Voltage detector ST9121 complies with IEC standard 61243-3 concerning test
equipment for low-voltage electrical installations.
This mark certifies this compliance.
The mobile probe can also be attached laterally alongside the main probe,
with a standard gap of 19mm from the 230V sockets to the safety eclipses.
The probes are equipped with contact plates with retractable cover for connection
to terminals 4mm in diameter.
The mini-flashlight at the end of the probe allows one to illuminate a dark area.
The AUTO TEST key checks the ST9121 before and after each use.
This LED indicates the presence of dangerous voltage, even with no batteries.
8 LEDs indicate DC or AC voltage from 12 to 690V DC or V AC 50Hz.
2 LEDs determine the polarity if voltage is DC or AC.
This LED lets one distinguish neutral phase(s).
The L and R LEDs determine the order of the L1 L2 L3 phases in three-phase setups.
VDC or VAC 50Hz 12,24,36,50,120,230,400,690 VAC or VDC
PHASE IDENTIFICATION from 100 to 690VAC - 50Hz to 60Hz
IMPEDANCE TEST rings if the tested resistance is < 30kOhms
PHASES ORDER (in 3-phase) indication of the order L1 L2 L3
AUTOTEST activate the voltage LED and the buzzer
SUPPLY two AAA 1,5V batteries
DIMENSIONS/WEIGHT 250x50x40mm / 220g
CASE with IP64 moulded holster
CARRYING CASE delivered in standard
Other characteristics
Double insulation
