USAG 075 E Manual De Instruccion página 13

• When measuring voltage, do not input the limited voltage over 1000V DC or
750V AC RMS.
• The voltage below 40V is safety, when measuring voltage over 60V DC or 40V
AC, check whether the test leads are connected correctly, whether the insulation
is good, to avoid electric shot.
• When changing function and range, the testing leads should be removed from
the testing points.
• Select correct function and range.
• When measuring current, do not input current over 10A.
• Do not connect to a voltage over 1000V DC or 700V AC RMS.
• Do not measure voltage at Ampére - Ω - Capacity - Diode and Continuity test
and temperature range.
• Do not operate the instrument before fixing the rear case or finishing replacing
battery.
Maintenance
• Do not try to modify the circuit.
• Before replacing battery or fuse, remove the testing leads from testing point
and turn the power off.
• Do not operate the instrument when the battery is not fitted or the rear is not
fixed.
• Clean the meter with a damp cloth and soft detergent, do not use abrasive and

it again, "H" symbol disappears and quits the mode.
"REL" key
Press it, reading will be zero, the instrument is in relative measuring
mode and display "REL" symbol. Press it again will quite the mode.
"RANGE" key
To select auto range or manual range mode. The meter is in auto range
mode originally, LCD displays "AUTO", press it can transfer to manuol
range. One range increase with each pressing and cycle from lower
range to higher range. Press it down for more than two seconds, will
return to auto range mode.
"DC/AC" key
Up for DC and down for AC and "AC" display on LCD.
"Hz/DUTY" key
When measuring DCV/ACV (current), press the key can switch
frequency/duty-cycle/voltage (current), when measuring frequency,
press the key can switch frequency/duty-cycle (1-99%).
