HT Instruments ZG47 3 Phase Power Analyzer with Earth Ground Testing

Multifunction device for verification of electric safety and mains analysis on single-phase and three-phase installations

ZG47 is the complete and versatile multifunction device developed starting from real installation needs.
In a single device, all functions of the most advanced systems for safety testing (standards CEI 64.8) developed by HT; possibility of carrying out mains analyses, THREE-PHASE or SINGLE-PHASE (voltages, currents, powers, power factor, energies, etc.), voltage/current harmonic analysis (up to the 49th) and an analysis of the anomalies on power supply voltages (dips, peaks). The device has a whole variety of functions and can be used with external feelers for measuring environmental parameters such as temperature/humidity of air, illuminance (Lux) further to measuring leakage currents, Loop/Line impedance and calculating the assumed short-circuit current with high resolution (0.1mOhm) in TN systems with the use of the optional accessory IMP57. Cutting-edge management of measurement with indication, at the end of each safety test, of compliance or non-compliance with requirements with simple symbols OK or NOT OK.

DISPLAY DESCRIPTION
The display is a graphic module with a resolution of128 x 128 pixels The first line of the display shows date and time. If not correct, you can set the exact ones according to the procedure described

On the top right corner of the display you can always see the battery indicator and, if the external power supply adapter (code A0050) is connected, the corresponding symbol.

These symbols will be omitted in the following illustrations.

INITIAL SCREEN
When turning on the instrument by pressing ON/OFF, this screen will appear for a few seconds:
Here you can see:

serial number of the instrument (SN.:)
firmware software release (V.X.XX:)
transmission speed through serial RS232 (Baud Rate)
calibration date (CALIBRATION:)

BACKLIGHT FUNCTION
When instrument is turned on, pressing briefly the ON button, the backlight will be enabled. The light will be automatically turned off after 5 seconds. If the batteries are too low the instrument will disable automatically the backlight function.

INITIAL SETTINGS
By pressing the MENU key the following screen will be displayed:
It’s not possible to enter the MENU during a recording or a Real Time Energy measurement. Pressing this button during a recording the display will show main recording parameter.

Better than the DM-III

5.0

I had used the Amprobe DM-III a while back. They cancelled the product and I found this one and was told it was made by the same people who made the Amprobe Unit.

Well it works great is cheaper and has a nice 3 year warranty.
