Thank you for purchasing this MX670 or MX675 series multimeter clamp. To obtain the best service from your unit: read these operating instructions carefully, comply with the precautions for use. 1 GENERAL INSTRUCTIONS If the device is used in a manner unspecified in these instructions, the protection provided by the device may be compromised. 1.1 Unpacking – Packing All instruments are checked mechanically and electronically before shipment.
1.2.2 Meaning of symbols used Symbol Meaning Instrument protected by double isolation. Symbol Alternating current. Direct current. CAUTION DANGER! Refer to the operating manual. Caution, risk of electrical shock Audible continuity test Clamp: Application or withdrawal authorized on conductors under dangerous voltage Meaning Ground. Battery. The CE marking guarantees conformity with European directives and with regulations covering EMC.
• • Always use the type of battery specified. Before opening the instrument, disconnect it from the measurement circuits, switch off and make sure you are not charged with static electricity, which would irreversibly damage the internal components of the instrument. 2 DESCRIPTION OF THE INSTRUMENT 2.
2.2 Description of LCD display MX670 MX675 MAX MIN HOLD Ω Auto power-off Max.
3 GENERAL DESCRIPTION 3.1 Correction of zero in DC measurement This function is present only on model MX675 to return to zero the display of the remanent magnetization of the clamp in DC measurement. When the switch is positioned on ADC and with no conductor inserted into the clamp, press the ADC ZERO & HOLD key (about 2 seconds) until display a of zero current appears. This reset to zero is also indicated by an audio beep and the display of the symbol ZERO.
MAX MIN function (500 ms) 3.6 To activate the MAX MIN function, press on the MIN MAX PEAK button. The MIN value is then displayed. (the MIN symbol is displayed steady; the MAX symbol is displayed flashing) By pressing again on the key, the MAX value will be displayed (the MIN symbol is displayed flashing; the MAX symbol is displayed and steady). By pressing the key again, the clamp returns to normal mode. 3.
4.2 DC voltage measurement • Position the switch on V . Connect the red test lead to the "+" terminal and the black test lead to the "COM" terminal. Put the touch prods in contact with the measurement points under DC voltage. Read the result of the measurement on the display. There is no secondary current display for model MX670. 4.3 Measuring AC current • Set the switch to A .
4.4 DC Current measurement (MX675 only) Set the switch to A . Once the display is stabilised, press the A ZERO & HOLD button to reset the display to zero. The operating procedure is then identical to that of AC measurement. See previous paragraph. Note: The correct display of current direction is the result of observing the positioning of the "+" indication on the clamp arm, in relation to the source. 4.5 Resistance measurement and Audio Continuity Test Set the switch to Ω . 4.5.
： 4.5.2 Audio Continuity Test： Connect the red test lead to the "+" terminal and the black test lead to the "COM" terminal. Put the touch prods into contact with the circuit to be tested. If the resistance value of circuit R<35 Ω , the buzzer sounds continuously. Note: Always check that the circuit is disconnected from the power supply before measuring continuity! 4.6 °C/°F Temperature Measurement Set the switch to TEMP.
4.7 Measurement of voltage frequency Position the switch on V , and press the DISPLAY key. Connect the red test lead to the "+" terminal and the black test lead to the "COM" terminal. Place the touch prods in contact with the points whose frequency is to be measured. Read the frequency value on the secondary display. The main display indicates the value of the measured TRMS voltage. 4.8 Measurement of AC current frequency Position the switch on A press the DISPLAY R , and key.
TECHNICAL SPECIFICATIONS 5 5.1 General The tolerances assigned to the values, or declared limits, constitute only the values guaranteed by the manufacturer. Values without a tolerance are for information only. The symbol is displayed when the input signals exceed the limit values possible in each measurement range. - The symbol is displayed in °C/°F measurement when there is no input signal (open circuit). 5.

5.4 General information Digital display: LCD dual display, 4 digits with max. indication of 9999 points. Polarity: When a negative signal is applied, the sign appears. Low Battery Indicator: is displayed when the voltage supplied by the battery is lower than the operating voltage. The measurements are then guaranteed for only a short period. Power supply: Battery: 9 V, NEDA 1604, 6F22 alkaline Typical autonomy: 35 hours (MX670) 30 hours (MX675) with alkaline battery, no buzzer or backlight.

6.2 Cleaning Keep the gap between the jaws in a state of perfect cleanliness. Set the instrument to the OFF position. Clean the unit with a cloth and a little soapy water. Wipe over with a damp cloth. Never use abrasive products or solvents. Dry carefully before any further use. 6.3 Storage If the instrument is not used for a period exceeding 60 days, remove the battery and store it separately. 6.4 Metrological verification Regular checks must be carried out as for all measurement or test devices.
