The other parts of the display are as follows:
•
Status box: show the operative mode symbols (see the table below).
•
Channel 1 box: show the CH1 measured value, engineering unit and input
mode.
•
Secondary value: show the measure or source value (CH2, Pressure, etc),
engineering unit and input or output mode.
Symbols
Numeric Pad active:
When this symbol appear on display, the instrument is waiting for a
numeric
input (e.g. in calculator mode)
Characters Pad active:
When this symbol appear on display, the instrument is waiting for a
string input
Battery level:
This animated symbol will show the level of charge of the rechargeable
batteries.
Data Hold:
H
This symbol appears on display when the measures are freezed by
pressing the [HOLD] key.
Zero function:
Z
This symbol appears on display when the [HOLD] key is keep pressed
for more than 2 seconds. It shows that the relative measuring is active.

Power supply

Calys60/80/120 can be powered from:
•
internal rechargeable Ni-MH battery.
Manuel d'intructions NTA47248-300A4
Description
•
External battery charger, supplied as a standard accessory (the batteries
must be installed).
For the IS models use the external battery charger in safe zone ONLY
The Ni-MH rechargeable batteries allows a long time operation and do not need
maintenance. The same batteries power both the instrument and the external
pressure modules. Battery life (typical):
10 h (8 h on IS models) on Tc and mV input/output (backlight Off)
4 h (3 h on IS models( with 20 mA simulation (backlight Off)
Recharging time (typical): 5 h (8 h on IS models) at 90 % and 6 h (10 h on IS
models) at 99 % with instrument switched off.
During operation a fully battery symbol "≠" will be displayed on the display. This
symbol means that the batteries are completely full. When the batteries will be
discharged the symbol "–" will appear and the instrument still has about 20 minutes
operation capability to end the running analysis.
The battery symbol indicates that a full charge is required. Use only the dedicated
battery charger supplied by AOIP SAS together the instrument.
CAUTION: Old batteries can leak and cause corrosion. Never leave run down
batteries in the instrument
THE INSTRUMENT IS SHIPPED WITH AN AVERAGE LEVEL OF BATTERY
CHARGE. AFTER UNPACKING, A FULL CHARGE OF THE BATTERY IS
RECOMMENDED, BY CONNECTING THE INSTRUMENT TO THE MAIN LINE
THROUGH THE BATTERY CHARGER (OFF CONDITION) FOR 8/10 HOURS.

Electrical connections

Appropriate extension wires should be used between the thermocouple (or
instrument under calibration) and the calys60/80/120 unless the thermocouple leads
allows direct connection. Make sure that both thermocouple and compensating cable
are connected with the correct polarity.
If in doubt, the polarity of the compensating leads can be checked by connecting a
length of lead to the indicator, shortening the free ends of the wires together and
noting that the indicator reading increases when the wire connection is heated. Color
