UEi Test Instruments DL49 - Manual (Page 3)

LCD Display Functional Description
1. Peak Hold: I n d i cates the meter is displaying the maximum inductive
AC current value recorded.
2. Continuity: I n d i cates the meter is in the continuity measurement
mode and will sound a tone when measuring resistance below
approximately 50 ohms.
3. Data Hold: I n d i cates the value displayed is held on screen
(the data hold button is pressed).
4. Low Battery Indicator: This symbol appears when the battery
needs replacement.
NOTE: A low battery will adversely affect accuracy.
5. AC: I n d i cates that alternating current/voltage is being measured.
6. Minus: I n d i cates the value measured has a negative polarity.
7. DC: I n d i cates that direct current/voltage is being measured.
8. mVA: I n d i cates that millivolts (mV), volts (V), milliamps (mA) or
amps (A) is being displayed.
9. MKΩ: Indicates that Megohms, Kilohms, or ohms are
being displayed.
10. Numerical Value: Displays the total value of the units displayed.
Operating Instructions
Auto-Power Off
This instrument automatically shuts off after 30 minutes of inactivity. The
meter is considered active when there is a change of at least 10 digits
during this period (for example: the meter senses a change from 24.04
volts to 24.14 volts).
Autorange Resolution
This instrument automatically selects the range that gives you the best
resolution for the function and value measured. As the meter seeks the
appropriate range, the display may briefly display an overload (OFL)
indication or show quickly changing values until it stabilizes.
4. Data Hold Push-button: Freezes the value displayed on the
digital read-out.
5. Peak Hold Push-button: Used to capture the highest AC
inductive amp reading and to automatically zero (approximately) the
inductive DC amp readings.
6. Clamp Lever: Opens and closes current clamp jaw.
7. Rotary Function Switch: Used to power the meter on and off, or
to select one of the available measurement functions.
NOTE: Measure inductive AC and DC current using the clamp.
Measure volts AC and DC, resistance and continuity at the
test lead inputs.
8. Off Position: Turns the meter off. Always store your meter in the
off position. If the meter will not be used for a month or more,
remove the batteries.
9. Display: C o m m u n i cates function, range, and value information to
the user.
10. Common Terminal: The black test lead is plugged into this
terminal to supply the ground or “low” reference for
all measurements.
11. Volt/Ohm (Ω) Terminal: The red lead is plugged into this
terminal. It is used for AC/DC volts, ohms, and continuity measurements.
12. Maximum Input Statements: M AX 600V indicates that a
m aximum of 600 Volts can be applied between the two terminals of
b e tween earth ground and any terminal.
