2020/2040 Logger General Questions

Can I read my data using notepad (.csv file)?

By using SquirrelView you are able to export data to .csv format to a preferred spread sheet.

Can I fit the logger to a wall?

Yes, a universal bracket is supplied as standard with each Logger. It can be adjusted to act as a wall bracket or desk stand.

How often does the Logger require calibration?

Drift is not expected although annual calibration is recommended. In real terms this is dependant upon use. Contact Grant Instruments for further details. The last date of calibration can be viewed via SquirrelView->Diagnostics->20xx logger

What is the Inter-channel isolation?

For 1F8 loggers, inputs on blocks A to D share a common measurement circuit and must be within ±25V of each other and within ±60V of the negative pin on the logger’s power supply.

For 2F8 loggers, inputs on blocks A and B share one measurement circuit and blocks C and D share another measurement circuit. Inputs on blocks A and B must be within ±25V of each other and within ±60V of the negative pin on the logger’s power supply. Inputs on blocks C and D must be within ±25V of each other and within ±60V of the negative pin on the logger’s power supply. Inputs on blocks A and B must be within ±60V of the inputs on blocks C and D.

For 2F16 loggers, inputs on blocks A to D share one measurement circuit and blocks G to K share another measurement circuit. Inputs on blocks A to D must be within ±25V of each other and within ±60V of the negative pin on the logger’s power supply. Inputs on blocks G to K must be within ±25V of each other and within ±60V of the negative pin on the logger’s power supply. Inputs on blocks A to D must be within ±60V of the inputs on blocks G to K.

For 4F16 loggers, there are four separate measurement circuits connected to four pairs of input blocks – A and B, C and D, G and H, and J and K. Inputs on each pair of blocks must be within ±25V of each other and within ±60V of the negative pin on the logger’s power supply. Any input on any block pair must also be within ±60V of any other input on any other block pair.

Caution: Voltages approaching 60V and above can cause personal injury.
