The device measures DC and AC voltage up to 1000 V, DC and AC current up to 10 A, as well as temperature in the range from -55\u00b0C to 500\u00b0C. It maintains high precision and practicality, making it ideal for everyday use.<\/p>\n<p>\n<img decoding=\"async\" alt=\"A hand wearing a red protective glove holds a UNI-T digital multimeter, measuring electrical parameters in a control cabinet.\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/20912\/27764\/4.jpg\" \/>\n<\/p>\n<h3>Practical features for service work<\/h3>\n<p>The model features a display with a maximum reading of 6000, as well as continuity test, Data Hold, relative mode, and adjustable backlight functions. Compared to other models in the series, it stands out with a dedicated LED diode test function, though it does not include a MAX\/MIN mode. Automatic and manual range switching, auto-off, and intuitive operation ensure ease of use across various applications.<\/p>\n<p>\n<img decoding=\"async\" alt=\"A hand in a red glove holding a UNI-T multimeter displaying 49.77 Hz, positioned next to a motor and an inverter.\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/20912\/27764\/1.jpg\" \/>\n<\/p>\n<h3>Expanded capabilities and full safety<\/h3>\n<p>The multimeter comes with a Type K thermocouple, allowing the user to immediately utilize the temperature measurement function. Safety is ensured by a wrong-wire connection alarm and CAT III 600V overvoltage protection. This model is designed for users who expect greater functionality and want a tool that is also useful for testing LED lighting.<\/p>\n<p>\n<img decoding=\"async\" alt=\"Measuring a voltage of 1.76 V DC on an LED using probes and a UNI-T digital multimeter standing nearby.\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/20912\/27764\/3.jpg\" \/>\n<\/p>\n<h3>Included<\/h3>\n<ul class=\"list-disc pl-5\">\n<li>Digital multimeter<\/li>\n<li>User manual<\/li>\n<li>Standard gold-plated test leads x2<\/li>\n<li>Test leads with fine tips x2<\/li>\n<li>Batteries x2<\/li>\n<li>Type K thermocouple x1<\/li>\n<\/ul>\n<div class=\"table-wrapper\">\n<p>\u00a0<\/p>\n<h3>Specifications<\/h3>\n<table>\n<tbody>\n<tr>\n<th>Manufacturer<\/th>\n<td>Uni-T<\/td>\n<\/tr>\n<tr>\n<th>Model<\/th>\n<td>UT18B MAX<\/td>\n<\/tr>\n<tr>\n<th>Type<\/th>\n<td>True RMS digital multimeter<\/td>\n<\/tr>\n<tr>\n<th>DC voltage<\/th>\n<td>600.0 mV \/ 6.000 V \/ 60.00 V \/ 600.0 V \/ 1000 V \u00b1(0.4%+3)<\/td>\n<\/tr>\n<tr>\n<th>AC Voltage<\/th>\n<td>600.0 mV \/ 6.000 V \/ 60.00 V \/ 600.0 V \/ 1000 V \u00b1(0.5%+5)<\/td>\n<\/tr>\n<tr>\n<th>VFD<\/th>\n<td>600.0 V \u00b1(8%)<\/td>\n<\/tr>\n<tr>\n<th>AC current<\/th>\n<td>600.0 \u00b5A \/ 6000 \u00b5A \/ 60.00 mA \/ 600.0 mA \/ 6.000 A \/ 10.00 A \u00b1(1.2%+3)<\/td>\n<\/tr>\n<tr>\n<th>DC current<\/th>\n<td>600.0 \u00b5A \/ 6000 \u00b5A \/ 60.00 mA \/ 600.0 mA \/ 6.000 A \/ 10.00 A \u00b1(1.2%+3)<\/td>\n<\/tr>\n<tr>\n<th>Resistance<\/th>\n<td>600.0\u03a9 to 60.00M\u03a9 \u00b1(0.5%+2)<\/td>\n<\/tr>\n<tr>\n<th>Capacitance<\/th>\n<td>6.000nF to 6000\u00b5F \u00b1(2.0%+5)<\/td>\n<\/tr>\n<tr>\n<th>Frequency<\/th>\n<td>10Hz ~ 10MHz \u00b1(0.1%+3)<\/td>\n<\/tr>\n<tr>\n<th>Duty Cycle<\/th>\n<td>1% ~ 99.9% \u00b1(1.0%+4)<\/td>\n<\/tr>\n<tr>\n<th>Temperature<\/th>\n<td>-55\u00b0C to 500\u00b0C \u00b12\u00b0C \/ \u00b14\u00b0F<\/td>\n<\/tr>\n<tr>\n<th>Display<\/th>\n<td>6000<\/td>\n<\/tr>\n<tr>\n<th>Continuity Test<\/th>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<th>Diode Test<\/th>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<th>LED Diode Test<\/th>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<th>Data Hold<\/th>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<th>MAX\/MIN Mode<\/th>\n<td>No<\/td>\n<\/tr>\n<tr>\n<th>Relative Mode<\/th>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<th>Backlight<\/th>\n<td>Adjustable<\/td>\n<\/tr>\n<tr>\n<th>Range switching<\/th>\n<td>Automatic and manual<\/td>\n<\/tr>\n<tr>\n<th>Auto power off<\/th>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<th>Wake-up with any button<\/th>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<th>Visual and audible alarm<\/th>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<th>Warped wire connection alarm<\/th>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<th>Voltage category<\/th>\n<td>CAT III 600V<\/td>\n<\/tr>\n<tr>\n<th>Power Supply<\/th>\n<td>2x 1.5V AA batteries<\/td>\n<\/tr>\n<tr>\n<th>Weight<\/th>\n<td>455 g<\/td>\n<\/tr>\n<tr>\n<th>Dimensions<\/th>\n<td>182 mm \u00d7 91 mm \u00d7 45 mm<\/td>\n<\/tr>\n<tr>\n<th>Color<\/th>\n<td>Red and gray<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Uni-T True RMS UT18B MAX Digital Multimeter The Uni-T UT18B MAX is the most advanced model in this series, designed for users who need not only standard electrical measurements but also an additional LED testing function.
