M3 Digital LCRZ Meter Features
|
 |
The M3 Digital LCR Meter features:
- The M3 Digital LCRZ meter is a multi-frequency impedance measuring instrument capable of measuring resistance, capacitance, inductance or transformer parameters from 1 milliohm to 1 Megohm impedance. The LCRZ meter is controlled by a high speed microcontroller with embedded logic that operates the display, keypad, as well as setting measurement conditions and performing calculations.
- Measurement Modes (automatic or manual) and display ranges:
Inductance (L) + Q (quality)
L: 0.01uH to 99.99H Q: 0.001 to 100
Inductance (L) + AL
L: 0.01uH to 99.99H AL: L/N2 (N set by user from 1 to 999)
Capacitance (C) + D (dissipation)
C: 0.001pF to 99999uF D: 0.001 to 10
Resistance (R) + Q
R: 1 milliOhm to 99.9 MegOhms Q: 0.001 to 100
Absolute Impedance (|Z|) + Theta (Phase Angle)
|Z|: 1 milliohm to 99.9 MegOhms Theta: -180 to +180 degrees
Resistance (R) + X (reactance)
R: 1 milliOhm to 99.9 MegOhms X: 1 milliOhm to 99.99 MegOhms
Conductance (G) + B (Susceptance)
Transformers: Turns Ratio (N)+ Phase Angle, Power transformer Primary/Secondary voltages (Vp+Vs), and Mutual Inductance (M)
Varactor Diodes (with optional test fixture)
