Description

Easy-to-use upright high-speed isolated 4 or 8-channel multi-function logger

An easy-to-use upright device enabling isolated 4-channel multi-function input, the GL900 is capable of performing high-speed simultaneous measurements of voltage, temperature, and various other phenomena.

Voltage +/-20 mV to +/-500 V
Temperature Thermocouples:
K, J, E, T, R, S, B, N, W
Humidity 0 to 100%
(the B-530 option is required)
Pulse 4 channels
Count, Inst., Rpm
Logic 4 channels
‡ Select either Pulse or Logic

Data can be captured to PC-friendly USB memory sticks

Long-term data can be captured directly to built-in 256-MB flash memory or to an external USB memory stick at sampling intervals of from 1 ms to 1 min. For high-speed sampling at intervals faster than 1 ms, up to one million data points can be captured to internal RAM.

Internal flash memory (256 MB) × × × Approx. 1 hour. Approx. 11 hrs. Approx. 4 days Approx. 46 days
External USB memory stick (512 MB) × × × Approx. 22 hrs. Approx. 22 hrs. Approx. 9 days Approx. 93 days

The USB memory stick must be a standard model (without fingerprint recognition or other proprietary features).

Can be used as an X-Y recorder

The GL900 reproduces analog X-Y recorder movements and provides the illusion of pen up/pen down movements. It can be operated like an analog X-Y recorder and can also be used as a 4-pen X-Y recorder. The digital data format facilitates post-measurement confirmation of data values and report creation.

High-precision temperature measurement even during high-speed sampling

Lets users perform high-precision temperature measurements even during high-speed sampling – ideal for performing combined voltage and temperature measurements.

Comprehensive built-in trigger and timer functions

Using a combination of trigger and timer functions eliminates superfluous data and enables capture of only the required data.

Setting example 1

To perform measurement over a four-day period starting January 10

Timer setting Date and time Start setting January 10 00 hours 00 minutes
Stop setting January 14 23 hours 59 minutes
Trigger setting Start trigger Off
Stop trigger Off

Setting example 2

To perform measurements of abnormal signals during device operations

Timer setting Daily cycle Start setting 09 hours 00 minutes
Stop setting 17 hours 00 minutes
Trigger setting Start trigger Level CH 1 (3 V Rising)
Stop trigger Level CH 1 (2 V Falling)
Repeat On

Setting example 3

To perform measurements every 20 minutes

Timer setting Hourly cycle Start setting 00 minutes 00 seconds
Stop setting 20 minutes 00 seconds
Trigger setting Start trigger Off
Stop trigger Off

Setting example 4

To perform measurements for a period of one hour, every four hours, daily

With the timer set to daily cycle status, data is captured repeatedly for one hour every four hours.

Trigger setting Start trigger Off
