SPECIAL PANEL MARKINGS:

We have placed the following special markings on the panel to remind you
of the measurement limitations and safety.

20A MAX FUSED         The maximum current that you can measure at this
                      terminal is 20 amps DC/AC.  This terminal is fuse
                      protected.  For your safety during continuous
                      measurements, keep the duty cycle as 30 seconds in
                      use and 15 minutes in rest.

200 mA MAX FUSED      The maximum current that you can measure at this
                      terminal is 200 mA DC/AC. This terminal is limited
                      to 2 amps by a fuse.

500V MAX              To avoid electrical shock or instrument damage, do
                      not connect the common input terminal (COM) to any
                      source of more than 500 V with respect to
                      earth/ground.

MAX 750V AC 1000V DC  The maximum voltage this meter can measure is
                      1000V DC or 750V AC.

Be extra careful when making high-voltage measurements. DO NOT TOUCH THE
TERMINALS OR PROBE ENDS.

SAMPLING RATE: ................................................ Variable

Note:  Sampling rate is defined by software.

Refer to the complete operating instructions.

Specifications are typical; individual units might vary.  Specifications
are subject to change and improvement without notice.
