●5.1.3 Relationship between Battery Level Indicator and Sampling Time
The battery level indicator on GSP-501FT screen indicates the remaining battery power in five levels.
The indication of the battery level indicator and the sampling time are shown below.

Note

The values in Tables 1 & 2 are typical examples at a temperature of 25°C and atmospheric
pressure of 1 atm. Please note that these values are not guaranteed values. In low-
temperature environments, the sampling time may be shorter than the above tables.

The values in Table 2 are for reference only and vary depending on the manufacturer and
model number of the AA nickel-metal hydride batteries.

When the battery indicator is " ", the battery is running out. Replace the batteries.

If the battery runs out during the sampling operation, the integrated volume and sample
time immediately before the pump stops are recorded as the previous sampling result.
