PRECAUTIONS FOR USE
The precautions for use listed below are imperative when using the instrument. Failure to comply with these instructions
may lead to electric shocks, explosions or fire.
 The operator will consult these instructions whenever the symbol is displayed.
 If you use the instrument in a way that is not specified, it’s safety level may be compromised, putting you in danger.
 When removing or inserting the battery and/or SD card, ensure that the measuring leads, sensors and mains power
are disconnected. The unit must be disconnected and powered down.
 The unit must not be used if the "battery/SD card" housing is absent, damaged or incorrectly fitted.
 The safety of any system incorporating this instrument is the responsibility of the system assembler.
 For your safety, only use the leads and suitable accessories delivered with the instrument: they comply with the
standard IEC 61010-031 (2002). When sensors or accessories of lower voltage and/or category level are connected to
the instrument, these lower levels and/or categories become applicable for the system.
 Before using it, always check that the leads, boxes and accessories are in perfect condition. Any leads, sensors or
accessories damaged insulation (even partially) must be repaired or scrapped.
 Comply with environmental conditions (See para 4.4.3)
 Use Personal Protection Equipment where required.
 This unit must be used for category IV installations, for voltages that do not exceed 600 V (AC or DC) in relation to the
earth (according to IEC standard 61010-1) or for voltages that do not exceed 1000 V for category III installations.
Never use on voltage networks or categories greater than those mentioned.
 Only use the mains power adaptor and battery packs supplied by the manufacturer. They have specific safety levels.
 Comply with the limits of the accessory or sensor safety levels. Avoid contact with unused terminals.
 Certain current sensors cannot be installed or removed from exposed live conductors: see the sensor’s manual and
comply with handling instructions.
Use and connection procedures:
 Switch the instrument on.
 Configure the unit for the required results and according to the type of network
 Connect the current leads and sensors to the unit
 Connect the earth and/or neutral lead to the network earth and/or neutral (when distributed) and the corresponding
current sensor
 Connect the L1 phase lead to the network L1 phase as well as the corresponding current sensor
 Repeat the procedure for phases L2, L3 and N
Note: complying with this procedure reduces connection errors to a minimum and avoids wasting time.
Disconnection procedures:
 Proceed in the reverse order to connecting always finishing by disconnecting the neutral (when distributed).
 Unplug the leads and switch off.
 Recharge the battery and recover the stored data where necessary.
USB is used for data transfer and the battery is re-charged with the mains power supply provided.

1. INTRODUCTION
The C.A 8335 (Qualistar+) is a three-phase AC+DC
1000 VRMS category III or 600 VRMS category IV
(IEC 61010-1) graphic display network analyser.
It has a dual role in the measurement of electrical
network parameters:
 measures electric distribution network values, powers
and disruptions
 live real-time images of sgl/three phase networks.
 stores trends, transients and alarm events over
planned recording campaigns.
The uncertainty of the CA 8335 is better than 1(not
included current sensor accuracy). In addition, it
provides great flexibility with a choice of different
sensors to measure from hundreds of milliamps
(MN93A) to several kiloamps (AmpFLEX™).
The unit is compact and shock resistant. It’s
ergonomics and simplicity of the user interface make it
easy and intuitive to use.
The CA8335 is aimed at technicians and engineers in
installation and electric network control and
maintenance teams.
The main measurements made are:
 The values of AC voltages up to 1000 V between
terminals
 The values of AC currents up to 6500 amps (neutral
included)
 Continuous value of voltages and currents (neutral
included)
 Voltage and current minimum and maximum half-
period values
 Peak values for voltages and current (neutral
included)
 Frequency of 50 Hz and 60 Hz networks
 Current and voltage peak factor (excluding neutral)
 Calculation of the K factor (KF) (application to
transformers in the presence of harmonic currents)
 Distortion factor (DF) for current and voltage
(excluding neutral)
 Global harmonics rate for current and voltage
(excluding neutral).
 Active, reactive (capacitive and inductive) and
apparent power by phase and cumulative (excluding
neutral).
 Power factors (PF) and displacement power factors
(DPF) (excluding neutral).
 Short-term voltage flicker (PST) (excluding neutral).
 Active, reactive (capacitive and inductive) and
apparent (excluding neutral) energy.
 Harmonics current and voltages (excluding neutral)
up to 50th: RMS value, percentages in relation to
fundamental, minimum and maximum and harmonics
sequences.
 Harmonics for apparent power up to rank the 50th:
value,
percentage in relation to the fundamental, minimum
and maximum.
 Motor start-up currents
