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 func-

tions such as Z

LOW

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.
PAGE 3
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.
