PD6701 Loop-Powered Level Meter Instruction Manual
INTRODUCTION
The Vantageview PD6701 is a plastic field mounted loop-powered indicator
specifically designed for level applications in the harshest environmental conditions.
The meter displays level in easy to read and understand feet, inches, and fractions of
an inch; and a 20-segment tank level indicator. The lower display can show a custom
unit or tag, percent full, or a second scale for the 4-20 mA input used to indicate
volume.
The meter derives all of its power from the 4-20 mA loop. It is programmed using the
four SafeTouch
scaled with or without a calibration signal. The upper display will read up to
699 ft. – 11 15/16 inches. The alphanumeric volume/tag display will read up to
9,999,999. The alphanumeric display can also be programmed to show any
combination of numbers and letters up to seven characters long for use as
engineering units and/or the process identification tag. The backlight lets you see the
display under any lighting condition and can be powered from either the 4-20 mA
loop or from a separate DC power supply.
The enclosure is provided with two threaded conduit holes and integrated pipe or wall
mounting slotted flanges.

The display includes a 20-segment tank height indicator. This menu sets full and
empty values, in feet and inches, for the tank height indicator.
This value may differ from the 20 mA full-scale and 4 mA empty-scale values
programmed in the Scale menu. This is ideal for level transmitters that output less
than 20 mA at the maximum height of the tank or pit or more than 4 mA at the
minimum height.
As an example, when using a level transmitter that outputs 20 mA at 250 feet, the
tank height indicator may be set for 100 feet, 0 inches. At 100 feet 0 inches on the

OUTPUT
Alarm Output (
The PD6701 is equipped with an NPN open collector output that may be set up for
high or low alarm trip point based on the feet and inches level display (LEVEL) or the
volume scale (VOLUME). The output may be disabled by selecting OFF.
When the alarm is enabled for level and the alarm set point has been reached, the
level display will flash, accompanied by the bottom display alternating between
normal display and ALARM. A tank height indicator segment will flash at the level the
alarm is set to while the level indicator is at or above the alarm point.
When the alarm is enabled for volume and the alarm set point has been reached, the
bottom display will flash, alternating between its normal display and ALARM.
To set a high alarm, program the set point value to be greater than the reset point.
To set a low alarm, program the set point value to be less than the reset point.
To acknowledge an alarm, press the ENTER button once for acknowledge prompt
and a second time to confirm. Acknowledging an alarm will turn off the alarm output
and stop the display from flashing. The bottom display will continue to alternate
between its normal display and ALARM until the alarm condition is cleared.
The alarm status will show on the display even if the output is not wired.

FILTER
VOLSCAL
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 (MED), 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.
Volume Display Scaling (
Volume may be scaled as a function of the feet and inches level display. It may use
up to 32-point linearization. The multi-point 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.
To display the volume, select a bottom display including the volume display in the
Display menu as shown in Configuring the Lower Display (DISPLAY) on page 24.
To scale the volume display, enter the level in feet and inches for input 1, and then
the corresponding volume display value. Do the same for input 2.
)
)
After entering the display 2 value, confirm the new volume scale by pressing ENTER
at the Save menu.

Internal Calibration (
There is no need to recalibrate the meter when first received
from the factory. The meter is factory calibrated prior to
shipment. The calibration equipment is certified to NIST standards
The internal calibration is the meter’s master calibration that makes scaling the meter
without a signal source possible. Use of a calibrated signal source is necessary to
perform an internal calibration of the meter. Check calibration of the meter at least
every 12 months. Incorrect calibration will affect the ability of the meter to properly
read, scale, and display the input.
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 calibration procedure.
)
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 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 mA. Apply a 20.000 mA signal and
press ENTER. The display flashes for a moment while the meter is accepting the
signal.
Calibration Error Message (
An error message indicates that the calibration process was not successful. After the
error message is displayed, the meter will revert to the 4 mA calibration menu. 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.
