4.6 Back light and clamp lighting bulb
•
Press the
”HOLD/B.L”
button for two or more seconds to switch on the back
light if the light in the environment is too dim for taking reading, which will
last for 15 seconds.
•
During the back light is working, press the “HOLD/B.L” button for two or
more seconds, it will be turned off.
•
At the current range, when the back light is switched on, the clamp lighting
bulb will be turned on at the same time.
NOTE:
• LED which requires a larger working current, is the main source of back light.
Although the meter is equipped with a timer set at about 15 seconds (i.e. the
back light will be off automatically after about 15 seconds), frequent use of
the back light will shorten the life of the batteries. Therefore, do not use the
back light unless necessary.
• When the battery voltage is ≤3.7V, the symbol “
” low will appear on the
LCD.
• When the back light is on, even if the batter is ≥3.7V, the “
” may appear
because of its large working current which will cause the voltage to drop.
(The accuracy of the measurement cannot be assured when the “
“). may
appear because of its large working current which will cause the voltage to
drop. (The accuracy of the measurement cannot be assured when the “
”
appears when the back light is not being used.
4.7 Auto power off
•
If the mode switch or keys of the meter is no action within 15 minutes, the
system will power off automatically (sleep mode). In Auto Power-off status,
press any key, the meter will “Auto Power-On” (Operation Mode)
4.8 Preparating for measurement
•
Switch on the power by turning the rotary selector. If the battery voltage is
lower than 3.7V, the “
” symbol will appear and the batteries should be
replaced.
•
The “
” symbol shows that the input voltage or current should not exceed
the specified value in order to protect the internal circuit from damage.
• Turn the rotary selector to the required function and range to be measured.
