Diode Test
Range Introduction
The approximate forward voltage drop of the diode
2V will be displayed. If the voltage drop is more than
2V, the display shows the overrange indicator "OL"
Continuity Test
Range Introduction
The built-in buzzer will sound if the resistance is less
than about 30Ω. The buzzer will not sound if the
resistance is more than 150Ω
OPERATION INSTRUCTION
Using Relative Mode
Selecting Relative mode causes the meter to store the present reading as a reference for
subsequent measurements and zero the display.
1. Press the REL button, the meter enters the Relative mode and store the present reading
as a reference for subsequent measurements, and "
display reads zero.
2. When you perform a new measurement, the display shows the difference between the
reference and the new measurement.
3. Press the REL button again, the meter exits the Relative mode.
Note: Relative mode is available onlyin voltage, current, capacitance and resistance
measurements.
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 Range" is displayed.
1. Press the RANGE button to enter the manual range mode, the symbol "Auto Range"
disappears. 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 about
2 seconds. The meter returns to the autorange mode and "Auto Range" is displayed.
Data Hold Mode
Press the HOLD button to hold the present reading on the display, the symbol "
will appear on the display as an indicator. To exit the Data Hold mode, just press the button
again. " " disappears.
Built-In Buzzer
1. When you press a button, the built-in buzzer will sound a beep if the press is effective.
2. The buzzer will sound several short beeps about one minute before the meter turns off
automatically and sound long beep before the meter turns off automatically.
3. The buzzer will sound and the displaywill show "OL" in one of the following conditions:
a. The AC voltage under measurement is more than about 600V ac when the meter is in
the highest AC voltage range.
