and has left the factory in perfectly safe technical condition.

To maintain this condition and to ensure safe operation of the multimeter, the user must observe the notes and warnings given in these instructions at all times. Improper handling and non-observance of the warnings might involve severe injuries or danger to life.

WARNING! Be extremely careful when working with bare conductors or main line carrier! Contact with live conductors will cause an electric shock!

The BENNING CM 5-1 may be used only in electrical circuits of over voltage category III with a maximum voltage of 1000V or of over voltage category IV with a maximum voltage of 600V between the conductor and ground.

Only use suitable measuring leads for this. With measurements within measurement category III or measurement category IV, the projecting conductive part of a contact tip of the measuring leads must not be longer than 4mm

Prior to carrying out measurements within measurement category III and measurement category IV, the push-on caps provided with the set and marked with CAT III and CAT IV must be pushed onto the contact tips. The purpose of this measure is user protection.

Remember that work on electrical components of all kinds is dangerous. Even low-voltages of 30V AC and 60V DC may be dangerous to human life.

Before starting the multimeter, always check it as well as all measuring leads and wires for signs of damage.

Should it appear that safe operation of the multimeter is no longer possible, it should be shut down immediately and secured to prevent that it is switched on accidentally.

It may be assumed that safe operation is no longer possible:

• if the instrument or the measuring leads show visible signs of damage, or
• if the multimeter no longer works, or
• after long periods of storage under unfavourable conditions, or
• after being subject to rough transportation, or
• if the device or the measuring leads are exposed to moisture, or
• if the self-test fails and „FAIL“ is shown on the display.

In order to avoid danger,

• do not touch the bare probe tips of the measuring leads,
• insert the measurement leads in the appropriately designated measuring sockets on the multimeter

Maintenance:

Do not open the multimeter, because it contains no components which can be repaired by the user. Repair and service must be carried out by qualified personnel only!

7. Electrical specifications

Note: The measuring precision is specified as the sum of

• a relative fraction of the measured value and
• a number of digits (counting steps of the least significant digit).
  This specified measuring precision is valid for temperatures within the range of 18^ to 28^ and for a relative humidity lower than 80% .

7.1 Priority of the AUTOTEST function

The AUTOTEST function automatically switches to the correct measuring function and automatically selects the ideal measuring range: For this, the BENNING CM 5-1 works according to the following order:

The following criteria must be met:
VAC, VDC whichever is greater	Voltage measurement active, if: 1.3 VAC ... 750.0 VAC 2.1 VDC ... 999.9 VDC - 0.7 VDC ... - 999.9 VDC
Ω / Diode	Resistance measurement active, if 0 Ω ... ∞ Ω 0.0 VAC ... 0.9 VAC - 0.4 VDC ... - 0.2 VDC 1.0 VDC ... 2.0 VDC
	Diode test active, if: 0.4 VDC ... 0.8 VDC (forward voltage)
AC, ADC whichever is greater	Current measurement active, if: 0.9 AC ... 600.0 AC 0.9 ADC ... 600.0 ADC

7.2 Direct voltage ranges

The input resistance for voltages of up to 30V is at least 4k . The input resistance increases to 375k for 750V with the input voltage increasing as well.

Measuring range Resolution Meas. precision			Overload protection*1
2.1 V ... 1000 V	0.1 V ± (0.3 % of the measuring value + 2 digits)	750 V	eff
-0.7 V ... - 1000 V	0.1 V ± (0.3 % of the measuring value + 2 digits)		750 V eff

Maximum measuring time = 30 seconds for voltages higher than 30 V

7.3 Alternating voltage ranges

The input resistance for voltages of up to 30V is at least 4k . The input resistance increases to 375k for 750V with the input voltage increasing as well.

Measuring range Resolution	Meas. precision*2 within the frequency range 50 Hz - 60 Hz	Overload protection*1
1.3 ... 750 V 0.1 V ± (0.9 % of the measuring value + 3 digits) 750 V		eff
within the frequency range 61 Hz - 500 Hz
1.3 ... 750 V	0.1 V ± (1.5 % of the measuring value + 3 digits)	750 Veff

Maximum measuring time = 30 seconds for voltages higher than 30 ~V

2 The measuring value is gained and indicated as effective value (True RMS, AC coupling). The measuring accuracy is specified for sinusoidal curves and applies to the final value of the measuring range as well as for non-sinusoidal curves up to 50% of the final value of the measuring range. In case of non-sinusoidal curves, the indicating value becomes inaccurate.

Thus, an additional error occurs for the following crest factors:
- crest factor from 1.4 to 2.0 additional error + 1 %
- crest factor from 2.0 to 2.5 additional error + 2.5 %
- crest factor from 2.5 to 3.0 additional error + 4 %

7.4 Direct current ranges

Measuring range Resolution Meas. precision			Overload protection
0.9 A ...600.0 A	0.1 A	± (2.0 % of the measuring value + 5 digit)	600 Aeff

The indicated accuracy is specified for conductors which are gripped by means of the measuring clamp 18 in the middle (see figure 3 direct/ alternating current measurement). For conductors which are not gripped in the middle, an additional error of 1% of the indicating value has to be considered.

Maximum remanence error: 1% (during repeating measurement)

7.5 Alternating current ranges

Measuring range	Resolution	Meas. precision *2 within the frequency range 50 Hz - 60 Hz	Overload protection
0.9 A ...600.0 A	0.1 A	± (2.0 % of the measuring value + 5 digit)	600 Aeff
		within the frequency range 61 Hz - 400 Hz
0.9 A ...600.0 A	0.1 A	± (2.5 % of the measuring value + 5 digit)	600 Aeff

2 The measuring value is gained and indicated as effective value (true RMS, AC coupling). The measuring accuracy is specified for sinusoidal curves

and applies to the final value of the measuring range as well as for nonsinusoidal curves up to 50% of the final value of the measuring range.

In case of non-sinusoidal curves, the indicating value becomes inaccurate.

Thus, an additional error occurs for the following crest factors:

crest factor from 1.4 to 2.0 additional error +1%

crest factor from 2.0 to 2.5 additional error +2.5%

crest factor from 2.5 to 3.0 additional error +4%

The stated precision is specified for conductors that are centrally clamped by the current clamp (see fig. 3 direct/ alternating current measurement). For conductors that are not centrally clamped, an additional error of 1% of the display value needs to be taken into account.
