Introducing the Agilent U1251B and U1252B Handheld Digital Multimeter
The handheld digital multimeter’s key features are:
• DC, AC and AC + DC (only U1252B) voltage and current
measurements.
• True- RMS measurement for both AC voltage and current
• Rechargeable Ni- MH battery with built- in charging
capability (only for U1252B)
• Ambient temperature on second display
• Battery capacity indicator
• Bright orange LED backlight
• Resistance measurement up to 50 M
(for U1251B) and
500 M
(for U1252B)
• Conductance measurement from 0.01 nS (100 G
) ~ 50 nS
• Capacitance measurement up to 100 mF
• Frequency counter up to 20 MHz (only U1252B)
• The % scale readout for 4- 20 mA or 0- 20 mA measurement
• dBm with selectable reference impedance
• 1 ms Peak Hold to catch inrush voltage and current easily
• Temperature test with selectable 0
°C compensation
(without ambient temperature compensation).
• K- type (for U1251B) and J/K- types temperature
measurement (for U1252B)
• 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 U1252B)
