INTRODUCTION
The CA10 is a special-purpose electrical tester designed to quickly identify and
locate single faults in low-voltage (120/240V) AC distribution lines (branch
circuits). It can also test the reliability and response time of GFCIs (ground fault
circuit interrupters) and RCDs (residual current devices) and check the wiring of
outlet sockets. The instrument’s ease of use, versatility and accuracy make it
the ideal electrician’s tool for preventing shocks, sparks, electrical fires,
equipment damage and poor equipment performance.

KEY FEATURES
• Measures a branch circuit’s line voltage, peak voltage, neutral-to-ground
voltage and frequency
• Calculates a circuit’s voltage drop in response to a 12A, 15A or 20A load in
order to check the circuit's integrity
• Measures the impedance of hot, neutral and ground conductors as well as
available short-circuit current (ASCC)
• Tests the reliability and response time of GFCIs (ground fault circuit
interrupters) and RCDs (residual current devices)
• Measures and displays True RMS values of all voltages except peak
voltages
• Identifies wiring configurations and detects wiring faults and missing
ground wires
• Compatible with 2- and 3-phase circuits
• 2.4 in. diagonal LCD with 30-second backlight
• Familiar menu/sub-menu operation
• Data hold and 30-minute auto power off functions
• Includes 1 ft. long test cable and standard tripod mount
• Powered by six “AAA” batteries (included)
• One-year limited warranty
SAFETY INSTRUCTIONS
! WARNING! !
Exercise caution when working with exposed wiring.
Do not use this instrument on circuits carrying voltages higher than 265VAC.
WHAT’S IN THE BOX
The CA10 comes in an illustrated box containing a soft canvas carrying case.
Inside the case are the instrument, a 20 in. (0.5m) long test cable, six “AAA”
batteries and this user’s manual.

SETUP INSTRUCTIONS
INSTALL BATTERIES
The CA10 is powered by six “AAA” batteries (included).
To install the batteries:
1. Turn the unit over.
2. Remove the one Philips-head screw securing the battery compartment cover
(Figure 1, Callout 10) and set it aside.
3. Remove the battery compartment cover and set it aside as well.
4. Install the six supplied “AAA” batteries in the compartment, making sure to
match the polarity marks on the batteries with the marks stenciled inside the
compartment.
5. Replace the battery compartment cover and secure it with the Philips-head
screw.
ATTACH TEST CABLE
The test cable included with the CA10 has a plug compatible with Americanstyle 110VAC sockets. To attach the cable, plug it into the three-pronged socket
at the top of the CA10 (Fig. 1, Callout 1).
OPERATING INSTRUCTIONS
The symbols of the five main parameters/functions tested by the CA10—
voltage (V), voltage drop (Vd), conductor impedance (Z), RCD performance and
GFCI performance—are shown below as they appear on the bottom line of the
LCD. Use the FUNC button to move from any test to the test on its right. When a
test is selected, the border around its text icon is highlighted.
MEASURING VOLTAGE PARAMETERS
The CA10 can measure four parameters of an AC circuit voltage: 1) the True
RMS value of its phase voltage (L-N), 2) the True RMS voltage to earth (ground)
of its neutral line (N-E), 3) the peak value of the voltage (Peak), and 4) the
frequency of the voltage. Each of the first three parameters is measured and
displayed by choosing it from a submenu made available after the FUNC button
has been used to select V. By contrast, the frequency of each of the three
parameters is displayed on the top line of the LCD.
