SETUP AND PROGRAMMING
There is no need to recalibrate the meter for milliamps
when first received from the factory.
The meter is factory calibrated for milliamps prior to
shipment. The calibration equipment is certified to NIST
standards.
Overview
Setup and programming is done through the infrared through-window SafeTouch
buttons, or using the mechanical buttons when uncovered. There are two slide
switches located on the connector board. One is used to select backlight power (if
equipped) and the other is to lock or unlock the SafeTouch
®
buttons.
SafeTouch® Buttons
®
The PD6700 is equipped with four sensors that operate as through-window buttons
so that it can be programmed and operated without removing the cover. These
buttons can be disabled for security by selecting the LOCK setting on the switch
located on the connector board in the base of the enclosure. To actuate a button,
press one finger to the window directly over the marked button area. When the cover
is removed, the four mechanical buttons located next to the sensors are used. The
sensors are disabled when a mechanical button is pressed and will automatically be
re-enabled after 60 seconds of inactivity.
The SafeTouch
®
buttons are designed to filter normal levels of ambient interference
and to protect against false triggering, however, it is recommended that the
SafeTouch
®
buttons be disabled (slide switch to LOCK) if there is an infrared
interference source in line-of-sight to the display.
SafeTouch
®
Button Tips:
• To remove cover with power applied (safe area only), or to clean the window,
select SERVICE in the main menu before opening the cover. This will temporarily
disable the SafeTouch
®
buttons for 60 seconds to prevent inadvertent use. Use
the mechanical buttons while the meter is open.
• To the extent possible, install the display facing away from sunlight, windows,
reflective objects and any sources of infrared interference.
• Keep the window clean.
• Tighten the cover securely.
• Use a password to prevent tampering.
After all connections have been completed and verified, apply power to the loop.

Advanced Function Selection (
The Advanced Function menu is used to select the advanced function to be applied
to the input: linear, square root, programmable exponent, or round horizontal tank
volume calculation. The multi-point linearization is part of the linear function selection.
Meters are set up at the factory for linear function with 2-point linearization. The linear
function provides a display that is linear with respect to the input signal.
Multi-Point Linearization (
Up to 32 linearization points can be selected under the Linear function. The multipoint linearization can be used to linearize the display for non-linear signals such as
those from level transmitters used to measure volume in odd-shaped tanks or to
convert level to flow using weirs and flumes that require a complex exponent. These
points are established via direct entry (SCALE) or with an external calibration signal
(CAL).
Manual Entry (
Manual entry of the linearization data is done once the number of points has been
selected (noPtS). Input signal levels (InP 1-32) for up to 32 points, along with the
desired/corresponding meter reading (dSP 1-32) should be entered for each linearization point. See Figure 6 on page 30.
)
)
)
External Calibration (
Linearization data can be entered using a known accurate signal source (InP 1-32)
and then entering the desired/corresponding meter reading (disp 1-32) for that
input signal level. See Figure 6 on page 30.
)
Important Navigation Note:
After entering the last display value, the linearization entries must be saved (SAUE?)
before they go into effect. You may move past this selection using the Up arrow key if
you need to go back and correct an earlier entry. Once confident in the entries however, the user must navigate back to the Save menu screen (SAUE?) and press the
Enter key to save the changes.

FILTER
Low-Flow Cutoff (
The low-flow cutoff feature allows the meter to be programmed so that the oftenunsteady output from a differential pressure transmitter, at low flow rates, always
displays zero on the meter. The default cutoff is zero to prevent negative readings,
but this may be overridden to allow them.
The cutoff value may be programmed from 0 to 99999. Below the cutoff value, the
meter will display zero. Selecting either square root or programmable exponent will
set the cutoff value to 0. Program the cutoff value to 0 to disable.
Input Signal Filter (
The noise filter is available for unusually noisy signals that cause an unstable
process variable display. The noise filter averages the input signal over a certain
period. The filter level can be set to low (LO), medium (nmed), high (HI), or off (OFF).
The higher the filter setting, the longer the averaging time and so the longer the
display may take to find its final value.
The filter contains a noise filter bypass feature so that while small variations in the
signal will be filtered out, large, abrupt changes to the input signal are displayed
immediately.

Internal Calibration (
There is no need to recalibrate the meter for milliamps when first
received from the factory.
The meter is factory calibrated for milliamps prior to shipment.
The calibration equipment is certified to NIST standards.
The internal calibration allows the user to scale the meter without applying a signal.
The use of a calibrated signal source is necessary to perform the internal calibration
of the meter. Check calibration of the meter at least every 12 months.
Notes:
The signal source must have a full-scale accuracy of 0.002% or
better between 4 and 20 mA in order to maintain the specified
accuracy of the meter.
Allow the meter to warm up for at least 15 minutes before
performing the internal calibration procedure.
The Internal Calibration menu (ICAL) is part of the Advanced features menu.
Press and hold the MENU button for 5 seconds to enter the Advanced features
menu. Press the Up arrow button to scroll to the Internal Calibration menu (ICAL) and
press Enter.
)
The meter displays 4.000 mA. Apply a 4.000 mA signal and press Enter. The display
flashes for a moment while the meter is accepting the signal.
After the signal is accepted, the meter displays 20.000 mA. Apply a 20.000 mA signal
and press Enter. The display flashes for a moment while the meter is accepting the
signal.
Error Message (
An error message indicates that the calibration process was not successful. After the
error message is displayed, the meter will revert to input 2 calibration settings. The
error message might be caused by inadvertently leaving the signal at the previous
level or not maintaining the minimum span. Press the Menu button to cancel the
current calibration process if necessary.
Information (
The Information menu (INFO) is part of the Advanced features menu. It shows
software identification number and version number. To determine the software
version of a meter:
Go to the Information menu (INFO) and press Enter button.
Continue pressing Enter to scroll through the software release number and software
version.
)
)
Following the information display, the meter will exit the Advanced features menu and
return to run mode.
