Ordering Hioki instruments: what we need
Send the full order code, because Hioki uses suffixes to separate versions, for example sets with wireless adapters or different leads. Name the accessories you need, such as test leads, clamps, current sensors, the Z3210 wireless adapter and carrying cases, and say if a calibration certificate is required. If the model is uncertain, describe the circuit, the voltage and the quantity to be measured.
