General Tools and Instruments CA10 - Manual (Page 5)

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 American-
style 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.
