PD6701 Field-Mount Loop-Powered Feet & Inches Level Meter 

Instruction Manual

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 PD6701 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 SAFE-
TOUCH BUTTONS switch located on the connector 
board in the base of the enclosure. 

SafeTouch Button Operation 

To actuate a button, press and remove one finger  
to the window directly over the marked button area.  
Remove finger to at least 4 inches away from the 
window in between button activations. SafeTouch and 
mechanical buttons may be held to cycle through 
menus or digits in place of repeatedly pushing a  
button. 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 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. 

  If the cover has not been installed and secured 

tightly, it may take a moment for the SafeTouch 
buttons to properly self-calibrate when the cover 
is tightened. 

 

 

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.
