equipment which shall within one (1) year after delivery of such instrument
or other article of equipment to the original purchaser be returned intact to
it, or to one of its authorized service centers, with transportation charges
prepaid, and which its examination shall disclose to its satisfaction to
have been thus defective; this warranty being expressly in lieu of all other
warranties expressed or implied and of all other obligations or liability on its
part, and Simpson Electric Company neither assumes nor authorizes any
other persons to assume for it any other liability in connection with the sales

Company factory or authorized service centers, nor which has been subject
to misuse, negligence or accident, incorrect wiring by others, or installation
or use no in accord with instructions furnished by the manufacturer.
This instrument is designed to prevent accidental shock to
the operator when properly used. However, no engineering
design can render safe an instrument which is used
carelessly. Therefore, this manual must be read carefully
and completely before making any measurements. Failure
to follow directions can result in a serious or fatal accident.

1. Safety
1.1 Warning Symbols
This manual provides details of safe installation and operation
of the meter. Safety may be impaired if the instructions are not
followed. Labels on individual meters give details of equipment
ratings for safe operation. Take time to examine all labels on the
meter and to read this manual before commencing installation.
CAUTION WARNING
Refer to Operating Manual Danger Risk of Electric Shock
Figure 1-1 Safety Symbols
WARNING
The meter contains no user serviceable parts. Installation and
commissioning should be carried out by qualified personnel
1.2 Maintenance
The equipment should be maintained in good working order.
Damage to the product should be repaired by the manufacturer.
The meter may be cleaned by wiping lightly with a soft cloth. No
solvents or cleaning agents should be used. All inputs and supplies
must be isolated before cleaning any part of the equipment.

2. Meter Operation
2.1 Measurements
The GIMA makes use of a high speed micro-processor and an
Analogue to Digital converter to monitor input signals from three
independent phases. Each phase voltage, current and power (kW)
are measured directly and a number of other parameters derived
from these in software. The measurement process is continuous
with all six signals scanned simultaneously at high speed. Unlike
many other sampling systems, which sample one phase after
another, this ensures that all input cycles are detected. Distorted
input waveforms, with harmonics to the 30th are therefore detected
accurately.
Derived parameters are calculated and displayed once a second,
scaled by user programmed constants for current and voltage
transformers.
Instantaneous power parameters are integrated over long time
periods providing a number of energy registers. System frequency
is detected by digital processing of the phase 1 voltage signal.
2.1.1 Balance Current Measurements
The rms. value of the instantaneous sum of the three phase
currents is available on some GIMA meter types. The total current
in a three phase system may be represented as :
Ibal = I1+ I2+ I3= ILEAK + In
ILEAK represents any current leaving the system (e.g. Leakage to earth)
Inrepresents current in the neutral (4 wire systems only)
Note: In 3 phase 3 wire systems the GIMA must be wired using
3 current transformers as shown in fig. 4-3 for balance current
measurement to be made.

2.1.2 Time Averaged Amps/Volts (T-Avg)
Average values of volts and Amps are calculated over a user
programmable time period (10 - 2500 seconds). The displays show
the averages for the most recent time period ending at the time
the display was last updated. The average period is continuously
updated as time progresses.
The largest value of each T-Avg parameter is recorded, saved to
non-volatile memory and displayed as Pk hold T-Avg. These peak
values may be reset by the user.
Each Average-Period is split into 10 sub-periods. The average
values of volts and amps are measured during each sub-period and
stored in an array. The latest sub-period values replace the oldest
in the array as time progresses. The T-Avg values are calculated
as the mean of each corresponding array. The display is updated
with the latest T-Avg parameters at the end of each sub-period
(every Average-Period/10 seconds).
2.1.3 Maximum Demand Power (MD)
Average values of kW, kVA and kvar (if fitted) are calculated over
a user programmable time period (1 - 60 minutes). The displays
show the averages for the most recent time period ending at
the time the display was last updated. The demand period is
continuously updated as time progresses. These parameters are
referred to as Maximum Demand Powers.
The largest value of each MD parameter is recorded, saved to non-
volatile memory and displayed as Pk hold MD. These peak values
may be reset by the user.
Each MD-Period is split into 30 sub-periods. The average power
values are measured during each sub-period and stored in an
array. The latest sub-period values replace the oldest in the array
as time progresses. The MD powers are calculated as the mean
of each corresponding array. The display is updated with the latest
MD values at the end of each sub-period (every MD-Period/30
seconds).

GIMA Option Links
1. Option Links
WARNING
Risk of Electric Shock!
Isolate the instrument supply and all inputs before accessing the option links
Four option links may be accessed on the rear of the GIMA display
PCB. Meters are normally shipped with all these links fitted.
*Not customer programmable. Contact Simpson before changing.*
1.1 Option Link Detection
For safe operation the instrument supply and all inputs must be isolated before
accessing option links. The link settings are only detected during power-up of the
auxiliary supply to the meter
2. Enable Programming Menu (Link1)
If this link is removed the user may not gain access to the programming menu
using the front panel keys. For further details of programming the GIMA refer to the
meter operating instructions.
3. Disable Reset Energy (LINK2)
If this link if fitted the Energy Registers may be reset by:
Press Pto display any energy register
Press AMP and VOLTS together and hold until energy resister resets to zero
(approx 5S).
If this link is removed the Energy Registers may not be reset
NOTE: Once reset to zero the accumulated energy readings may not be recovered.
4. Disable Reset Peaks (LINK3)
If this link is removed the peak hold and peak demand values may be reset by:
Select any display page showing a Peak Hold or Peak Demand value.
Press AMP or VOLTS together and hold until the peak value resets to zero (approx
