1. DESCRIPTION
The CA 5003 multimeter is designed for the daily needs of professionals in electricity.
It has the following functions:
- Voltmeter: voltage measurements (V
and
)
- Ammeter: current measurements (A
and
)
- Ohmmeter: resistance measurements (Ω) with automatic adjusting
- Continuity sound test [
]
SAFETY TERMINALS
Ø 4 mm safety terminals
COM :
common, terminal that receives the black lead
V
W
:
for voltages and resistances
15 A :
for the 15 A range
µmA :
for the µA, mA and 1,5 A ranges
6 SCALES DIAL
2 black, with parallax mirror, for VDC and AC
1 green for Ω
1 black for A DC
1 red for A AC
1 red for dB
FUSES CONTROL LIGHT
1,6 A and 16 A fuses on current or voltage measurement.
Change the fuses if light on (for V ≥ 110 V)
VOLTAGE PRESENCE LIGHT (V > 15 V) ON OHMMETER
If the «Voltest» light comes on, unplug the leads and cut off the voltage before
making the resistance measurement.
FUNCTIONS SELECTION SWITCH
2. REFERENCE CONDITIONS
Temperature:
22°C ± 2°K
Humidity:
45 % RH ± 5 %

Before all measurement, be sure the needle is on zero. Otherwise, turn the mechanical
zero adjusting screw situated under the battery door in order to do coincide the needle
with the zero of upper black scale (0.100).
Be sure the rotary switch is correctly positioned. When the order of magnitude is
not known, place the rotary switch on the highest range then progressively lower to
appropriate range : the reading must be made, preferably, in the upper 2/3 of the scale.
