Introducing the Agilent U1251A and U1252A Handheld Digital Multimeter
The handheld digital multimeters’ key features are:
• DC, AC and AC + DC (only U1252A) voltage and current
measurements.
• True- RMS measurement for both AC voltage and current
• Rechargeable Ni- MH battery with built- in charging
capability (only U1252A)
• Ambient temperature on second display
• Battery capacity indicator
• Blue LED backlight
• Resistance measurement up to 50M
(for U1251A) and
500M
(for U1252A)
• Conductance measurement from 0.01nS (100G
) ~ 50nS
• Capacitance measurement up to 100mF
• Frequency counter up to 20MHz (only U1252A)
• The % scale readout for 4- 20mA or 0- 20mA measurement
• dBm with selectable reference impedance
• 1ms Peak Hold to catch inrush voltage and current easily
• Temperature test with selectable 0
°C compensation
(without ambient temperature compensation).
• K- type (for U1251A) and J/K- types temperature
measurement (for U1252A)
• Frequency, duty cycle and pulse width measurements
• Dynamic Recording for min, max and average readings
• Data Hold with manual or auto trigger and Null mode
• Diode and audible continuity tests
• Square wave generator with selectable frequency, pulse
width and duty cycle (only U1252A)
• Agilent GUI Application Software (IR- USB cable sold
separately)
• Closed case calibration
