION INTRODUCTION
Using Relative Mode
Selecting relative mode causes the meter to store the present reading as a reference for subsequent measurements.
1. Press the "REL" button. The meter enters the Relative mode and stores the present reading as a reference for subsequent
measurements, and "REL" appears on the display as an indicator. The display reads zero.
2. The display shows the difference between the reference and a new measurement.
Tip: Press the "REL" button again. "REL" flickers on the display, and the display shows the reference. Press the "REL" button once
more, the meter will return to Relative mode.
3. Press and hold down the "REL" button for more than 1 second, the meter exits the Relative mode.
Data Hold Mode
After pressing the "HOLD" button, the present reading is held on the display, meanwhile "
" is displayed on the display as an
indicator. To exit the Hold mode, press the button again and the indicator " " will disappear.
MIN MAX Recording Mode
The MIN MAX mode records minimum and maximum values of all input values since this mode is activated.
When the inputs go below the recorded minimum value or above the recorded maximum value, the meter records the new value.
To use MIN MAX recording :
1. Make sure the meter is in the desired function and range.
2. Press the "MAX/MIN" button to activate the MIN MAX mode and the display shows the maximum reading, meanwhile "MAX"
appears on the display as an indicator.
3. Press the "MAX/MIN" button to step through the minimum reading ("MIN" appears), the present reading ("MAX" and "MIN"
flicker), and the maximum reading ("MAX" appears), and so on.
4. To exit and erase stored readings, press and hold down the "MAX/MIN" button for more than 1 second or turn the range switch.
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.
1. To enter the manual range mode, press the "RANGE" button. The meter enters the manual range mode, "AUTO" turns off, "MANU"
turns on. Each press of the "RANGE" button increases the range. When the highest range is reached, the meter wraps to the lowest
range.
2. To exit the manual range mode, press and hold down the "RANGE" button for more than 2 seconds, the meter returns to the
autorange mode.

Measuring Voltage

1. Connect the black test lead to the "COM" jack and the red test lead to the " " jack.
2. Set the range switch to the desired or range ( The range is for dc voltage measurements, the range is for ac
voltage measurements ).
3. If you use manual range mode and don't know the magnitude of the voltage to be measured beforehand, select the highest range
and then reduce it range by range until satisfactory resolution is obtained.
4. Connect the test leads across the load to be measured.
5. Read LCD display. For dc voltage measurements, the polarity of the red lead connection will be indicated as well.
Note : To avoid electric shock to you or damages to the meter, do not attempt to measure dc voltage higher than 600V or ac voltage
higher than 600V rms although readings may be obtained.
