Product Usage Instructions
Low Frequency Measurements
When a low-frequency measurement parameter reaches its recording
condition, the MSR 165 starts recording all activated parameters
and stops when the record limit drops below the preset value.
Shock Measurements
For shock measurements, the MSR 165 saves the last 32
measurements when the recording condition is fulfilled and saves
the next 100 measurements when the condition is no longer
fulfilled.
Vibration Measurements
When setting up for vibration measurements, ensure the
underlying acceleration due to gravity is not considered. Select a
measurement rate and record limit for each axis for accurate
readings.
FAQ
Q: What is the alarm limit for shock measurements?
A: The alarm limit is automatically set to the record limit for
shock measurements.
Q: How can I cancel an alarm during vibration
measurements?
A: The alarm can only be canceled if enabled through the
specified steps in the manual (refer to page 24 and 26).

Introduction
The MSR 165 allows high frequency acceleration measurements at max. 1600 HZ (±15%) or high frequency analogue measurements at max. 1024 Hz to be made. High frequency acceleration measurements are used for shock and vibration measurements. The remaining low frequency measurement parameters are measured at max. 1 Hz and a common measurement rate is automatically used. Conditional recording of measurement parameters For high and low frequency measurements, recording conditions can be selected. The measurement parameters are only recorded when the recording condition has been met. The recording conditions are divided into high and low frequency measurements as follows: Note: In the case of shock measurements the recording condition is known as the “Threshold” whilst for all other measurements the term “Record limit” is used.
a) Low frequency measurements When one of the low frequency measurement parameters reaches its recording condition (record limit), the MSR 165 starts to record all of the activated low frequency measurement parameters. It stops recording when the record limit drops below the pre-set value. The alarm limit can be displayed in Viewer (see also ->26).
b) High frequency measurements When one of the high frequency measurement parameters reaches its recording condition (threshold, record limit), the MSR 165 starts to record all 3 acceleration axes or all 4 analogue inputs. In the case of high frequency measurements the MSR 165 also records the last 32 measurement parameters before the threshold value is reached. If the recording condition is no longer fulfilled the MSR 165 still records the next 100 measurement parameters (see figure on next page).

Shock measurements
The MSR 165 shock measurement function was specially conceived for the monitoring of transportation conditions. Its power consumption when making shock measurements is lower than when measuring vibrations. In addition to registering shocks, temperature, humidity and ambient pressure can also be recorded. Configuring the MSR 165 for shock measurements: The MSR 165 can only be configured for shock measurements using the Shock program (msr165_shock). Open the Shock program and click Open assistant. Follow the assistant’s on-screen instructions. By entering the recording condition (threshold) you can define which shocks are recorded (max. +/- 15 g,

Notes on high frequency measurements
Circular buffer mode If circular buffer mode is deactivated and the MSR memory is full,
VORSICHT recording will be paused. In order to avoid this, activate circular buffer mode (see ->24 or Shock assistant step 4).
Reader ->33 During data recording it is not possible to read measurement parameters from the MSR 165.
Limitations Shock measurements, vibration measurements and high frequency analogue measurements cannot be recorded simultaneously. For simultaneous data recording multiple MSR 165 units should be used.
Problems and how to solve them
Problem
The marker function cannot be selected.
Solution
Deactivate Start and stop by push-button. See ->24 or Shock assistant step 3
Notes on temperature measurements
In addition to pressure, the pressure sensor also records the internal temperature T(p). In addition to humidity the humidity sensor also records the internal temperature T(RH). These internal temperatures are utilised for the temperature compensation of the sensors.
