The Triplett Model CM400 True RMS Clampmeter can measure AC current up to 400A without breaking the circuit by clamping around a single conductor. This saves time and the circuit will not be damaged. True RMS provides better accuracy when measuring non -sinusoidal or noisy waveforms. Additional measurements include Resistance, Capacitance, Frequency, Temperature, Diode Test, and Continuity. Measurements can read on the 4000 count backlit LCD. It has an Inrush current function that captures the instan taneous surge (inrush) current when power equipment is turned on. Features include: Peak voltage capture with min/max, NCV Detector with LED, Relative/DC zero function, Auto power off, and a built-in flashlight. Data Hold freezes the display for easy v iewing. CAT III-600V safety category. Includes Certificate of Traceability to N.I.S.T., 3 AAA batteries, test leads, Type K thermocouple probe, and carrying case. 1-year warranty.

We are also not able to ship to Post Office Box addresses. If you wish to ship to an address outside Canada or a military/government location, please contact your local Anixter sales representative to discuss your options.

In addition, offers Less-Than-A-Truckload “LTL” option for products that cannot be shipped via parcel shipping. For products that will be shipped via LTL, you will be provided with a set of Accessorials to select from to provide Anixter with additional shipping considerations, such as residential delivery, inside delivery, liftgate or limited access.

  • Residential Delivery - A residential delivery charge applies to shipments to a home or private residence, including locations where a business is operated from a home, or to any shipment in which the shipper has designated the delivery address as a residence.
  • Inside Delivery - When requested, freight carrier unloads shipments from or to areas that are not next to the trailer, such as shopping malls or office buildings. An elevator must be available to provide service to floors above or below the trailer.
  • Liftgate - Freight carrier provides liftgate service, if needed, to load and unload a shipment when loading/unloading docks are not available.
  • Limited Access Locations - A limited access location is a site where pickup or delivery is restricted or limited.

Shipping charges are calculated based on the shipping option you select, and is prepaid by you at the time of shipment.
