7.3.42 Remote Monitor Low
Remote Monitor Low ( Sine Check Stop Code )
This code indicates that the rear inputs are configured to abort the test below a predetermined level,
and this level has been reached.

7.3.43 Resonance Min Drift Limit
Resonance Min Drift Limit ( Sine Stop Code )
This code indicates that the resonance frequency has drifted below the lower limit specified in the
Sine Resonance Control dialog box. Typically this is a result of failure (e.g. breakage) of the
product being tested.
7.3.44 Resonance Max Drift Limit
Resonance Max Drift Limit ( Sine Stop Code )
This code indicates that the resonance frequency has drifted above the upper limit specified in the
Sine Resonance Control dialog box. Typically this is a result of failure (e.g. breakage) of the
product being tested.
7.3.45 Run System Gain Limit
Max Run System Gain ( Sine Stop Code )
This code indicates that the maximum allowable voltage/acceleration ratio was reached while the test
was running. This error typically results from having a disconnected accelerometer, not having the
amplifier turned on, or having the amplifier gain level turned to a low setting.
If the accelerometer and amplifier are all properly connected, it may be that the running Max System
Gain limit for this test is too conservative. This parameter is set in the
Sine Limits dialog box.
Typically the maximum system gain allowed while the test is running should be about 125% to 150% of
the maximum voltage/acceleration ratio required over the entire frequency range of the test.
The Max System Gain limit is a safety limit used to prevent the output from reaching excessive levels
while the test is running, in such cases as when the accelerometer is not connected or has fallen off
the test product. You can disable this safety feature (
not recommended!!! ) by selecting a high gain
level (e.g. 10 Volts/G) for the Max System Gain parameter.
7.3.46 Startup System Gain Limit
Max Start System Gain ( Sine Stop Code )
This code indicates that the maximum allowable voltage/acceleration ratio was reached when starting
the test. This error typically results from having a disconnected accelerometer, not having the amplifier
turned on, or having the amplifier gain level turned to a low setting.
If the accelerometer and amplifier are all properly connected, it may be that the starting Max System
Gain limit for this test is too conservative. This parameter is set in the
Sine Limits dialog box.
Typically the maximum system gain allowed during the test startup should be about 125% to 150% of
the expected voltage/acceleration ratio required at the starting frequency.
