You have just purchased a CA 6501 megohmmeter; thank you for your confidence.
For best results from your device:
- read this user manual attentively,
- observe the precautions for its use.
MEANINGS OF THE SYMBOLS USED
| AC – Alternating current
---|---
| Instrument fully protected by double insulation. No connection to the
protective earth is necessary.
| Selective sorting of wastes for the recycling of electrical and
electronic equipment within the European Union.In conformity with directive
WEEE 2002/96/EC: this equipment must not be treated as household waste.

Definitions of the measurement categories:
- Measurement category IV corresponds to measurements made at the source of the low-voltage installation.
- Measurement category III corresponds to measurements made in the installation of the building.
- Measurement category II corresponds to measurements made on circuits directly connected to the low-voltage installation.
- Measurement category I corresponds to measurements made on circuits not directly connected to the network.
PRECAUTIONS FOR USE
If this instrument is damaged or a part is missing, please contact the seller immediately.
This instrument is protected against accidental voltages up to 600V with respect to earth in measurement category II, 300V in category III.
Failure to observe the instructions or the precautions for use may compromise the protection provided by the instrument
Please refer to this manual for each danger symbol encountered.
To avoid an electric discharge, injury, or damage to this instrument, and make sure that you are using the megohmmeter in a risk-free manner, follow the safety recommendations below:
- This instrument can be used indoors or out (IP52) in environments where the degree of pollution does not exceed 2, at an altitude of less than 2000m, with voltages up to 600V (CAT II) or 300V (CAT III).
- Never use on a network of which the voltage or overvoltage category exceeds the stated values
- Before each use, check the integrity of the housing and of the insulation of the leads and accessories. Replace any damaged cords. Do not use the instrument if it seems damaged.
- Use leads and accessories satisfying safety standards (IEC 61010-031) for voltages and overvoltage categories at least equal to those mentioned.
- The use of suitable personal protective equipment is strongly recommended. Avoid working alone.
- Resistance and insulation measurements must be made only on circuits that are isolated and not live.
- Following an insulation measurement, leave the measurement leads connected for a few seconds before disconnecting in order to discharge the circuit tested.
- Disconnect the cords from the instrument before cleaning, changing the fuse, or opening the housing.
PRESENTATION
The CA 6501 is an electrical measuring instrument intended for the measurement of low resistance values (0 to 100Ω at 5mADC), of resistances (0 to 500kΩ at 1mADC), and for insulation measurements (0.5 to 200MΩ at 500VDC). The ohmmeter function is protected against the accidental presence of a voltage by a high- breaking-capacity fuse. A voltage-present indicator serves to make sure that there is no AC voltage in the circuit to be tested.
This instrument is ready for use at all times because it requires no operating maintenance. A magneto generator provides the various measurement and operating voltages.
DESCRIPTION OF THE VARIOUS PARTS, CONTROLS, AND FUNCTIONS
USE – CHARACTERISTICS:
RECOMMENDATIONS
The needle must indicate 0 when at rest in the voltmeter setting; if not,
adjust it using the black screw in the center (see picture above).
Do not connect the instrument to the terminals of a circuit of which the
voltage exceeds 600VAC or DC.
Before any resistance measurement, check that the circuit is not live (switch
set to voltmeter before connection).
After each insulation resistance measurement, let the circuit discharge
(needle on 0V; this takes a few seconds) before disconnecting the instrument.
Measurement input terminals:
These accept safety plugs 4mm in diameter.
Other indicatrs:
An orange indicator (Fig. 1) on the right side of the instrument indicates that the speed of the magneto is correct. When it is lit, the voltage between the terminals of the instrument is 500V, 650V, or 10VDC (noload), depending on the setting of the switch.
A red indicator (Fig. 2) on the left side of the instrument indicates the automatic change of range. When it is lit, multiply the reading by 10 to obtain the result.
OPERATION
MΩ measurement at 500VDC:
The measurement is made at a voltage of 500VDC above 0.5MΩ measured.
There is a change of reading coefficient for rising values: 20MΩ (changes to
X10 reading), and a change of reading coefficient for falling values: 5.5MΩ
(changes to X1 reading).
kΩ measurement at 1mADC:
The measurement is made with a current of 1mADC, from 0 to 500kΩ measured (650VDC max. no-load). There is a change of reading coefficient for rising values: 50kΩ (changes to X10 reading), and a change of reading coefficient for falling values: 45kΩ (changes to X1 reading).
Ω measurement at 5mADC:
The measurement is made with a current of 5mADC, from 0 to 100Ω measured (10VDC max. no-load). There is a change of reading coefficient for rising values: 10Ω (changes to X10 reading), and a change of reading coefficient for falling values: 9Ω (changes to X1 reading).
AC voltage measurement
The AC voltage measurement is from 0 to 600VAC in a single range (input impedance: 100kΩ), switch set to V.
GENERAL CHARACTERISTICS
Dimensions: 120mm x 120mm, height 130mm.
Mass: 1.06kg.
Degree of protection by housing:
IP54 with cover and IP52 without cover as per IEC 60529 (Ed. 92)
Power supply: This instrument is supplied by a magneto generator that provides the various measurement and operating voltages (speed of rotation: approximately 140 rpm). The voltmeter is supplied by the measurement input and so there is no need to operate the crank.
