Operation

Operating the TLM

Once the TLM  has been calibrated it is ready for 
continuous use.  To ready the TLM  for load conversions, 
follow these four steps: ( Figure 9)

Figure 9

Step 1: 

Enter the run mode by switching from CAL 
to RUN.

Step 2: 

Make sure that the GAIN SET/ZERO switch 
is set to ZERO.

Step 3: 

Insure that the external probe signal is 
turned on before the load is generated 
and off after the operation is complete.  If 
the logic of the probe is reversed, use the 
N.C./N.O. switch to invert the probe signal 
logic or adjust the probe accordingly.

Step 4: 

Set the TRACK/PEAK switch to the desired 
mode.  While in TRACK mode each 
channel’s output will follow the loading 
on the sensor as the load on the machine 
increases and decreases.  In PEAK mode, 
the output will increase to the highest load 
level and remain at that voltage until the 
probe is released.
