Introduction The Fluke 15B+/17B+/18B+ Digital Multimeters (the Product) are 4000 count instruments. The Product is battery powered with a digital display. Except where noted, the descriptions and instructions in this Users Manual apply to all of 15B+/17B+/18B+. Unless otherwise identified, all illustrations show the 17B+.
15B+/17B+/18B+ Users Manual Product Overview Table 1 shows the terminals on the Product. Table 1. Terminals Item Description Input terminal for ac and dc current measurement to 10 A and frequency (17B+/ 18B+) measurements. Input terminal for ac and dc microamp and milliamp measurements to 400 mA and frequency (17B+/18B+) measurements.
Digital Multimeters Auto Power Off Table 2 shows the display of the Product. Table 2. Display Item Description Item Description Relative measurement is enabled Duty cycle is selected (17B+/ (17B+ only). 18B+). High voltage Resistance or Frequency (17B+/ 18B+) is selected. Continuity is selected.
15B+/17B+/18B+ Users Manual Auto Backlight Off The backlight automatically turns off after 2 minutes of inactivity. To disable the Auto Backlight Off function, hold down D when turning on the Product, until LoFF shows on the display. Measurements XW Warning To prevent possible electrical shock, fire, or personal injury, disconnect power and discharge all high-voltage capacitors before you measure resistance, continuity, capacitance, or a diode junction.
Digital Multimeters Measurements 2. Push to store the measured reading as the reference value and activate the relative measurement mode. The difference between the reference value and subsequent reading shows on the display. 3. Push for to return to normal operation. MIN MAX Mode (17B+ Only) To set the Product to MIN MAX mode (available for all functions except resistance, capacitance, frequency, duty cycle, and diode):...
15B+/17B+/18B+ Users Manual Measure AC or DC Current XW Warning To prevent possible electrical shock, fire, or personal injury, remove circuit power before you connect the Product in the circuit when you measure current. Connect the Product in series with the circuit. To measure ac or dc current: 1.
Digital Multimeters Measurements Test for Continuity To test for continuity: 1. With the resistance mode selected, push D once to activate the continuity beeper. If the resistance is <70 Ω, the beeper will sound continuously, designating a short circuit. 2. See Figure Figure 3.
15B+/17B+/18B+ Users Manual Measure Capacitance W Caution To prevent damage to the Product, disconnect circuit power and discharge all high-voltage capacitors before you measure capacitance. To measure: 1. Turn the rotary switch to 2. Connect the red test lead to the terminal and the black test lead to the COM terminal.
Digital Multimeters Measurements Test LEDs (18B+ Only) W Caution To prevent possible damage to the Product or to the equipment under test, disconnect all test leads from any hazardous voltage before you switch to the LED TEST function. The Product tests Light Emitting Diodes (LEDs) either through the LED test socket on the Meter or through the test leads.
15B+/17B+/18B+ Users Manual Maintenance Beyond replacing batteries and fuses, do not attempt to repair or service the Product unless you are qualified to do so and have the relevant calibration, performance test, and service instructions. The recommended calibration cycle is 12 months. XW Warning To prevent possible electrical shock, fire, or personal injury: Remove the input signals before you clean the Product.
Digital Multimeters Maintenance Replace Batteries and Fuses XW Warning To prevent false readings, which could lead to possible electric shock or personal injury, replace the batteries as soon as the battery indicator ( ) appears. To prevent damage or injury, install ONLY replacement fuses with the specified amperage, voltage, and interrupt ratings.
15B+/17B+/18B+ Users Manual Service and Parts If the Product fails, first check the batteries and fuse, and then review this manual to make sure that you are operating the Product correctly. Replacement parts are listed in Table Table 3. Replacement Parts Item Description Part Number Battery, IEC LR6...
