Parameter can be switched consecutively. Measuring DC voltage 1 Set the rotary switch to or . Ensure that is shown on the display. 2 Connect the red and black test leads to input terminals V. mV (red) and COM (black) respectively. 3 Probe the test points and read the display. 4 Press to display dual measurements. Parameter can be switched consecutively. Performing Current Measurements Measuring AC current 1 Set the rotary switch to or . Press to ensure is shown on the display. 2 Connect the red and black test leads to input terminals µA.mA (red) and COM (black) or A (red) and COM (black) respectively. 3 Probe the test points in series with the circuit and read the display. Measuring DC current 1 Set the rotary switch to . Ensure that shown on the display. or is 2 Connect the red and black test leads to input terminals µA.mA (red) and COM (black) or A (red) and COM (black) respectively. 3 Probe the test points in series with the circuit and read the display. CAUTION · If the current is 440 mA, connect the red and black test leads to input terminals µA.mA (red) and COM (black). · If the current is > 440 mA, connect the red and black test leads to input terminals A (red) and COM (black). U1253A Quick Start Guide https://manual-hub.com/ Performing Resistance, Conductance, and Continuity Measurements 1 Set the rotary switch to . 2 Connect the red and black test leads to input terminals (red) and COM (black) respectively. 3 Probe the test points (by shunting the resistor) and read the display. 4 Press to scroll through audible continuity ( / ), conductance ( ), and resistance tests ( , , or ) as shown. Audible continuity PRESS SHIFT PRESS SHIFT Performing Capacitance and Temperature Measurements Capacitance 1 Set the rotary switch to . 2 Connect the red and black test leads to input terminals (red) and COM (black) respectively. 3 Connect the red test lead to the positive terminal of the capacitor, and the black test lead to the negative terminal. 4 Read the display. Temperature 1 Set the rotary switch to . Press to select temperature measurement. 2 Connect the red and black test leads to input terminals (red) and COM (black) respectively. 3 Plug the thermocouple adapter (with the thermocouple probe connected to it) into input terminals TEMP (red) and COM (black). 4 Touch the measurement surface with the thermocouple probe. 5 Read the display. https://manual-hub.com/ U1253A Quick Start Guide Frequency and Frequency Counter Measurements Frequency Measurement During AC/DC voltage or AC/DC current measurements, you can measure the signal frequency by pressing at any time. Frequency Counter Measurement 1 Set the rotary switch to . 2 Press to select the frequency counter ( ) function. The default input signal frequency is divided by 1. This allows signals up to a maximum frequency of 985 kHz to be measured. 3 Connect the red and black test leads to input terminals V (red) and COM (black) respectively. 4 Probe the test points and read the display. 5 If the reading is unstable or zero, press to select division of input signal frequency by 100 ( will be shown on the display). This accommodates a higher frequency range of up to 20 MHz. 6 The signal is out of the U1253A frequency measurement range of 20 MHz if the reading is still unstable after Step 5. WARNING Use the frequency counter for low voltage applications. Never use the frequency counter on AC power line systems. Square Wave Output 1 Turn the rotary switch to . 2 Press to select duty cycle (%) on the primary display. 3 The default square wave frequency is 600 Hz as shown by the secondary display, with a 50% duty cycle as shown by the primary display. 4 Press or to scroll through the available frequencies (there are 28 frequencies to choose from). 5 Press or to adjust the duty cycle. The duty cycle can be set from 0.390625% to 99.609375%, in steps of 0.390625%. The displayed duty cycle has a resolution of 0.001%.

CAUTION · Do not rotate the rotary switch from position when charging the battery. · Perform battery charging only with 7.2 V or 8.4 V NiMH rechargeable battery, 9 V size. · Disconnect test leads from all the terminals when charging the battery. · Ensure proper insertion of battery in the multimeter, and follow the correct polarity. · A new rechargeable battery comes in a discharged condition and must be charged before use (refer to the U1253A User's and Service Guide for charging instructions). Upon initial use (or after a prolonged storage period) the rechargeable battery may require three to four charge/discharge cycles before achieving maximum capacity. To discharge, simply run the multimeter under the rechargeable battery's power until it shuts down or low battery warning appears. · The multimeter may indicate that charging is complete after a few ten minutes when charging a new rechargeable battery. This is a normal phenomenon with rechargeable batteries. Remove the rechargeable battery from the device, reinsert it and repeat the charging procedure.
