1621 Earth Ground Tester
Introduction
The Fluke 1621 Earth Ground Tester (the Product or Tester) is an easy-to-use
instrument for measuring the resistance to earth ground of a specified earth
ground electrode. The Tester can perform a 3-pole fall-of-potential test
conforming to IEC 61557-5. The Tester can also perform ac resistance testing.
To further simplify and increase the probability of an accurate measurement in
the 3-pole mode, the Tester measures the resistance of the probe and auxiliary
electrode to verify that they are within prescribed limits. The Tester also tests
for stray interference voltage (noise) and indicates if the value is too high to
take a proper measurement.
The Tester features a lighted LCD display, automatic shut-off, and a limits
mode for setting maximum resistance readings.
Unpacking
Refer to Accessories while unpacking the Tester and its accessories from the
shipping carton. Keep the packing material for future transport.
Check for missing parts and inspect the unit carefully for damage, like cracks,
dents, or bent parts. If items are missing or any physical damage is apparent,
call Fluke for assistance. Refer to Service for information on contacting Fluke.
Packing
Use only the original packing material to ship the Tester.

XW Warning
To prevent possible electrical shock, fire, or personal injury:
•Read all safety information before you use the Product.
•Do not alter the Product and use only as specified, or the
protection supplied by the Product can be compromised.
•Operating electrical devices implies that parts of the device
carry dangerous voltages.
•Assume that safe operation of the Product is not possible if
the device shows visible damage.
•Assume that safe operation of the Product is not possible if
the device has been exposed to unfavorable conditions (for
example, storage beyond the permissible climatic limits
without adaption to the ambient climate and dewing).
•Assume that safe operation of the Product is not possible if
the device has been exposed to major strain during transport
(for example, dropped from some height without visible
external damage).
•Do not connect Product to hazardous voltage.
•Do not open the battery compartment when leads are
connected.
•While a measurement is in progress, do not touch the earth
electrode, auxiliary electrode, or probe.

Software
To check the software version, set the rotary switch to OFF, and then press and
hold START and set the rotary switch to any On position (3 pole, 2 pole or
LIMIT). The software version displays.
LCD Display
The Tester features a lighted LCD display that shows measurement readings,
messages and icons. Refer to Figure 2 and Table 3 for descriptions of the
display’s icons.
To turn on the display light, press and hold DISPLAY for 2 seconds. To turn off
the light, press and hold DISPLAY again for 2 seconds. The light turns off
automatically after 30 seconds.

No. Description

RH,RS and REicons indicate the resistance type being displayed:
RH = Auxiliary electrode resistance
RS = Probe resistance
RE =Earth ground electrode resistance
Hazardous voltage. Voltage >30 V dc or ac peak might be
present.
ACTIVE icon indicates a measurement is in progress
Digits display measurement results and messages
keicon indicates reading value is in kilohms (x1000)
>LIMIT icon indicates measurement value exceeds the set limit or that auxiliary electrode resistance or probe resistance value
exceeds 199 ke
Wicon flashes if measurement value exceeds set limit or leakage
voltage exceeds 20 V
LO-BAT icon indicates battery voltage is low
U icon indicates the displayed measurement is stray interference
voltage (above 20 V)
Interference Detection
The Tester automatically checks for interference voltage (noise) fault voltage
above 20 V. Interference above 20 V greatly diminishes the accuracy of
measurements. If the Tester detects interference voltage above 20 V, the
measurement automatically stops, the Wicon flashes, the U icon displays, and
the value of the stray voltage displays.
Auto Shut-Off
The Tester has an auto shut-off feature that turns the device off after
10 minutes of inactivity. The Tester beeps to alert you that it is about to turn off.
To disable auto shut-off, simultaneously press and hold START and DISPLAY
while setting the rotary switch to any On position (3 pole, 2 pole or LIMIT). To
reset auto shut-off or to reset the Tester, turn off the Tester and then turn it on
again.
