175, 177, 179 Users Manual • Examine the case before you use the Product. Look for cracks or missing plastic. Carefully look at the insulation around the terminals. • Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc. • Keep fingers behind the finger guards on the probes. • Do not use the Product around explosive gas, vapor, or in damp or wet environments. • Use only current probes, test leads, and adapters supplied with the Product. • Do not work alone.
PAGE 7
True-rms Multimeters Symbols • The battery door must be closed and locked before you operate the Product. • Use only cables with correct voltage ratings. • Remove all probes, test leads, and accessories before the battery door is opened. • Replace the batteries when the low battery indicator shows to prevent incorrect measurements. • Do not apply more than the rated voltage, between the terminals or between each terminal and earth ground.

True-rms Multimeters Battery Saver (Sleep Mode) Battery Saver (Sleep Mode) To use MIN MAX AVG recording: The Product enters the Sleep mode and the display goes blank if there is no function change or button press for 20 minutes. To disable the Sleep mode, hold down  while turning the Product on. The Sleep mode is always disabled in the MIN MAX AVG mode and the AutoHOLD mode. 1. Set the desired measurement function and range. (Autoranging is disabled in the MIN MAX AVG mode.

175, 177, 179 Users Manual Display HOLD and AutoHOLD Modes XW Warning Manual Range and Autorange The Product has both Manual range and Autorange modes. • In the Autorange mode, the Product selects the range with the best resolution. To avoid electric shock, fire, or personal injury, do not use the Display HOLD or AutoHOLD mode to determine if a circuit is live. Unstable or noisy readings will not be captured. • In the Manual Range mode, override Autorange and select the range yourself.

175, 177, 179 Users Manual Measure AC or DC Current XW Warning DC To prevent possible electrical shock, fire, or personal injury: • Never attempt to make an in-circuit current measurement when the open-circuit potential to earth is >1000 V. • Check the Product's fuses before testing. (See Test the Fuses.) • Use the proper terminals, switch position, and range for your measurement.

True-rms Multimeters Basic Measurements Measure Frequency AC Current Frequency XW Warning To prevent possible electrical shock, fire, or personal injury, disregard the bar graph for frequencies >1 kHz. If the frequency of the measured signal is >1 kHz, the bar graph is unspecified. x2 Hz HOLD MIN MAX RANGE mA The Product measures the frequency of a signal. The trigger level is 0 V, 0 A ac for all ranges. AC/DC Voltage Frequency HOLD MIN MAX RANGE + A aik16.
PAGE 20
175, 177, 179 Users Manual Use the Bar Graph Maintenance The bar graph is like the needle on an analog meter. It has an overload indicator () to the right and a polarity indicator (±) to the left. Because the bar graph updates about 40 times per second, which is 10 times faster than the digital display, the bar graph is useful for making peak and null adjustments and for observing rapidly changing inputs.
PAGE 21
True-rms Multimeters Maintenance Clean the Product Replace the Battery and Fuses Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture in the terminals can affect readings. Test the Fuses XW Warning To prevent possible electrical shock, fire, personal injury, or damage to the Product: • Remove the test leads and any input signals before replacing the fuse. • Use ONLY fuses with the amperage, interrupt, voltage, and speed ratings specified.
