FAQ
Q1: Can the TK81 be used to calibrate proximity probes or accelerometers?
A1: No. It is primarily for velocity-type Seismoprobes. Use the TK3-2e for proximity probes and specialized shakers for accelerometers.
Q2: Does the TK81 require professional recalibration?
A2: Yes. It should be sent to a certified lab annually to maintain signal accuracy.
Q3: What is the benefit of using the TK81 over a generic signal generator?
A3: It is impedance-matched for Bently Nevada sensors, providing a realistic signal identical to an actual vibrating Seismoprobe.
Q4: How long does the battery last during field use?
A4: Typically a full day of testing, but check the battery before entering hazardous or remote sites.
