Digital Solar True RMS Clamp Meter DT4545PRO

AC Voltage:

Input impedance: 10 MΏ, Overload protection: 2000 V DC or 2000 V AC (RMS). Maximum input voltage: 2000 V AC (RMS)

Frequency range: 40 Hz to 1 kHz

Response: True RMS. Note: When measuring AC or DC voltages in the low-voltage range, if the test leads are not connected to the circuit under test, the meter may fluctuate; this is normal and is caused by the meter’s high sensitivity. When the probes are connected to the circuit under test, you will obtain the actual measurement value.

DC Voltage

Maximum input voltage: 2000 V DC RMS

Input impedance: 10 MΩ

Capacitance:

Overload Protection:250 V DC/AC

Resistance:

AC Current:

Maximum input current: 2000A / Frequency range: 50–60 Hz / Response: True RMS

-When measuring AC current, place the conductor to be tested in the centre of the clamp jaws. If not centred, the maximum positional error may increase by 1.5%.

-On the AC current range, briefly press the INR key to select INRUSH surge current measurement. At this point, power on the electrical device to measure its instantaneous inrush current; surge current measurement is available only on the 2000A range.

DC Current:

input current: 2000A

Due to the presence of external electromagnetic fields such as the Earth’s, to ensure the accuracy of the measurement reading, press the ZERO key to set the reading to zero. If the reading is still not zero after pressing the key, press it several times until the reading is zero. Note: Due to the high sensitivity of the product, to ensure accurate readings, the orientation of the instrument during measurement should be as consistent as possible with the orientation during zeroing.

Temperature Measurement:

Temperature specifications do not include thermocouple error.
