instrument in anti-static area. Before connecting the cable to the instrument, the inner
and outer conductors should be grounded briefly to release the static electricity.
Pay attention to carrying safety.
To avoid the instrument sliding in the process of carrying, causing damage to the keys on
the panel, the knobs or interfaces, please pay attention to carrying safety.
Interference tests for all models comply with Class A standards, based on EN

Input terminal protection limits.
The protection limits are defined for the input terminals:
1. Main input (HI and LO) terminals.
The HI and LO input terminals are used for voltage, resistance,
capacitance, connectivity, frequency, and diode test measurements. These
two terminals define the following two protection limits:
1) HI to LO protection limit. The HI to LO protection limit is 1000 VDC or
750 VAC, which is also the maximum measurable voltage. This limit
can also be expressed as a maximum of 1000 VPK.
2) Lo to the ground protection limit. LO input terminals can safely "float" to a
maximum of 500 Vpk relative to the ground.
The HI terminal protection limit is up to 1000 VPK relative to the ground.
Therefore, the sum of the "floating" voltage and the measured voltage must not
exceed 1000 VPK.
2. Sampling terminal.
1) The HI and LO Sense terminals are used for DCV proportional
measurements, four-wire resistance and temperature measurements.
The measurement limit for all terminal pairs is 200 Vpk: LO Sense to
LO input, HI Sense to LO input, HI Sense to LO Sense.
3. Current input terminal.
The measurement limit is 10.5A (DC or AC) when using the 10A-current-
input terminal and the LO terminal. The measurement limit is 3.1A (DC or
AC) when using 3A-current-input terminal and the LO terminal.
Note:
To avoid blowing the fuse or damaging the multimeter, please follow the
instructions below to use the current input terminals.
1) When performing current test measurements, be sure to select an
appropriate current input terminal according to the expected current size
before switching on the multimeter power.
2) The maximum current input to 10A terminal shall not exceed 10.5A, otherwise, the
