OLED for more display clarity
The U1273A, the latest addition to
U1270 series, comes with an OLED
display that has outstanding contrast
levels and high brightness levels. The
display also allows wider viewing
angles up to 160 degrees to ensure
that you get the right readings at the
first glance.
Get a better grip on your DMM
The U1270 series is shaped perfectly
to fit in your hand, with or without
gloves on. Its non-slip ergonomic
shape enables you to carry your DMM
and perform measurements on the go
easily. Additionally, the controls are
easy to operate due to the large knob
and buttons.
Improve productivity with
intelligent features
Designed for maximum efficiency
and productivity in industrial settings,
these DMMs offer convenient functions such as ZLOW to eliminate stray
voltages, Smart Ω to minimize false
readings due to leakage current and
Qik-V to determine existence of AC
and/or DC voltages.
Continuity detection in noisy and dark
places is made easy with the U1270
series’ loud beeper and Visual Alert
function that indicates continuity and
improves safety.
When it comes to Variable Frequency
Drive (VFD) troubleshooting, the
U1270 series has Low Pass Filter to
handle the job with ease.
Water and dust resistant
The series’ tightly sealed design
helps protect against water, dust and
damage. Each DMM is IP 54 certified
so that you can carry out test and
measurement with confidence, even
in harsh working conditions.
Key Functions
Low Impedance (ZLOW)
The U1272A and U1273A are dual
input impedance digital multimeters.
The DMM’s high input impedance
is preferred in most electrical
measurements because it would not
load the circuit under test. However,
to obtain accurate measurements
on circuits that may contain stray
voltages, the U1272A and U1273A’s
2 kΩ low impedance function comes
in handy. Stray voltages are usually
found in non-energized electrical
wiring adjacent to powered wires due
to capacitive or inductive coupling
between these wires. When a pair
of test leads is placed between the
open circuit and neutral conductor,
the circuit is then complete and forms
a voltage divider in conjunction with
the input impedance of the multimeter.
High input impedance multimeter is
sensitive enough to measure voltage coupled into the disconnected
conductor, thus giving an inaccurate
indication of a live conductor. The low
impedance function serves to eliminate false readings by dissipating the
stray voltages, thus improves safety
and measurement efficiency during
voltage.
Figure 1. U1272A helps you identify the presence of stray voltage on a disconnected wire running parallel with the wire
powering up the VFD to an industrial motor. The image on the right shows the U1272A in low impedance mode.

Key Functions
Low Pass Filter (LPF)
The U1270 series offers a 1 kHz LPF
or Low Pass Filter to provide accurate
Variable Frequency Drive (VFD) output
measurement. This function eliminates
high frequency noise and harmonics.
This ensures the efficiency of your
motor filter as well.
Figure 2. Comparison of voltage output from industrial motor VFD without and with Low Pass Filter functionality.
Smart Ω
The U1272A and U1273A provide an
additional 30 Ohm range for low resistance measurement. This Smart Ω
function is available for ranges of
30 Ohm to 300 kOhm. It enhances
measurement accuracy with offset
compensation by removing residual
DC voltages of up to 1000 mV induced
by ground current and thermal EMF.
This function also enables ‘live’
resistance measurement without
isolating the measurement circuit.
With this, you will be able to obtain
leakage current using the secondary
display.

1. The specifications above is specified after 60 minutes of warm-up time.
2. The accuracy does not include the tolerance of the thermocouple probe.
3. Do not allow the temperature sensor to contact a surface that is energized above 30 Vrms or 60 V DC. Such voltages pose a shock hazard.
4. Ensure that the ambient temperature is stable within ±1 ºC and that the Null function is used to reduce the test lead’s thermal effect and temperature
offset. Before using Null function, set the multimeter to measure temperature without ambient compensation (°C) and keep the thermocouple probe
as close to the multimeter as possible (avoid contact with any surface that has a different temperature from the ambient temperature).
5. When measuring temperature with respect to any temperature calibrator, try to set both the calibrator and multimeter with an external reference
(without internal ambient compensation). If both the calibrator and multimeter are set with internal reference (with internal ambient compensation),
some deviations may show between the readings of the calibrator and multimeter, due to differences in ambient compensation between the
calibrator and multimeter. Keeping the multimeter close to the output terminal of calibrator will help reduce the deviation.
6. The temperature calculation is specified according to the safety standards of EN/IEC-60548-1 and NIST175.

1. Overload protection: 1000 V; input signal is < 20,000,000 V × Hz (product of voltage and frequency).
2. The frequency measurement is susceptible to error when measuring low-voltage, low-frequency signals. Shielding inputs from external noise pickup is
critical for minimizing measurement errors. Turning on the low pass filter may help you to filter out the noise and achieve a stable reading.

3. Notes for duty cycle specifications:
• The accuracy for duty cycle and pulse width measurements is based on a 3 V square wave input to the DC 3 V range. For AC couplings, the duty
cycle range can be measured within the range of 10% to 90% for signal frequencies > 20 Hz.
• The range of the duty cycle is determined by the frequency of the signal: {10 μs × frequency × 100%} to {[1 – (10 μs × frequency)] × 100%}.
• The pulse width (positive or negative) must be > 10 μs. The range of the pulse width is determined by the frequency of the signal.

Perform data logging with multimeters – wirelessly!
Data logging is an important function for industrial users to capture data
streams or plotting trending graphs. These data and graphs are used for analysis
to identify intermittent behavior or detect drifts. Agilent Mobile Logger is the
free Android application software that logs data and provides trending graphs
from Agilent handheld digital multimeters. Agilent Mobile Logger offers an array

Perform up to three multimeter measurements at the same time
with Agilent Mobile Meter
Agilent Mobile Meter is a free Android application software that allows an
Android device to connect, control and perform up to 3 multimeter measurements. Without the need to be physically present at various points, users can
now extend their reach to two or three places. This solution allows you to make
measurements from a safe distance, eliminates the need to walk back-and-forth
between measure target and control points, and monitors multiple measurements simultaneously. Achieve higher work productivity when you use the
U1177A with your Agilent handheld digital multimeters.
