Introducing the Agilent U1253B True RMS OLED Multimeter
The key features of the true RMS OLED multimeter are:
• DC, AC, and AC+DC voltage and current measurements.
• True RMS measurement for both AC voltage and current.
• Rechargeable Ni- MH battery with built- in charging
capability.
• Ambient temperature readout that accompanies most
measurement readouts (both in single and dual display
modes).
• Battery capacity indicator.
• Bright orange OLED (Organic Light Emitting Diode)
display.
• Resistance measurement up to 500 MΩ.
• Conductance measurement from 0.01 nS (100 GΩ) to
500 nS.
• Capacitance measurement up to 100 mF.
• Frequency counter up to 20 MHz.
• Percentage scale readout for 4 mA to 20 mA, or 0 mA to
20 mA measurement.
• Measurement of dBm with selectable reference impedance.
• 1 ms peak hold to catch in- rush voltage and current
easily.
• Temperature test with selectable 0
°C compensation
(without ambient temperature compensation).
• J- type or K- type probe for temperature measurement.
• Frequency, duty cycle, and pulse width measurements.
• Dynamic recording for minimum, maximum, average, and
present readings.
• Data hold with manual or auto trigger and relative modes.
• Diode and audible continuity tests.
• Square wave generator with selectable frequency,
pulse width, and duty cycle.
