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 traceable 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 and the other is to lock
or unlock the SafeTouch Buttons.
After all connections have been completed and
verified, connect the ribbon cable to the display
module, fasten the display module to the base, install
enclosure cover, and then apply power.
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 and exposing the electronics to the
environment. 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.
SafeTouch Button Tips and
Troubleshooting
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 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.
•
SafeTouch buttons will not work if two or more
buttons are detected as being pressed
simultaneously. As a result, be careful to avoid
triggering multiple buttons or reaching across one
button
location to press another.
