OPERATING INSTRUCTIONS TREND SERIES
GAIN ADJUST
The GAIN ADJUST control is a small multi-turn control located on the extreme left of each channel board.
This control is used to adjust the instrument to display the proper CAL (calibration) number on the digital
meter(s).
1. Push CALIBRATION SWITCH to the ON (back)
position. This switch puts the CAL resistor
(simulated load) across the sensor for that channel.
2. Set the GAIN ADJUSTMENT
If the press has been calibrated, use the CAL
numbers that are recorded for each channel. If the
press has not been calibrated, use 50 as a
temporary cal number.
Watch the digital meter and turn the GAIN ADJUST
control until the meter displays the correct CAL
number. Repeat for all channels.
3. Turn AUTO ZERO on by moving the AUTO
ZERO switch to the ON (forward) position. Pull
CALIBRATION switch to the OFF (forward) position
to remove simulated load.
4. Set MONITOR/CALIBRATE switch back to
“MONITOR” position.
During normal operation, Auto Zero and Calibration switches must be in the forward position.
Monitor/Calibrate switch must be in Monitor position.
