Back Light; Auto Power Off - C-LOGIC 5300 Manual De Instrucciones

3) The meter will enter the manual range mode after the
"REL" button is pressed. REL mode is not available
for Hz/Duty range because it is an automatic range.
4) Press the "REL" button again to cancel the relative
measurement function.
5) Pressing the "REL" button at the HOLD mode will
cancel the HOLD function. The actual measurement
value taken will be stored in the memory as reference
value. The readings displayed for measurements
taken afterwards will be the difference between the
input value and the reference value.
6) Press the "RANGE" , "SELECT' buttons or turning the
rotary selector to cancel the relative measurement
function and resume normal measurement. The REL
symbol on the display will disappear.
7) O L triggering: Under the REL mode, O L (over limit)
will flash on the display if the input value exceeds the
allowed val u e for that range. Press the "REL" button
again to cancel the relative measurement function.
The REL mode cannot be entered when O Lis flashing.

Note:
1) LEO, which requires a larger working current, is the
main so urce of back light. Although the meter is
equipped with a timer set at 1 O seconds (i.e. the back
light will be off automatically after 1 O seconds),
frequent use of the back light will shorten the life of
the batteries. Therefore, do not use the back light
unless necessary.
2) When the battery voltage is S3. 6V, the symbol "1: +I"
(battery low) will appear on the LC D. When the back
light is on, even if the batter is �3.6V, the "1: +I" may
appear beca use of its large working current which
will cause the voltage to drop. (The accuracy of the
measurement cannot be assured when the "1: + I "
symbol appears.) In this case, you need not replace
the batteries yet. Normally, the batteries can last
until the " 1: +I " appears when the back light is not
being used.

4.7 Auto Power Off

1) lf there is no any operation within any thirty minute
period after the power is on, the meter will enter the

"REL" b utton to resume operation of the meter under
auto the power off mode.
3) Press the "SELECT' button to disable the auto power
off function.
