LCD Display Functional Description
1. Indicates that the audible continuity mode has been selected.
2. Indicates that diode testing has been selected.
3. Indicates the meter is reading DC voltage or current.
4. Indicates a negative polarity measurement. (Applicable to
DC functions).
5. Indicates the meter is reading AC voltage or current.
6. Indicates that HOLD has been selected and the display is no
longer updating numerical data.
7. Indicates MAX push-button is pressed and the meter is
displaying the maximum numerical value recorded in any mode
from the time the button was pressed.
8. The following symbols represent the type and value of
measurement being made.
9. I n d i cates the battery is low and must be changed immediately
10. Indicates measured numerical values
NOTE: When OL is displayed on the LCD, it indicates the value
measured exceeds the limits of the selected range, or exceeds the
over-all limits of the meter.
6. 10 Amp, Fused, Meter Lead Terminal: Use this input
terminal (port) when measuring amps greater than 400 mA,
but less than 10 Amps AC or DC. Use caution when selecting
a m p e rage measurements on the rotary dial. Remember
a m p e rage measurements are made in series with your circuit.
7. This Symbol Reminds the User to Follow Provided
Instructions: See “Caution” in the international symbol section
of this manual.
8. Microamp/Milliamp Input Terminal: The red test lead is
plugged into this terminal when measuring current (AC or DC)
in the 400 mA and below ra n g e .
9. Common Terminal: The black test lead is plugged into this
terminal, and supplies the ground or “low” reference for all
m e a s u r e m e n t s .
10. "Flash" Symbol: Warns operators that potentially dangerous
voltages may be present. Use caution when making
high-voltage measurements.
11. Multifunctional Terminal Information: I n d i cates the
m aximum input values and ca t e g o ry ratings established
by IEC 1010 - 1.
12. Multifunctional (Volts, Ohms, and Diode Test) Input
Terminal: Use the red test lead in this terminal for any of these
test functions.
