Below is some model-specific information to help you locate your instrument response.

Centaur

Centaur digitizer technology is used within the Centaur standalone dataloggers, as well as all-in-one instruments such as the TitanSMA, TitanEA, MeridianCompact and MeridianPosthole. They use the same FIR filters, but offer different input (full-scale) voltage range options.

CentaurHighGain

The High Gain Centaur models have gains 4 times that of standard Centaur models. This is not reflected in the Centaur's user interface, so the operator needs to be aware that when selecting for example 40Vpp range, the High-Gain Centaur is really operating with a 10Vpp range. Centaur digitizer technology is used within the Centaur standalone dataloggers, as well as all-in-one instruments such as the TitanSMA, TitanEA, MeridianCompact and MeridianPosthole. They use the same FIR filters, but offer different input (full-scale) voltage range options.

EuropaT

The Taurus, Trident 305, Trident and EuropaT standalone dataloggers have identical responses with identically configured parameters. The Taurus and Trident 305 have selectable low (43.07 kohms) and high (9.4 Mohms) impedance options, but the Trident and EuropaT have a constant 43.07 kohm (low) input impedance.

HRD-24

The HRD-24 standalone datalogger has identical responses and parameters as the Orion.

MeridianCompact

Centaur digitizer technology is used within the Centaur standalone dataloggers, as well as all-in-one instruments such as the TitanSMA, TitanEA, MeridianCompact and MeridianPosthole. They use the same FIR filters, but offer different input (full-scale) voltage range options.

MeridianPosthole

Centaur digitizer technology is used within the Centaur standalone dataloggers, as well as all-in-one instruments such as the TitanSMA, TitanEA, MeridianCompact and MeridianPosthole. They use the same FIR filters, but offer different input (full-scale) voltage range options.

Orion

The Orion standalone datalogger has identical responses and parameters as the HRD-24.

Taurus

The Taurus, Trident 305, Trident and EuropaT standalone dataloggers have identical responses with identically configured parameters. The Taurus and Trident 305 have selectable low (43.07 kohms) and high (9.4 Mohms) impedance options, but the Trident and EuropaT have a constant 43.07 kohm (low) input impedance.

TitanEA

The dataloggers in the Titan SMA and Titan EA digital accelerometers are Centaur dataloggers with a single preamp gain choice of 1 (40 Vpp). The user may select the maximum full scale measurement range of +/-4g, +/-2g, +/-1g, +/0.5g +/-0.25g or +/-0.125g. This is applied to the internal Titan sensor, and so the Titan sensor response corresponding to the selected clip level should be used in conjunction with one of the digitizer responses below.
