LEDs.
A. Resistance Range LEDs: Indicates the selected
resistance at which you would like to test.
B. Program LED: Will illuminate when the monitor is
readyto be calibrated or programmed. When the LED is
off, the monitor is in standby mode / normal operation.
C. Set Buttons: Used to calibrate and program the
monitor.
Installation (See Figure 6)
I. Remove the monitor from the carton and inspect for
damage.
II. Determine the mounting location of the Multi-Ground
Continuous Monitor. It is normally installed under a
bench top toward the front edge of a workstation
where the LEDs are clearly visible.
III. Install the monitor using the anges and provided
screws (see Figure 5).
IV. Insert the banana plug of the included right angle
ground wire into the banana jack labeled “GROUND
REFERENCE” on the monitor.
Figure 5. Mounting the Multi-Ground Continuous
Monitor.
V. Insert the other end of the ground wire to electrical
ground. The included ring terminal may be used for
this connection.
VI. Install the included Multi-Ground Hub Kit near the
monitor. Visit Desco.com and see Drawing 09837 for
installation instructions.
VII. Attach the ring terminal end of the included 10’ long
ground wire to the Multi-Ground Hub.
VIII.Insert the tinned wire end of the same ground wire
into the terminal labeled “GND-H” on the monitor.
CONNECTING ITEMS TO THE MONITOR
The Multi-Ground Continuous Monitor can be set to
monitor the resistance of worksurfaces, tools, carts, and
accessories using the test ranges of 1 ohm, 1 megohm,
10 megohms, and 35 megohms. It can monitor a com-
bination of 8 items. The following procedure requires
items that are not included with the Multi-Ground Con-
tinuous Monitor. Use terminals 1-8 on the back of the
monitor to connect the item to be monitored to the Multi-
Ground Continuous Monitor. One ground wire must be
connected to the monitor and the item to be monitored.
Another ground wire must be connected to the item to be
monitored and the Muti-Ground Hub (see
Figure 6).
CONNECTING TO THE RELAY TERMINALS
The Multi-Ground Continuous Monitor can output its test
results to a light xture or programmable logic controller
(PLC) using the terminals labeled as “RELAY 1” and
“RELAY 2.” Refer to Figure 6 and the following
informationto connect light towers or programmable logic
controllers to the Multi-Ground Continuous Monitor.
Terminals 1 & 2 = normally open
Terminals 2 & 3 = normally closed

Operation
SETTING TEST RANGES
Hold down the SET 1 and SET 2 buttons until the
monitor beeps. The GROUND 1 LED on the face of the
monitor will begin to blink indicating that its settings are
being modied. The PRG LED will illuminate to indi-
cate that the monitor is in Programming Mode. The test
range is set if its corresponding LED is illuminated. Use
the SET 2 button tocycle through the test ranges. If you
would like to turn the ground channel off, press SET 2
until none of the resistance range LEDs are illuminated.
The LED for the selected channel will illuminate red.
