5.0 C HANGING M EMORY P ARAMETERS
The following parameters are set at the factory:
• Decimal point: autorange
• Internal timer: continuous
• External trigger edge: L-H (Lo to Hi)
These parameters can be changed in the field to facilitate different situations.
To change any of the above parameters, follow these steps:
1. Turn power on.
2. Make sure that INT lamp is on. If not, press “SIG” until it turns on.
3. Change the desired memory parameter:
a. To change the decimal point:
• Press “÷2” and “-“ at the same time for approximately 2 seconds until
display alternates between —1— and 0.0.
• Press “+”. The display will freeze and show 0.0.
• Change decimal point accordingly by pressing “+”. If 0.0 is selected
the decimal point is in the autorange mode. If 0 is selected the decimal
point is eliminated throughout the entire range.
b. To change the internal timer:
• Press MODE. The display will alternate between —2— and 0.
• Press “+”. The display will freeze to 0.
• Use the setter to set timer anywhere between 1 and 120 minutes.
