230VAC Wall adapter used as a battery eliminator to power compatible instruments without using battery power. Output plug dimensions are: length: 10.5mm, outer diameter: 4mm, inner diameter: 1.5mm

Model LC29B，DMM Carrying Case

Light weight, durable Cordura nylon Protects your instruments

Made in the U.S.A.

Room to hold your test leads

Approximate Internal Dimensions: 4"x2.5"x8" (102x64x203mm)

Model TL LCR，Test leads for handheld LCR meters (Sheathed)

Includes one red and one black lead

5" Long sheathed banana to alligator clip

Short length allows for accurate component measurements

Used with LCR Meters and Capacitance Meters

Model TL8KC1，4 Terminal shielded Kelvin test lead

The TL8KC1 is a Kelvin test lead that is useful when measuring leaded capacitors, inductors, and resistors. Cable length is approximately 16 inches (40.64 cm). When used with the 880, the guarded lead reduces the effect of lead impedances and contact resistance thus minimizing measurement errors and improving accuracy especially in the lower impedance range. The TL8KC1 is an included accessory with the model 880.

SMD Tweezer Probe

Model TL8SM

The TL8SM is a tweezer probe that is useful when measuring surface mount capacitors, inductors, and resistors. Cable length is approximately 16 inches (40.64 cm). When used with the 880, the guarded lead reduces the effect of lead impedances and contact resistance thus minimizing measurement errors and improving accuracy especially in the lower impedance range. The TL8SM is an included accessory with the model 880.
