APPA 170 Series Clamp Meter
Product Information
The 170 series is a clamp meter that can measure both direct and alternating current. It features a 6,000 count digital display, input terminals for multi- function, and a common (ground reference) input terminal. The meter includes various functions such as capacitance, DCV/DCmV, ACV, resistor/continuity, capacitor/diode, frequency, MIN/MAX, Volt Seek, HFR/INRUSH, backlight, torch light, data logger, Bluetooth, AC 600A, DC 600A, DC/AC 1500A, DC/AC A, LoZ, PV voltage, temperature, and flexible current. The meter is also equipped with safety features including tactile barriers for hand guard and an alert system for potentially hazardous voltage.
Product Usage Instructions
Preparation and Caution Before Measurement
Observe the rules of warnings and cautions. When connecting the test leads
to the DUT (Device Under Test), connect the common test leads before
connecting the live test leads; when removing the test leads, remove the live
test leads before removing the common test leads. Preparation and Caution
Before Measurement Observe the rules of Warnings and Cautions.
CAUTION
When connecting the test leads to the DUT (Device Under Test) connect the
common test leads before connecting the live test leads ; when removing the
test leads, remove the live test leads before removing the common test leads.
Measuring Voltage
Dial the switch to select the measuring function. In LoZ mode, the meter
displays the measurement result at AC or DC value, depending on whichever is
greater. Do not use the LoZ mode to measure voltages in circuits that could be
damaged by this mode’s low impedance.
Dial the switch to select the measuring function.
LoZ mode : Display measurement result at AC or DC value, it depends on whichever is greater.
CAUTION
Do not use the LoZ mode to measure voltages in circuits that could be damaged
by this mode’s low impedance.
Measuring PV Voltage
To measure PV voltage, dial the switch and press the Function button to
select AC/DC mode. This function is only available with the dedicated PV test
probe (APPA ATL-PV). Always select the correct DC/AC mode to perform high
voltage measurement. This meter will flash a symbol and the correct mode
symbol (AC/DC) if the input voltage is different and dangerous. Dial the
switch and press the Function button to select AC/DC mode.
CAUTION
This function is only available with the dedicated PV test probe (APPA ATL-
PV). Always select correct DC / AC mode to perform high voltage measurement.
This meter will flash symbol and the correct mode symbol (AC / DC) if the
input voltage is different and dangerous.
Measuring Current
To measure current, dial the switch and press the Function button to select
the measuring function. Note that the torch will be on when the jaw is opened.
The meter is equipped with safety features including tactile barriers for hand
guard and an alert system for potentially hazardous voltage. When measuring
current, ensure that the meter is held with respect to earth for the jaw and
do not hold the meter across the barrier. Dial the switch and press the
Function button to select the measuring function.
Note : Torch will be on when jaw is opened.

WARNING
- If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
- Always use proper terminals, switch position, and range for measurements.
- To reduce the risk of fire or electric shock, do not use this product around explosive gas or in damp locations.
- Verify the Meter operation by measuring a known voltage. If in doubt, have the Meter serviced.
- Do not apply more than the rated voltage, as marked on Meter, between terminals or between any terminal and earth ground.
- To avoid false readings that can lead to electric shock and injury, replace the battery as soon as low battery indicator blinks.
- Avoid working alone so assistance can be rendered.
- Do not use the Tester if the Tester is not operating properly or if it is wet.
- Individual protective device must be used if hazardous live parts in the installation where the measurement is to be carried out could be accessible.
- Disconnect the test leads from the test points before changing the position of the function rotary switch.
- Never connect a source of voltage when the function rotary switch is not in voltage position.
- When using test leads or probes, keep your fingers behind the finger guards.
- Use caution with voltages above 30 Vac rms, 42 Vac peak, or 60 Vdc. These voltages pose a shock hazard.
- Remove test lead from Meter before opening the battery door or Meter case.
- DO NOT USE the test leads when the internal white insulation layer is exposed.
- DO NOT USE the test leads above maximum ratings of CAT. environment, voltage and current, that are indicated on the probe and the probe tip guard cap.
- DO NOT USE the test leads without the probe tip guard cap in CAT III and CAT IV environments.
- Probe assemblies to be used for MAINS measurements shall be RATED as appropriate for MEASUREMENT CATEGORY III or IV according to IEC 61010-031 and shall have a voltage RATING of at least the voltage of the circuit to be measured.
- Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance.
- De-energize the installation under test or wear suitable protective clothing during fitting and removal of the Flexible Current Probe.
- Do not apply around or remove from UNINSULATED HAZARDOUS LIVE conductors, which may render electric shock, electric burn, or arc flash.
- Do not apply a current with frequency that is higher than the frequency response range specified in the Electrical specification section to APPA 172 .
