# PC - Pulse Count

Tools
STR

This step monitor is only available for the following tools:

- ETV-STR61-100-13

- ETV-STR61-70-13

- ETV-STR61-50-10

Before using the Pulse Count step monitor, the Low Reaction Strategies license must be installed on the controller.

This monitor measures the number of pulses and confirms if it is between the pulse count low limit and pulse count high limit.
If the torque trigger level is set, the check starts as soon as the measured torque is above the torque trigger level.

If running a tightening step with Pulse Count step monitor, use the necessary PulseDrive socket/adapter.
If the tightening step runs without the PulseDrive socket/adapter, all the tightenings are NOK. The step error “PulseDrive socket/adapter not detected” shows for no PulseDrive socket/adapter.

Parameter | Description
--- | ---
Pulse Count High Limit - n+ | The Pulse Count limits are used to determine if the measured number of pulses is OK or NOK. The measured number of pulses is OK if it is between the pulse count low limit and pulse count high limit. The measured number of pulses is NOK if: It is higher than the pulse count high limit. It is lower than the pulse count low limit. The trigger torque level is not reached. Pulse count high limit must range from 1 through 9999999. It must be greater than or equal to the pulse count low limit. Pulse Count High Limit text box can be empty.
Pulse Count Low Limit - n- | The Pulse Count limits are used to determine if the measured number of pulses is OK or NOK. The measured number of pulses is OK if it is between the pulse count low limit and pulse count high limit. The measured number of pulses is NOK if: It is higher than the pulse count high limit. It is lower than the pulse count low limit. The trigger torque level is not reached. Pulse Count Low Limit must range from 1 through 9999999. It must be lower than or equal to the Pulse Count High Limit. Pulse Count Low Limit text box can be empty.
Torque Trigger - Tt | Torque Trigger must range from 0 through the maximum torque of the tool. Torque Trigger text box can be empty.
