Diode Test
Range Introduction Remark
2V
The approximate forward voltage
drop of the diode will be displayed.
If the voltage drop is more than 2V,
the display shows the overrange
indicator "OL"
Open Circuit
Voltage:
about 3V
Short Circuit
Current:
< 0.9mA
Continuity Test
Range Introduction Remark
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
Open Circuit
Voltage: about
0.45V
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 stores
the present reading as a reference for subsequent measurements,
and " " appears as an indicator. The 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 only in 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, "AUTORANGE" is displayed.
1. Press the RANGE button to enter the manual range mode, the
symbol "AUTORANGE" 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 "AUTORANGE" 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.
