APPA sFLEX 18D Flexible Current Probe Meter

Product Information

The sFLEX 18D is a flexible current probe meter that is designed to measure AC current. It has a 3000-count display and over-range display. The dimensions of the device are approximately 130mm x 350mm x 25mm and weighs 200g (without battery). It requires two AAA size batteries and has a battery life of 200 hours. The device is designed to conform to EU directives and safety standards such as EN61010-1, EN61010-2-032, and EN61326-1 CAT IV 600V, CAT III 1000V.
The conversion rate is 4 times/second, and the frequency response is 45 – 500Hz (Sine Wave).

Product Usage Instructions

Safety Information: To ensure safe operation and service of the meter, follow the instructions provided in the user manual. Failure to observe warnings can result in severe injury. Identify hazardous conditions and actions that could cause bodily harm or death – individual protective equipment should be used if necessary.

Maintenance: Do not attempt to repair this clamp meter. It contains no user-serviceable parts. Repair or servicing should only be performed by qualified personnel. Periodically wipe the case with a dry cloth and detergent. Do not use abrasives or solvents.

Power on/off: To turn off the device, press the power button for more than 2 seconds.

Flexible AC current probe: To unlock the probe, slide the unlock button to the right. Do not touch the area above the LCD during measurement.

Auto Power off Function: The device has an auto power off function that turns off the device after 20 minutes of inactivity. To disable this function, press the power button and during the LCD shows battery capacity, press the backlight button until the LCD shows “AoFF.”

Backlight: To turn on the backlight, press the
backlight button.

Data Hold: To freeze the reading, press the
data hold button.

Safety Information

To ensure safe operation and service of the meter, follow these instructions. Failure to observe warnings can result in severe Injury.

Warning
Identify hazardous conditions and actions that could cause BODILY HARM or DEATH .

•  Individual protective equipment should be used if HAZARDOUS LIVE parts in the installation where measurement is to be carried out could Be ACCESSIBLE.
•  If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
• To reduce the risk of fire or electric shock, do not expose this product to rain or moisture.
• Verify the Meter operation by measuring a known Current. If in doubt, have the Meter serviced.
• Do not apply more than the rated voltage/Current, as marked on Meter.
•  To avoid false readings that can lead to electric shock and injury, replace battery as soon as low battery indicator.
• Do not use Meter around explosive gas or vapor.
• Do not use a flexible current sensor if the inner copper wire of the flexible cord is visible.
• De-energize the installation under test or wear suitable protective clothing during fitting a removal of the Flexible Current Probe.
• Do not apply around or remove from UNINSU LATED HAZARDOUS LIVE conductors, which may render electric shock, electric burn, or arc flash.

Caution
Identify conditions and actions that could cause DAMAGE the meter or equipment under test. Do not expose Meter to extremes in temperature of high humidity.
