3.Safety Instructions
This meter has been designed for safe use, but must be operated with caution.
The rules listed below must be carefully followed for safe operation.
3-1.NEVER apply voltage or current to the meter that exceeds the specified maximum:
Input Protection Limits
Function
V DC or V AC
mA AC/DC
A AC/DC
Frequency, Resistance, Capacitance,
Duty Cycle, Diode Test, Continuity
Temperature
Surge Protection: 8kV peak per IEC 61010
3-2.USE EXTREME CAUTION when working with high voltages.
3-3.DO NOT measure voltage if the voltage on the "COM" input jack exceeds 1000V above
earth ground.
3-4.NEVER connect the meter leads across a voltage source while the function switch is
in the current, resistance, or diode mode. Doing so can damage the meter.
3-5.ALWAYS discharge filter capacitors in power supplies and disconnect the power when
making resistance or diode tests.
3-6.ALWAYS turn off the power and disconnect the test leads before opening the covers to
replace the fuse or batteries.

4.Feature
4-1.Understanding the Push Buttons
The 12 push buttons on the front of the Meter activate features that
augment the function selected using the rotary switch, navigate
menus or control power to Meter circuits.
F1F2F3F4 Selects sub-functions and modes related to the rotary switch function.
Cursor buttons select an item in a menu, adjust display contrast, scroll through information,
and perform data entry.
HOLD Freezes the present reading in the display and allows the display to be saved. Also
accesses AutoHold.
RANGES switches the Meter range mode to manual and then cycles through all ranges. To return
to auto ranging, press the button for 1 second.
MAX/MIN Starts and stops MIN MAX recording.
