ANDO VMG-1000 Highmegohm Meter

The Ando VMG-1000 Highmegohm Meter is designed to measure the insulation resistance of high-insulation materials, Up to 2 x 10^10 M-ohm of insulation resistance can be measured. This instrument can also be used as a highly sensitive ammeter to measure current in the range of 5 x 10^-14 to 2 x 10^-5 A. The VMG-1000 incorporates a timer for setting a specific amount of absorption current (charging current, etc.) after the measurement voltage has been applied, and also a GO/NO-GO decision function by means of a comparator, which enables initial setting of a measured value. This facilitates repeated measurements under the same conditions, convenient for component inspection. Use of this instrument will greatly raise efficiency not only in research and development work, but also in assembly line inspections. Specifications. Insulation resistance measurements: 5 M-ohm to 2 x 10^10 M-ohm, in 8 ranges. Accuracy: Meter needle range at 1/3 to 3/4 of full scale (Current scale is 7 to 15 uA), ± 4.5 % for 10^2 to 10^7 M-ohm range, ±8% for 10^8 M-ohm range, ± 10% for 10^9 M-ohm range. Short circuit current: Less than 1 mA. Current measurement: 5 x 10^-8 uA to 20 uA, in 8 ranges. Accuracy for full scale: ± 2 % for 1 to 10^-4 uA range.

*This is a Web introductory price for one calibration of the ANDO VMG-1000. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). Zero dBm equals one milliwatt. A 3 dB increase represents roughly doubling the power, a 3 dB decrease, the power is reduced by about one half.

Millimeter-wave is a term that generally refers to frequencies of 26.5 GHz and above. That is where signal wavelengths fall below approximately 10 mm, and thus the terminology changes from centimeters to millimeters.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, remains fixed with the passage of time or with varying environmental conditions.
