Información
The Multimeters are portable bench-type Digital multimeter (DMMs) with 3-1/2 digit liquid crystal displays (LCDs). The
Multimeters have the following industry-standard features:
• Voltage measurements from 100 μV to 1000V dc and 10 mV to
750V true-rms ac.
• Current measurements from 100 nA to 2 A dc and 10 μΑ to 2A
true-rms ac (up to 10A for the 8012A • Resistance measurements from 100 mH (1 mH for the 8012A to 20 ΜΩ.
The Multimeters also have the following special measurement
features:
• Conductance measurements up to 10,000 ΜΩ of equivalent
resistance.
• Resistance ranges that supply enough voltage to turn on a
PN junction for testing diodes and transistors.
indication.
Protection from overloads and transients up to 6 kV for 10
microseconds.
Dual-slope integration a/d conversion to ensure noise-free
measurements.
Long term calibration stability (1 year).
