Use Proper Power Cord. Use only the power cord specified for this product and certified for
the country of use, and make sure that no metal parts are exposed and the insulation is
broken.
Ground the Product. This product is grounded through the grounding conductor of the power
cord. To avoid electric shock, the grounding conductor must be connected to earth ground.
Before making connections to the input or output terminals of the product, ensure that the
product is properly grounded. The signal ground on the rear panel of the product is the same
as the ground potential.
Check the Wire. Check if the insulation of the test lead is damaged or if the lead is exposed;
check if the test lead is on, if there is any damage to the lead, replace it before using the
instrument.
Observe All Terminal Ratings. The voltage applied between the terminals or any one of the
terminals and the grounding point must not exceed the rated value indicated on the
instrument.
Do Not Touch Live Part. Do not touch exposed connection wires, unused inputs or circuits
being measured while the instrument is in use. When measuring voltages higher than 60V DC
or 30V AC, be sure to exercise caution and remember to keep your fingers away from the
meter's guard position to prevent electric shock.
Do Not Operate with Suspected Failures. If you suspect that this product is malfunctioning,
contact UNI-T's authorized service personnel for testing. Any maintenance, adjustment, or
