Opis: BENCH/PORTABLE 4 1/2 DIGIT DIGITAL MULTIMETER
Informacje:
                                    Data Precision Mode! 2480/2480R Digital Multimeter is a AVi
digit, laboratory quality, portable as well as bench-useful,
multimeter, incorporating 25 Measuring Function/Range
capabilities. These include:

DCV, ACV, DCmA, ACmA, and KOhms, Resolutions of 10 microvolts,

0.1 ohms, and 10 nanoamperes are obtained at the lowest
selectable full scale range, whiie voltages up to 1200VDC or
1400 peak AC and currents up to 2 amperes may be measured by
Model 2480/2480R with 4V2 digit resolution and specified
accuracies. All values are direct reading with automatically
positioned décimai point and polarity sign (fordc
measurements only),

b.	Model 2480 measures ac inputs with average sensing
calibrated for RMS, whiie Mode! 2480R measures ac inputs
with true RMS values. All other measuring functions are
performed In the same manner in Mode! 2480 or Mode! 2480R.

c.	Information in this manual is organized so that operators
and system users may locate applicable data and instructions
(through Chapter 3) without having to wade-through technical
detail necessary for maintenance and repair. Information in
Chapters 4 and 5 essentially support the technical
requirements for maintenance, trouble-shooting, and repair
activities.

d.	The basic Model 2480/2480R is complete with integral
battery charger, detachable line cord, and test probes.
Optional battery pack assembly may be installed in the field
at any time.
