Frequently Asked Questions - PROFITEST PRIME AC Gossen Metrawatt
How do I perform an insulation resistance test?
Connect the test leads to the device under test. Select the Insulation Resistance function using the touchscreen. Choose the test voltage (e.g., 500 V) and press the Start button. The measurement will be displayed after a few seconds.
What RCD types can the PROFITEST PRIME AC test?
It supports RCD types A, AC, F, B, B+, EV, as well as selective (S) and delayed versions. You can test trip current and trip time with automatic sequences.
Can I transfer results to a PC?
Yes, via the USB-C or USB-A interface. Use the ETC software to download and manage your test data. Bluetooth is available as an option for wireless transfer.
What is the battery life?
The built-in Li-ion battery typically lasts for a full day of testing (approx. 8-10 hours) under normal use. It can be recharged via the mains adapter while the instrument is in use.
How to update the firmware?
Download the latest firmware from the Gossen Metrawatt website. Copy the update file to a USB flash drive (FAT32), insert it into the USB-A port, and follow the on-screen instructions in the system menu.
What is the maximum measurement voltage for insulation?
The tester can apply test voltages of 50, 100, 250, 500, and 1000 V DC. The maximum measurable insulation resistance is 1 GΩ.
Can it measure loop impedance without tripping RCDs?
Yes, using the selective loop impedance method with a low current, the tester can measure loop impedance on circuits with RCDs without causing them to trip.
Does the device come with a calibration certificate?
Yes, the PROFITEST PRIME AC ships with a factory calibration certificate traceable to DKD standards. Recalibration is recommended every 12 months.
What accessories are included?
The standard set includes: test leads with alligator clips, a mains adapter, a USB cable, a quick start guide, and a carrying case. Additional probes and adapters are available separately.
How to clean the touchscreen?
Use a soft, lint-free cloth slightly dampened with water or a mild screen cleaner. Do not spray liquids directly onto the device. Avoid abrasive materials.
