If multiple instruments need a ground reference the four positions of TB2 can serve as those ground points (assuming the JP17-JP20) jumpers are intact. If more than four grounding screws are needed then a custom wire from TB2 to a separate terminal block can allow for more grounding screw positions.

REJ FREQ 60HZ
50HZ
REJECTION FREQUENCY – be sure that this selection
agrees with the line voltage frequency.
HF REJ ENABLE
DISABL
HIGH FREQUENCY REJECTION – This selection
allows high frequency noise rejection. It is used to quiet
noisy pens or PV.
ATTENTION
For fast processes it will cause
additional lag.
RELHUMID NO
YES
RELATIVE HUMIDITY – allows you to activate or
deactivate the RH calculation algorithm.
· You must select 100RH input type for two inputs to
measure RH. It requires two 100-ohm RTD inputs so
INPUT 2 must be enabled for this prompt to appear.
· Also, you must select RH for “PEN2IN” which
represents the “wet bulb” temperature when input 2 is
selected.
ATMPRES 590 to 800 mmHg ATMOSPHERIC PRESSURE COMPENSATION – This
prompt only appears if you select “YES” at “RELHUMID”
prompt previously. Select the desired compensation.
DEVIATION
NONE
SETPNT
CHAN1
DEVIATION – selects deviation recording action.
· NONE – No deviation recording
· SETPNT – Records deviation from setpoint
· CHAN1 – Pen 1 records the difference between Input
1 and Input 2.
DEVSETPT –999.0 to 9999 DEVIATION SETPOINT VALUE – sets the desired
deviation setpoint value for deviation recording.
· This prompt only appears if “SETPNT” was selected
at prompt “DEVIATION” previously
