Attach GND line to known good ground

Attach monitor line(s) (G1, G2, G3) to ground that has 

been determined to use. Do not plug any wires into 

those ground monitor inputs that will be unused.

Press and hold the Set button using a pin. While the 

button is pressed inward, plug in the AC Adapter and 

then release the Set button.

Wait then for approximately 30 seconds. The Ground 

Man Plus Ground Monitor will beep during this time. 

After this time, the monitors will produce one beep and 

will automatically disable the lines to which nothing was 

connected. This procedure can be repeated whenever a 

change in the number of ground lines being monitored is 

required.

Enabling and Disabling Audible Alarm 

The audible alarm can be enabled or disabled by 

momentarily pressing a recessed miniature push button 

Set switch located on the back of the unit while the 

monitor is powered on. Use a paper clip to press the 

switch.

Setting Impedance Alarm Levels

By default, the Ground Man Plus Ground Monitor factory 

set to a 10 ohms alarm level.
If this specification needs to be changed, the following 

procedure sets the impedance alarm level for all 

channels (G1, G2, G3).
Repeat the steps above in description section. 
Right after the beeps stop; continue pressing the Set 

button until the impedance level is matched as shown in 

the table on the next page.
When the beeping stops, the four left-most LEDs (as 

shown in the photo on next page) allow for setting of 

resistance value. G1 & G2 red LEDs are upper location 

and G1 & G2 green LEDs are lower. Select the ground 

impedance value by pressing the Set button to advance 

the resistance limit. Turn the LEDs on or off as indicated 

in the table on the next page.
Not pressing the Set switch for about seven seconds 

after selecting causes the limit value to be saved and 

normal operation started.

Alarm Level

Verification Check 

Verification of G1, G2 and G3 monitoring.

1.  Prepare the 

CTE701

 Workstation Monitor Checker.

2.  Disconnect the wire connected to G1, G2 and G3

3.  Connect the ground input of the checker to the ground 

connector of the Ground Man Plus Ground Monitor. 

Set the checker to a proper resistance alarm level 

(see the CTE701 Workstation Monitor Checker User 

Guide).

4.  Connect the red wire tip of the checker to the device 

terminal (G1, G2 and G3)

5.  Press the Metal Ground Fail button on the checker. 

The red LED of either G1, G2 or G3 should remain on.

6.  Press the Metal Ground Pass button on the checker. 

The green LED of either G1,G2 or G3 should turn 

green.

7.  Repeat these steps for all enabled ground monitoring 

inputs.
