The display also allows wider viewing angles up to 160 For wireless connectivity to smartphones and tablets, the U1270 Series is compatible with the U1177A infrared-to-Bluetooth adapter for maximum efficiency and productivity in completing measurements tasks. Adding the optional U1177A to a U1270 Series you can easily perform remote monitoring and data logging via Android devices or Windows(R)-based PC. Key Functions Water and dust resistance (IP54) The series' tightly sealed design helps protect against water, dust and damage. Each handheld DMM is certified with IP 54 ratings so that you can carry out tests and measurements with confidence, even in harsh working conditions. Operational up to 3000 meters altitude For high altitude applications such as wind farm maintenance, you can measure with confidence using the U1270 Series, capable of measuring up to 3000 meters above sea level. High measurement rate at seven readings per second for Voltage and Current Up to 10,000 recording points for manual, auto and event logging You can detect even the slightest change in your sensitive signals (Voltage and Current) with its high measurement rate capability. By clicking the resettable smooth function button, you may customize the readings' sensitivity suitable for various tests. Record measurements on-the-go and transfer data to PC conveniently with the huge internal memory of up to 10,000 recording points. The GUI Data Logging software and optional U1173A IR-USB cable are required to transfer data or perform real time data logging on a PC. Visual alert for continuity test (for U1271A and U1272A only) Built-in Low Pass Filter Continuity detection in noisy and dark environments is made easy with U1270 Series' loud beeper and flashing backlight that indicates continuity and thus improves safety. The U1270 Series offers a 1 kHz LPF or Low Pass Filter to provide accurate Variable Frequency Drive (VFD) output measurements. This function eliminates high frequency noise and harmonics, ensuring motor filter efficiency. Figure 1. Comparison of voltage output from industrial motor VFD without and with Low Pass Filter functionality. 2 Key Functions Low impedance mode Peak detect at 250 s Stray voltages are usually found in non-energized electrical wiring adjacent to powered wires due to capacitive or inductive coupling between these wires. The low impedance mode serves to eliminate false readings by dissipating these stray voltages thus improves safety and measurement efficiency during voltage measurement. The peak detect function allows you to capture the engine or motor startup transient as fast as 250 s. Figure 2. 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. 3 Front and Back Panel Description OLED display with 2000:1 contrast ratio and 160 degree viewing angle 30,000 counts resolution Peak detect records transients as fast as 250 s Smart 1 removes residual voltage of up to 1000 mV Measure up to 1000 V AC and DC Auto diode 1 automatically determines diode polarity Low Pass Filter (LPF) removes unwanted high frequency signals Temperature measurement: J type thermocouple -210 to 1200 C 1, K type thermocouple -200 to 1732 C ZLOW 1 provides both high and low impedance modes to eliminate stray voltages Measure up to 10 A (20 A for 30 s) Front panel 1.

Add 0.3% to the specified accuracy when measuring signals > 10 to 20 A for 30 seconds maximum. After measuring currents > 10 A, cool down the multimeter for twice the duration of the measured time before proceeding with low current measurements. * U1273AX only: The accuracy for the 300 A range, 3000 A range, and 30 mA is specified after the Null function is used when measuring at temperatures below -20 C. The Null function is used to subtract the test lead resistance and thermal effect (by shorting the test leads). * U1273AX only: For all AC+DC current ranges, the accuracy is specified at 2.5% + 30 counts when measuring below -20 C for 20 to 45 Hz AC+DC signals. 13 Electrical Specifications Temperature specifications1 - 6 Thermocouple type K J Accuracy (% of reading + as specified below) U1271A U1272A U1273A/U1273AX Range Resolution -200 to 1372 C 0.1 C 1% of reading + 1 C 1% of reading + 1 C 1% of reading + 1 C -328 to 2502 F 0.1 F 1% of reading + 1.8 F 1% of reading + 1.8 F 1% of reading + 1.8 F -210 to 1200 C 0.1 C -- 1% of reading + 1 C 1% of reading + 1 C -346 to 2192 F 0.1 F 1% of reading + 1.8 F 1% of reading + 1.8 F -- 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 C 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.

Overload protection: 1000 V; input signal is < 20,000,000 V x 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. Duty Cycle3 Mode Range Accuracy at full scale DC coupling 99.99% 0.3 % per kHz + 0.3 % AC coupling 99.99% 0.3 % per kHz + 0.3 % 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 s x frequency x 100%} to {[1 - (10 s x frequency)] x 100%}. * The pulse width (positive or negative) must be > 10 s. The range of the pulse width is determined by the frequency of the signal.
