Produced by HT Italia SRL of Faenza, Italy, it combines the core electrical measurement functions—DC and AC voltage, DC current, resistance, and continuity—with dedicated diode and battery-test modes in a single battery-powered instrument. A digital multimeter is a foundational diagnostic tool on the electronics bench, converting voltage, current, and resistance at its input terminals into a numeric reading on its display. It lets a technician confirm whether a circuit is energized, whether a component is within tolerance, and whether continuity exists across a connection—the first questions in most troubleshooting sequences. ValueTronics keeps the HT25N and the rest of its test-and-measurement catalog under its own roof in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where inventory is stocked and held rather than sourced on demand. ## Product Core & Specifications Specification Value DC Voltage (Accuracy = reading + digits, at 18°C–25°C, <75%RH) 200.0 mV range (res. 0.1 mV) ±(0.7% rdg + 3 dgt); input impedance >1 MΩ; overload protection 200 Vrms 2000 mV range (res. 1 mV) ±(0.7% rdg + 3 dgt); input impedance >1 MΩ; overload protection 600V DC/AC 20.00 V range (res. 0.01 V) ±(0.7% rdg + 3 dgt); input impedance >1 MΩ; overload protection 600V DC/AC 200.0 V range (res. 0.1 V) ±(1.0% rdg + 3 dgt); input impedance >1 MΩ; overload protection 600V DC/AC 600 V range (res. 1 V) ±(1.0% rdg + 3 dgt); input impedance >1 MΩ; overload protection 600V DC/AC AC Voltage (50–60 Hz) 200.0 V range (res. 0.1 V) ±(1.5% rdg + 12 dgt); input impedance >1 MΩ; overload protection 600V DC/AC 600 V range (res. 1 V) ±(1.5% rdg + 12 dgt); input impedance >1 MΩ; overload protection 600V DC/AC DC Current 2000 µA range (res. 1 µA) ±(1.5% rdg + 3 dgt); voltage drop 200 mV; overload protection Fast Fuse 200 mA / 600V 20.00 mA range (res. 0.01 mA) ±(1.5% rdg + 3 dgt); voltage drop 200 mV; overload protection Fast Fuse 200 mA / 600V 200.0 mA range (res. 0.1 mA) ±(1.5% rdg + 3 dgt); voltage drop 200 mV; overload protection Fast Fuse 200 mA / 600V 10.00 A range (res. 0.01 A) ±(2.5% rdg + 2 dgt); overload protection Fast Fuse 10 A / 600V Resistance and Continuity Test 200.0 Ω range (res. 0.1 Ω) ±(1.2% rdg + 4 dgt); buzzer <60 Ω; overload protection 250 Vrms < 15 sec 2000 Ω range (res. 1 Ω) ±(1.2% rdg + 4 dgt); overload protection 250 Vrms < 15 sec 20.00 kΩ range (res. 0.01 kΩ) ±(1.2% rdg + 4 dgt); overload protection 250 Vrms < 15 sec 200.0 kΩ range (res. 0.1 kΩ) ±(1.2% rdg + 4 dgt); overload protection 250 Vrms < 15 sec 2000 kΩ range (res. 1 kΩ) ±(1.5% rdg + 2 dgt); overload protection 250 Vrms < 15 sec Diode Test Test current approx 1 mA Max. open voltage approx 2.8 V Battery Test 1.5 V range (res. 1 mV) ±(1.5% rdg + 3 dgt); test current 100 mA 9 V range (res. 10 mV) ±(1.5% rdg + 3 dgt); test current 6 mA Display Type LCD, 3½ dgt, 2000 points plus sign and decimal point Polarity Automatic polarity indication Backlight Yes Overrange indication “OL” Features Data hold HOLD Low battery indication “BAT” appears when the battery voltage is low General Operating temperature 0°C to 50°C, <70%RH Storage temperature \-20°C to 60°C, <80%RH Max altitude 2000 m Pollution degree 2 Insulation Double insulation Power supply 1 x 9V battery NEDA 1604 IEC 6F22 Battery life ca 30h (backlight ON), ca 130h (backlight OFF) Protection fuses Fast 10 A / 600V, 5x20 mm (10 A input); Fast 200 mA / 600V, 5x20 mm (mA/µA input) Dimensions (L x W x H) 150 x 70 x 48 mm Mechanical protection IP40 Weight (included battery) 255 g Safety IEC/EN61010-1 CAT III 600V to ground EMC IEC/EN61326-1 > **Important:** Current inputs are protected by fast 5x20 mm fuses: 10 A/600 V on the 10 A input and 200 mA/600 V on the mA/µA input. > **Important:** Safety rating: IEC/EN61010-1 CAT III 600V to ground; double insulation, pollution degree 2, max altitude 2000 m. ## About this New unit This is a brand-new, factory-sealed unit, supplied exactly as it arrives from the manufacturer and backed by the full manufacturer warranty.
