Page 5: Operation
4) OPERATION Introduction To realize swift simultaneous dual measurements, the meter uses two Analog-to- Digital Converters (Duo) for its Clamp-on ACA functions (Upper-display readings) as well as its Rotary-switch functions (Lower-display readings) separately. Clamp-on ACA functions turn ON whenever the Rotary-switch function is turned ON. Regular &... - Page 6 Note: ACV and Hz functions are equipped with digital low-pass filter, and are capable of dealing with VFD (Variable Frequency Drives) signals for fundamental readings. It also improves ACV and Hz reading stability being in most noisy electrical environments. EF-Detection function with EF-H & EF-L Sensitivities The detected Electric Field strength is indicated as a series of bar-graph segments on the display together with variable beep tones.
- Page 7 ●Non-Contact EF-Detection (NCV): An antenna is located along the top-right end of the stationary clamp jaw, which detects electric field surrounding energized conductors. It is ideal for tracing live wiring connections, locating wiring breakages and to distinguish between live and earth connections. ●Probe-Contact EF-Detection: For more precise indication of live wires, such as distinguishing between Live and Ground connections, use direct contact testing with one single test-probe via an input terminal.
- Page 8 DCV function Inputs are made via the test lead terminals COM/+. WARNING: Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning.
- Page 9 Resistance & Continuity functions Inputs are made via the test lead terminals COM/+. Defaults at Resistance. Press SELECT button momentarily to toggle between the subject functions. Continuity function is convenient for checking wiring connections and operation of switches. The meter provides Audible as well as Visible results. A continuous beep and , indicates a complete wire.
- Page 10 Capacitance & Diode functions Inputs are made via the test lead terminals COM/+. Defaults at Capacitance. Press SELECT button momentarily to toggle between the subject functions. (For Model 173D, Capacitance and Diode functions are located in different rotary switch positions.) Note When using Diode test function, normal forward voltage drop (forward biased) for a good silicon diode is between 0.400V to 0.900V.

Large value capacitors should be discharged through an appropriate resistance load Temperature function (Models 176D & 175D only) Inputs are made via the test lead terminals COM/+. Press SELECT button momentarily to toggle between C (Celsius) and F (Fahrenheit).
- Page 12 DCA Current function (Models 176D & 175D only) Inputs are made via the test lead terminals COM/+. Application Notes on Flame Sensors: The DCA function is designed especially for HVAC/R flame sensor applications. The 0.1A resolution is useful for identifying the minute current changes in flame detector applications.
- Page 13 & 3-Phase Rotation function (Model 176D only) Inputs are made via the test lead terminals L1/L2/L3. Phase Rotation directions are indicated as symbolic movements by the LCD segments. Defaults at . Press SELECT button momentarily toggles between modes. Hi-sensitivity mode, which detects relatively low signal outputs generated from motor spinning, for checking phase connections of Motors.
- Page 14 Using the Hi-sensitivity mode for Motors: Connect to the Motor as illustrated. Be sure the electricity supply is removed. From the perspective of looking down the shaft of the motor, speed-spin it clockwise to generate sufficient signal strength for proper meter detection. If the meter indicates a clockwise movement, the motor leads connected to L1, L2 and L3 of the meter are L1, L2 and L3 (also known as R, S and T) respectively.

Page 15: Maintenance Warning
The Auto-Power-off (APO) mode turns the meter off automatically to extend battery life after approximately 32 minutes of no specified activities, where applicable: 1) Rotary switch or push button operations 2) Significant measuring readings of above 8.5% of ranges 3) Non-OL readings for Resistance, Continuity or Diode function 4) Non-zero readings for Hz function 5) Significant movement indication as in Phase Rotation functions In other words, the meter will intelligently avoid entering the APO mode when it is in... - Page 16 Accuracy and Calibration Accuracy is specified for a period of one year after calibration. Periodic calibration at intervals of one year is recommended to maintain meter accuracy. Refer to the LIMITED WARRANTY section for obtaining calibration, repairing or warranty service.
