INTRODUCTION

Thank you for purchasing an AEMC® Digital Flexbprobe.

For best results and for your safety, read the enclosed operating instructions carefully and comply with the precautions for use.

PRECAUTIONS BEFORE USE

This instrument is protected against voltages of not more than 1000V with respect to ground in measurement CAT III or 600V in CAT IV between the sensor and the conductor that measures the current.

The protection provided by the instrument may be impaired if the instrument is used other than as specified by the manufacturer.

• Do not exceed the rated maximum voltage and current or the measurement category.
• Observe the conditions of use; temperature, relative humidity, altitude, level of pollution, and location.
• Before each use, check the integrity of the insulation on the sensor, cable and housing. Do not use the instrument if it is open, damaged, poorly assembled, or if its accessories appear damaged.
• The sensor must not be applied to or removed from uninsulated conductors at dangerous voltages.
• Use personal protection equipment systematically.
• All troubleshooting and metrological checks must be performed by competent and accredited personne

International Electrical Symbols

PRODUCT FEATURES

Description
An ideal addition to the electrician’s tool kit, the Digital FlexProbe® series can be used for TRMS AC current measurements from 20mA to 4000A, and are rated 600V CAT IV. They provide a welcomed solution when  accessing electrical conductors is difficult and in tight places.

Two models are available. The Model 400D, available with either a 6″ or 10″ sensor, has a measurement range starting at 20mA, and is designed for work in residential, commercial and light industrial applications. It can be used to check electrical distribution systems up to 400A.

The Model 4000D, available with a either a 14″ or 24″ sensor, has a measurement range starting at 100mA and can be used on higher-power industrial installations, as well as electrical utilities for measurements up to 4000A.

Although they are high-performance instruments, the Digital FlexProbe® series remain very simple to use: two buttons are all it takes to start the instrument, deactivate the auto power-off, HOLD the value on the displayor store the maximum value (MAX HOLD). The values are read directly on the built- in 4000-count display

They are ergonomically designed for comfortable handheld use even  when bulky gloves are required. The optional articulating, magnetic Multifix mounting system accessory makes it simple to hang on a wall, door, table edge or clip onto a belt.

Control Features

1. Flexible sensor
   • Model 400D (6″, 10″)
   • Model 4000D (14″, 24″)
2. Sensor opening/closing lever
3. Shielded lead
4. Protective housing
5. LCD display
6. ON/OFF button
7. HOLD button

On the back of the protective housing is a notch for the attachment of a belt clip (optional)

With the Multifix magnetic mounting accessory, you can position your Digital FlexProbe® anywhere, leaving both hands free. The Multifix can be used to:

• Carry the Digital Flexprobe® on a belt
• Attach it to a metal surface using the built-in magnet
• Attach it to a door top or the edge of a table
  

OPERATION

Measurement Principle
The flexible sensor is based on the Rogowski coil. This principle combines:

• Excellent linearity with no saturation effect (therefore no heating)
• Light-weight (no magnetic circuit)

Use
Connection

1. Press the locking clip(s) to open the sensor.
2. Place the sensor around the conductor through which the current to be measured flows (only one conductor in the sensor), then close the sensor.
3. In order to optimize measurement quality, it is best to center the conductor in the coil and make the shape of the coil as nearly circular as possible.
4. Press the button to turn the instrument on.

Measurement
Read the measurement on the display. The current is given in Arms.

If the measurement exceeds the display capacity (4000A), the device displays 3999, blinking.

If the measurement is too low (see § 3.2), the device displays dashes

If the edges of the signal are too steep, or its peak factor is too large, the device displays OL.

Freezing the Measurement
If you want to freeze the dicsplay of a measurement, press the HOLD button. The HOLD symbol is displayed.

The device continues to make measurements, but the display is frozen. To release it, press the HOLD button again.

Search for Maximum
To search for a maximum, for example a spike lasting at least 100ms, press the HOLD (MAX > 2s) button for more than two seconds. The Max symbol will display and the instrument will begin measuring.

The Digital Flexprobe® compares each new measurement to the one displayed. If the new measurement is greater than the old, it replaces it in the display.

To return to the real-time display mode, press the HOLD (MAX > 2s) button again

Auto Power OFF
If there is no activity after 10 minutes, the Digital Flexprobe® turns off automatically (unless the MAX function is active) to preserve battery life.

To deactivate the Auto Power OFF feature, press the and HOLD buttons simultaneously when turning the instrument on.

To reactivate automatic switching off, switch the device off, then back on.

Low Battery
When the battery voltage drops and the remaining battery life of the instrument is approximately one hour, the symbol blinks on the display.

When the battery voltage is too low to guarantee the accuracy of a measurement, the symbol lights steadily. The batteries must then be replaced (see § 5.2).

Disconnecting
Turn off the device by pressing the button. Press the yellow opening lever to open the flexible sensor. Remove the sensor from the conductor.
