12 Clamp-on Ground Resistance Tester Model 6416
Item
Description
8 Signal indicating potentially hazardous voltage. Blinks when the
contact voltage exceeds 50 V.
9 Alarm threshold high/low indicator (operational use or configuration):
▲ Alarm threshold high indicator.
AL Alarm threshold adjustment mode or Alarm function.
▼ Alarm threshold low indicator.
10 Alarm threshold display:
- Display of one of the alarms (1000-count display) with units.
- These three digits are also used when configuring the time
display mode.
(A for A.M., P for P.M. or 24H) in SET-UP (see § 4.4, menu #8).
11 Unit of the alarm displayed. The alarm can be defined on a
resistance impedance, voltage, or current, depending on the
measurement chosen (
Ω+A or A).
- A: Current measurement alarm.
-
Ω
: Resistance measurement alarm.
- V: Voltage measurement alarm.
12 Unit of the central measurement display:
- V: Contact voltage measurement unit.
-
Ω
: Impedance measurement unit. Symbol used for impedances
at the measurement frequency, for impedances referred to the
network frequency, or for the resistive component.
13 Unit of the top measurement display:
- mH: Loop inductance measurement unit.
- mA or A: Current measurement unit.
14 Upper display: 4000-count current measurement and 500-count loop
inductance measurement (Advanced mode).
15 Battery charge indicator:
- Not displayed: Batteries charged.
- Blinking: Batteries low. The device remains functional, but the
batteries will have to be replaced soon.
- Steady: Batteries discharged. The display indicates Lo bat. It is
not possible to make measurements, read records, or configure
parameters.
16 Continuous operation of the clamp (Auto Power OFF disabled).
Selection of Auto Power OFF mode is made in SET-UP (see § 4.4,
menu #3).
